The Best Time to Visit Mendoza's Wine Country

When Is Harvest Season in Mendoza?

Harvest generally takes place from late summer into early autumn, with the main period typically falling between February and April. Some sources describe the picking calendar starting even earlier for a few early-ripening varieties.

The exact timing varies by:

• grape variety
• vineyard altitude
• wine region
• weather
• ripeness targets

Earlier-ripening grapes may be picked first, and higher-altitude vineyards, such as those in the Uco Valley, can harvest later. That means you may see active harvest in one part of Mendoza while another vineyard is still waiting.

Is Harvest the Best Time to Visit Mendoza?

For many wine lovers, yes. This is vendimia, the grape harvest, and it is the season the region organises itself around. Cellars are working, not performing: you may see grapes arriving at the wineries, sorting tables running, fermentation under way, vineyard workers and harvest machinery, special winery events and fuller tasting rooms. The whole wine region feels more active.

However, harvest season also means:

• more visitors
• more demand for tours
• busier winery restaurants
• more pressure on reservations

If you want the strongest wine atmosphere, harvest is excellent. If you prefer quiet tastings, another season may suit you better.

February to April: Harvest, and the Busiest Weeks

The Fiesta Nacional de la Vendimia, which has run annually since 1936, culminates in the first week of March and is Argentina’s biggest harvest festival. It is spectacular and the city is full. Book tours, restaurants and hotels much further ahead than you would otherwise.

The vineyards are green and heavy with fruit, and the crates at the row ends are the photograph everyone comes home with. Days are warm, and during April the leaves start to turn.

Trade-off: the busiest weeks of the year, and the winery restaurants that seat limited covers are the first things to go.

February in Mendoza

February is hot, sunny and increasingly active in the vineyards, and some early harvest activity may already be under way.

Good for: summer atmosphere, pools, long days, vineyard views and early harvest energy.

Considerations: afternoon temperatures can be intense. If you are planning bike wine tours, long outdoor walks or vineyard activities, start early. Air-conditioned transport becomes especially valuable.

March in Mendoza

March is one of the most exciting months for wine tourism. Harvest is in full swing in many areas, and the region feels deeply connected to wine.

Why March is popular: active vineyards, harvest atmosphere, wine-related events, and weather that is warm but often more manageable than peak summer. It is one of the strongest months for first-time wine visitors.

Main drawback: it can be busy. Book wineries, winery lunches, private tours and popular hotels well in advance.

April in Mendoza

April is one of the best all-round months. Harvest continues or winds down depending on the vineyard, while autumn colours begin to change the landscape.

Why April is excellent: milder temperatures, beautiful vineyards, less intense heat, good conditions for touring, and fewer visitors than the peak harvest weeks. If photography and comfortable weather matter, April is especially attractive.

May to August: The Quiet Months

Winter arrives in June. The vines are bare and pruned back to spurs, the Andes carry real snow, and the region gets much quieter.

This is often the best-value time to come and the easiest time to get a table at the estates that are otherwise hard to book. The wine does not care what season it is, the cellars are warm, and a tasting room with four people in it is a better experience than one with forty.

Trade-off: several premium estates cut their opening days, some close for part of the winter, and the vineyards are not photogenic. Dress properly: most of the Uco Valley’s vineyards sit between about 1,000 and 1,500 metres, several hundred metres above the city, and it is noticeably colder there.

May in Mendoza

May is late autumn. The vineyards can still show beautiful colour, but temperatures are cooler and the wine country becomes noticeably quieter.

Best for: slower travel, lower crowds, photography, relaxed tastings and cooler weather.

Less ideal for: people wanting active harvest scenes, and travellers who expect green vineyards.

June in Mendoza

June marks the beginning of winter. The vines are dormant and the vineyard scenery becomes more minimal, but the Andes can look spectacular: snow on the mountains creates some of the clearest visual contrasts of the year.

Best for: quiet wineries, mountain scenery, fewer tourists and cosy winery lunches.

Considerations: mornings and evenings can be cold, so bring layers.

July in Mendoza

July is one of the coldest months. Wine tourism still operates, but the atmosphere is very different from harvest: bare vines, cool weather, snow on the Andes and quieter tasting rooms. Argentina’s winter school holidays also fall in July, when domestic visitors pass through Mendoza on their way to the ski resorts, so the city itself can be busier than in June or August.

It can be a very pleasant time at the wineries if you dislike crowds.

August in Mendoza

August is still winter, but the transition toward spring begins. The vineyards remain mostly dormant, while the days gradually become milder.

Best for: low crowds, wine-focused trips, mountain views and quieter premium tastings. If your priority is the wine, not the vineyard scenery, August can work very well.

September to November: The Best Photographs

Spring. New growth comes through bright green while the peaks still carry winter snow, which is the combination that makes Mendoza look like the postcards. Days are mild, the light is clean, and the harvest crowds have not arrived.

If your priority is what the place looks like, this is the window. It is also comfortable for anything outdoors. The wine and bike day, which pairs a ride through the Luján de Cuyo vineyards with a second ride beside the Potrerillos reservoir in the Andes, is at its best in spring. (our breakdown →)

Trade-off: not much is happening in the cellars. You are seeing the place, not the process.

September in Mendoza

Spring begins to change the landscape. Vineyards start returning to life, and outdoor experiences become more appealing.

Why September is good: fresh vineyard growth, milder weather, lower crowds than at harvest and comfortable touring. It is a strong shoulder-season month.

October in Mendoza

October is one of the best months for a balanced wine trip. The vineyards are green, temperatures are comfortable and winery lunches can often be enjoyed outdoors.

Best for: vineyard scenery, outdoor dining, cycling, winery tours and couples. It is one of the easiest months to recommend.

November in Mendoza

November brings warmer temperatures and lush vineyards. It feels close to summer without always reaching the hottest conditions.

Best for: outdoor wine tourism, vineyard hotels, pool weather, long lunches and green vineyard scenery. For many travellers, November combines comfortable weather with the full green of the vineyards.

December and January: Hot, and Busy with Argentines

High summer, and hot, regularly into the mid-30s Celsius. This is when Argentina takes its own holidays, so the region is busy with domestic visitors more than international ones.

Tours run on their usual afternoon schedule, which in December means the hottest part of the day is spent in an air-conditioned van, not a vineyard. That is not the worst arrangement.

Trade-off: the heat is real, and outdoor tastings at midday are less pleasant than they sound. Book morning departures if you can.

December in Mendoza

December is summer. Expect strong sun, warm afternoons, green vineyards, outdoor dining and pool weather. It can be a wonderful month if you enjoy heat, although long outdoor activities can be tiring.

January in Mendoza

January is usually one of the hottest periods, and it is not the best month for everyone.

Good for: resort stays, swimming pools, summer atmosphere and early-morning winery visits.

Less ideal for: afternoon cycling, long outdoor tours and travellers sensitive to heat. If you visit in January, choose accommodation with a pool and plan outdoor activity earlier in the day.

Best Time for Each Wine Experience

Best Time for Harvest Experiences

Choose February to March. This is when you are most likely to feel the active rhythm of harvest. Some wineries may offer grape-picking experiences, harvest lunches, special tastings or behind-the-scenes production tours. Availability varies by winery and year.

Best Time for Autumn Vineyard Colours

Choose April to early May. This is one of the most photogenic periods: the vineyards can shift from green to yellow, orange, red and brown, and the mountain backdrop makes the scenery especially dramatic.

Best Time for Green Vineyards

Choose October to February. Spring and summer give you the lush vineyard look many travellers imagine before visiting Mendoza.

Best Time for Snow-Covered Andes Views

Choose winter and early spring. June through September can provide striking mountain scenery. The vines themselves are less dramatic then, but the Andes can be spectacular.

Best Time for Winery Lunches

Winery restaurants operate year-round, but outdoor dining is most pleasant in spring, early summer and early autumn. October, November, March and April are particularly attractive. Mendoza wineries with lunch covers where to book.

Best Time for Bike Wine Tours

Choose spring or autumn: September, October and November, or March, April and May. These periods avoid the worst summer heat. Winter can also work on clear days, but mornings may be cold. Mendoza bike wine tours compares the options.

Best Time for Photography

There is no bad visual season, only a different look.

Best Time by Wine Region

Best Time for Uco Valley

The Uco Valley can be visited year-round, and each season has its own advantage:

• Harvest: wine activity
• Autumn: vineyard colour
• Winter: snowy mountains
• Spring: green vineyards
• Summer: bright, dramatic landscapes

Because the Uco Valley sits closer to the Andes and its vineyards are higher, temperatures can feel cooler than in Mendoza city. Bring layers. The Uco Valley wine guide covers the valley in detail.

Best Time for Luján de Cuyo

Luján de Cuyo works well throughout the year. It is particularly good in March, April, October and November, when weather, vineyards and outdoor dining all come together.

Best Time for Maipú

In Maipú, cycling and outdoor touring are a big part of the day, so spring and autumn are especially comfortable. Summer bike tours can be very hot. Winter is quieter and a good choice for winery visits without cycling.

Best Time by Type of Trip

Best Month for a First Mendoza Wine Trip

If we had to choose one month: April. Harvest may still be going on in higher vineyards, temperatures are milder, autumn colours begin and outdoor touring is comfortable. October and November are equally strong if you prefer green vineyards.

Best Month for Wine and Scenery

Choose April for autumn, or October–November for spring.

Best Time for Couples

For couples, prioritise April, October or November: comfortable temperatures, attractive vineyards, outdoor dining, less extreme heat and good conditions for long winery lunches. Harvest season is more exciting but also busier. Mendoza wine tasting for couples has more ideas.

Best Time for a Honeymoon

Spring and autumn are particularly good. A vineyard hotel is more enjoyable when you can use the terrace, gardens, pool and outdoor restaurant without extreme summer heat.

Best Time for Budget Travellers

Lower-demand periods can offer better value, and winter is often quieter. You may find easier hotel availability, fewer crowds and more relaxed wineries, although the vineyard scenery is less lush.

Best Time to Avoid Crowds

Choose May, June, August or September. Avoid major wine-event periods and harvest weekends if crowds bother you, and remember that July brings Argentina’s winter school holidays.

Best Time for Serious Wine Lovers

Serious wine travellers can enjoy Mendoza year-round, and the quieter months can be excellent: tasting rooms are calmer, staff may have more time and premium visits can feel more personal. If vineyard appearance is secondary, winter can be surprisingly rewarding.

Best Month for Wine Festivals

Mendoza’s major wine celebrations are linked to harvest season. If events and local wine culture are central to your trip, late February and March are the most important period to consider. Exact festival dates change each year, so check the current calendar before booking flights.

Best Time for a 5-Day Wine Trip

A five-day wine trip works best when temperatures are comfortable: March, April, October and November. That makes it easier to combine Luján de Cuyo, the Uco Valley, Maipú and city time without the weather becoming the main issue. The Mendoza wine trip guide has day-by-day itineraries.

Weather in Mendoza Wine Country

Does Mendoza Get Rain?

Mendoza has a dry climate. Rainfall is low, but summer thunderstorms can occur. The dry conditions are one reason irrigation is so important to Mendoza’s vineyards. Even in a dry region, check the forecast before a long outdoor tour.

Is Mendoza Very Hot in Summer?

Yes, it can be. December through February can bring strong afternoon heat. For summer trips:

• start tours early
• use sunscreen
• carry water
• wear a hat
• choose air-conditioned transport
• avoid heavy outdoor activity at midday

Is Mendoza Cold in Winter?

Yes, especially at night and in the morning, although daytime can still be pleasant in the sun. Layers are essential. The Uco Valley can feel colder than Mendoza city because of its elevation and its closeness to the mountains.

The Things That Are True All Year

Sun protection, always. Mendoza sits high and dry, and the light is severe in every season. Every operator’s what-to-bring list mentions it.

A layer, always, if you are going to the Uco Valley. The valley is several hundred metres higher than the city, it cools fast after the sun drops, and the afternoon wind gets up. Guests underdress for it in January as often as in June.

Hail is the region’s defining risk. The black mesh you see stretched over the rows is hail netting: a summer storm can strip a vineyard in minutes. It is also the quickest way to tell a Mendoza vineyard photograph from a Californian one.

Free cancellation. Every tour listed on this site cancels free up to 24 hours before, which helps in a region where weather occasionally closes a mountain road.

Winery Opening and Booking Through the Year

Do Wineries Close in Winter?

Many remain open, and winter is not a dead season for wine tourism. However, some premium estates cut their opening days, some restaurants reduce their days, outdoor activities may change and specific visitor programmes vary. Always check directly before travelling.

Are Wineries Open During Harvest?

Yes, but harvest is a working period. Some wineries may alter tour routes, limit access to production areas or offer special harvest experiences. Popular wineries also become busier.

Do You Need to Book Earlier During Harvest?

Yes. Book well ahead for premium wineries, restaurant lunches, Uco Valley tours, private drivers and vineyard hotels. March can be particularly popular.

Frequently Asked Questions

What is the best month to visit Mendoza for wine tasting?

March, April, October and November are the strongest choices, and April gives the best overall balance for a first trip.

When is grape harvest in Mendoza?

Harvest generally runs between February and April, depending on grape variety, altitude and weather.

Yes. March is one of the most exciting months because harvest activity is high and the Vendimia festival culminates in early March. It is also busy, so book early.

Is April a good time to visit Mendoza?

Yes. April combines milder temperatures with autumn vineyard scenery and is one of the best all-round months.

Is Mendoza worth visiting in winter?

Yes. Many wineries stay open, crowds are lower and the snow-covered Andes can be spectacular. Some premium estates reduce their opening days, so check before you go.

So When Should You Go?

For a first wine trip, choose April: comfortable weather, autumn colour and the last of the harvest in higher vineyards. If you would rather see green vineyards and eat outdoors, choose October or November.

For harvest energy and the working cellars, come in late February or March, and book early. For quiet wineries, snow on the Andes and the easiest access to the good estates, choose June or the rest of winter, with a coat. Choose summer if you enjoy heat, long sunny days and vineyard resorts with pools.

Mendoza has no bad wine season; the experience changes with the month. Whichever you pick, the region you choose matters as much as the month, and that is worked through in Mendoza’s wine regions compared.
