When is the Best Time to Visit Mendoza, Argentina?

So you’re dreaming of sipping Malbec beneath the snow‑capped Andes peaks, but you’re not quite sure when is the best time to visit Mendoza? Welcome to the eternal dilemma!

Each season here rewrites the script: spring wakes the vineyards with pastel blossoms and shoulder‑season bargains, summer turns the valley into a sun‑drenched playground of asados and outdoor sports, autumn steals the show with Vendimia harvest parades and vibrant foliage, while winter swaps pool days for ski runs and cozy barrel tastings by a crackling fire.

Think of Mendoza as a year‑round destination where you can choose your own adventure; the trick is matching your vibe and wardrobe to the calendar.

So grab a glass and let’s break down the pros, cons, and must‑see events for every season so you can time your trip like a local.

Spring in Mendoza

September, October and November

Pros of Spring in Mendoza

If you like the idea of vineyards waking up after their winter nap, spring in Mendoza is pure magic. The Andes Mountains are still sprinkled with snow, but down in the valley, the vines start pushing out bright green leaves and the orchards pop with blossoms.

Daytime temperatures hover around 20 °C (68 °F), making it perfect for patio lunches paired with a crisp Torrontés. Meanwhile, the evenings cool off just enough to justify a light jacket.

Vineyards and tasting rooms aren’t overcrowded and it’s easier to book a tasting or a table for lunch at some of the more popular bodegas that tend to get fully booked during high season.

Spring is ideal for outdoor activities like rafting, horseback riding, and trekking in the foothills of the Andes – you’ll have miles of trails practically to yourself!

Another added benefit is that because tourism is moderate, shoulder‑season prices are still in play and you can often find better rates on hotels. You may even want to consider staying at a local estancia at the foot of the Andes.

Cons of Spring in Mendoza

The downside of spring in Mendoza is that the weather is a touch unpredictable! Occasionally, the infamous Zonda winds sweep down from the Andes bringing sudden heat and dust.

Plus, there’s always a small chance of late frosts higher up in the Uco Valley. That being said, pack layers and you’ll be fine.

Summer in Mendoza

December, January and February

Pros of Summer in Mendoza

Summer turns Mendoza into a sun‑soaked playground. Daytime highs sit in the low 30s °C (mid‑80s °F), grapes are ripening fast, and the vibe is festive.

Long summer evenings mean more opportunities for al fresco dining. The long, warm nights beg for an asado under fairy lights, and rooftop bars in the city centre buzz until late.

Outdoor adventures reach peak adrenaline: think white‑water rafting on the Río Mendoza, sunset paddleboard sessions on Potrerillos Lake, and high‑altitude hiking at the foot of Mount Aconcagua.

One Mendoza summer event not to be missed is Fiesta de la Cosecha, which rolls out a symphonic concert right in the middle of the 3 hectares of vineyards at El Plumerillo Airport. Picture violins, cellos, and Malbec under the stars!

Cons of Summer in Mendoza

The summer heat in Mendoza is both a friend and a foe. Expect plenty of sunny days and hot temperatures in January and February. While this is great for poolside relaxation and sampling crisp white wines, the mercury occasionally leaps toward 38 °C (100 °F), which can make midday winery tours feel like a sauna!

Bring sunscreen, a hat, and try to schedule your tastings for the morning or late afternoon.

Tourism peaks during the summer holidays, leading to higher accommodation costs and busy wineries. Hotel rates and rental cars climb because local families are on vacation and travellers arrive en masse.

So, if you can handle the heat, the higher prices, and the crowds, summer rewards you with full‑throttle energy and late‑night fun.

Autumn in Mendoza

March, April and May

Pros of Autumn in Mendoza

Ask any wine aficionado and they’ll tell you that autumn is the best time to visit Mendoza!

Harvest season, locally known as the Vendimia, kicks off with a bang in March. The National Grape Harvest Festival, known as Fiesta Nacional de la Vendimia, is celebrated with beauty pageants, traditional dances, folkloric musicians, elaborately decorated floats, a spectacular final show at the Frank Romero Day Amphitheatre, and the crowning of the Harvest Queen.

You’ll be clapping along with 20,000 other people as fireworks light up the Andes backdrop – truly bucket‑list stuff.

An autumn visit to Mendoza also brings the possibility of taking part in special harvest tours where you can actually stomp grapes with your feet (this is known as vino patero) and taste juice straight from the press!

Weather‑wise, afternoons hover in the mid‑20s °C (low‑70s °F). Warm days and cooler nights are ideal for exploring the vineyards, hiking without intense summer heat, or going on an Andes excursion to the High Mountains.

Meanwhile, the hillsides morph into a patchwork of reds, oranges, and golds making the vineyard landscapes especially picturesque.

Autumn is my favourite time of year to visit Mendoza – I love the milder weather and changing foliage, but there’s still enough on the schedule!

Cons of Autumn in Mendoza

What’s the downside of autumn in Mendoza? With Vendimia in full swing, accommodation sells out months in advance, and traffic around the event venues can snarl. Because this is a popular time to visit Mendoza, you’ll want to book your hotel and arrange your tours well in advance.

By late April, the temperature dips and some wineries shorten opening hours meaning fewer options if you visit later in autumn.

Winter in Mendoza

June, July and August

Pros of Winter in Mendoza

Winter in Mendoza is more about cozy malbec‑by‑the‑fireplace vibes than sun‑kissed vineyards, but don’t write it off!

One of the pros of visiting Mendoza in winter is that there are fewer tourists and you can often get discounted hotel rates. This means you can take your hotel budget and upgrade to a fancy wine hotel. There are deals to be had, so have a look at properties you normally wouldn’t consider!

Snow blankets the high Andes turning it into a playground for winter sport enthusiasts.

Las Leñas is a high-mountain ski resort located in the heart of the Andes Mountains. Its base sits at 2,240 metres above sea level while its summit is 3,430 metres high. It has 30 ski runs and a season that runs from June to September. That means you can carve fresh powder in the morning and sip barrel samples back in the valley by mid‑afternoon.

Perks include gloriously clear mountain views – winter brings the least haze!

Several wineries host intimate locro‑and‑Malbec lunches for Argentina’s Independence Day on July 9th – great if you’re keen on comfort food.

Cons of Winter in Mendoza

The downside is that the vineyards won’t be looking their most beautiful as all the vines will be bare. A handful of boutique producers also shut their doors for annual maintenance, and shorter daylight hours can limit your daily mileage if you’re road‑tripping.

Crisp daytime temps of 12–15 °C (mid‑50s °F) give way to chilly nights that hover around freezing. While Mendoza’s winters are relatively mild compared to other parts of the country (I’m looking at you Patagonia!), it can still get chilly, especially at night and in the mountains.

Dress warm, rent a car with good heating, and enjoy getting the region almost to yourself.

So, when is the Best Time to Visit Mendoza?

Ultimately, Mendoza’s wineries and the scenic Andes backdrop ensure an unforgettable visit any time of year, but knowing what each season offers will help you plan the perfect escape.

If vibrant festivals, harvest activities, and lively crowds excite you, aim for late summer or early autumn.

If you prefer a tranquil getaway with mild weather and fewer tourists, consider spring or winter.

If warm weather, green vineyards, and outdoor adventure top your list, summer is your season.

That means the best time to visit Mendoza is entirely up to your wants and what you’re hoping to experience during your trip! Just pick your vibe and don’t forget to raise a glass to the Andes while you’re there.
