When to visit Argentine wine country
Harvest, shoulder season, summer and winter compared — the honest, no-fluff month-by-month guide to when to go and why.
The honest answer is that Argentina’s wine country is good almost any month of the year. The country is huge, dry and sunny, and the wineries are open year-round. But “good” and “best for your trip” are not the same thing — and the difference between a harvest visit and a winter visit is bigger than most travelers realize. Here is the practical, no-fluff guide to when to go, based on what you actually want from the trip.
The one-line answer
If you want only one season: late March, April or early May — the post-harvest window in Mendoza, with autumn colors, mild weather, and wineries still buzzing from the new vintage. If you want the festival and the energy: March, around the Vendimia harvest celebration. If you want quiet, lower prices and almost no crowds: October–November or May.
The Argentine wine calendar in one paragraph
Argentina is in the Southern Hemisphere, so the seasons are flipped: summer is December–February, autumn is March–May, winter is June–August, spring is September–November. The wine year revolves around harvest in March in Mendoza, and slightly later (April) at higher altitudes like the Uco Valley and Cafayate. Pruning happens in winter. Spring brings the new vines back to life. Summer is hot and long. Each season has a different reason to come.
Autumn (March–May): the classic answer
If you imagine “harvest in Mendoza” — this is what you’re picturing. The vines turn deep red and gold, grapes are coming off the vine, the wineries are at full intensity, and the weather is perfect. Afternoons sit around 20–25°C / 70–77°F, evenings are crisp.
March is the most spectacular month and the heart of Vendimia, the National Grape Harvest Festival, with parades, folk music, beauty pageants and a famous show at the Frank Romero Day Amphitheatre attended by 20,000 people, with fireworks against the Andes. It is bucket-list territory. The catch: every winery, hotel and restaurant books out months in advance. If you want March, book by January at the latest.
April and May are the underrated months. The Vendimia crowds are gone, the vines are at their most photogenic, the new wines are being made, and prices drop 20–30% compared to peak. You can still experience harvest tours and even stomp grapes at some bodegas. This is what most experienced wine travelers quietly recommend.
In the high north — Salta and Cafayate — harvest happens a bit later, into April, because the altitude slows ripening.
Spring (September–November): the underrated answer
Spring in Mendoza is gentle, green and uncrowded. Vineyards come back to life, the cherry and almond trees bloom, the days warm up. October and November are among the best months for first-time wine travelers who want quality without harvest-season booking pressure. Wineries are open, restaurants are calm, the Andes are still dusted with snow.
For travelers who want wine country plus a touch of Patagonia, spring is the sweet spot: Mendoza is in excellent form, and southern Patagonia is just reopening for the season.
Summer (December–February): hot, festive, peak
Summer is when most Northern Hemisphere travelers come, which makes it the busiest, most expensive season. December and January can be very hot in Mendoza — 30–38°C / 86–100°F in the afternoons, occasionally pushing 40°C / 104°F.
The trick to summer is early mornings and long lunches. Visit wineries from 10am to 1pm, eat a long shaded vineyard lunch, then retreat from the heat. Evenings are still warm and gorgeous. Mountain trips (Aconcagua, mountain rafting) are at peak season, and many travelers combine wine with the Andes.
The downside: prices are high, wineries are booked, and the heat tires you faster than you think. Bring sunscreen — Argentina’s altitude makes the UV ferocious.
Winter (June–August): the secret season
Winter is the most overlooked season — and for the right traveler, it might be the best one. The vineyards are bare, but the snow-capped Andes are at their most dramatic, the wineries are nearly empty, and prices are at their lowest. You will get one-on-one attention from sommeliers who have time to talk because almost no one else is there. Tastings are intimate, slow and exceptional.
There is a brilliant niche move here: ski + wine. Las Leñas, a major Argentine ski resort, is just hours from Mendoza, and you can do mornings on the slopes, afternoons in bodegas. It is one of the most unusual wine-country itineraries on earth.
Winter days are crisp (12–18°C / 54–64°F) and nights are cold (just above freezing). The wines in your glass are warming reds, often paired with hearty locro stew (see our locro pairing guide) — the season feels like Argentine winter at its most authentic.
Quick comparison
| If you want… | Go in… | Why |
|---|---|---|
| Harvest festival & maximum energy | March | Vendimia, full activity, atmospheric |
| Harvest atmosphere, fewer crowds, autumn colors | April–early May | Underrated sweet spot |
| Mild weather, low crowds, mid-prices | October–November | Spring, vines reawakening |
| Northern Hemisphere winter escape & peak season | December–February | Hot, busy, expensive but lively |
| Cheap prices, intimate tastings | June–August | Winter, quiet, snow on the Andes |
| Ski + wine combination | July | Las Leñas is open + bodegas empty |
A few practical notes
- Book wineries in advance, especially in March, December, and on weekends. Some top bodegas (Catena Zapata, Zuccardi) book out 3–6 weeks ahead, sometimes longer for harvest season.
- Plan only two wineries per day. This is the single most important advice in this guide — palate fatigue is real. See our full 14-day Argentine wine itinerary for the proper pacing.
- Sundays. Many wineries are closed or have shorter hours on Sundays in Mendoza. Plan around it.
- The north is different. Salta and Cafayate have a slightly later, slightly cooler rhythm — see our Salta regional guide for specifics.
- Patagonia has a much shorter window: December–March is essentially the only practical season for cool-climate wine travel.
And one big tip
If you’re choosing between months, err on the side of shoulder seasons — May and October–November. You will get nearly all the experience for noticeably less money and far less stress. Most repeat visitors to Argentine wine country quietly agree this is the right call.

Quick answers
What is the best month to visit Mendoza wine country?
For most travelers, late March, April or early May — the post-harvest window — offers the best balance of weather, atmosphere and availability. March itself has the Vendimia harvest festival and the most energy, but books out months in advance. October and November are excellent shoulder months with mild weather and fewer crowds.
When is grape harvest in Argentina?
Harvest happens in March in Mendoza and slightly later — into April — at higher-altitude vineyards in the Uco Valley and the northern province of Salta around Cafayate. The Vendimia festival in Mendoza, with parades and the National Grape Harvest celebration, takes place at the start of March.
Is summer (December–February) a good time to visit Mendoza?
It works, but it is hot — often 30–38°C / 86–100°F in the afternoons. The trick is early-morning winery visits and long shaded lunches. Summer is the busiest season for Northern Hemisphere travelers, so book wineries and hotels well in advance, and expect higher prices.
Can you visit Argentine wine country in winter?
Yes — and for the right traveler it can be excellent. Winter (June–August) brings cool, dry days, snow-capped Andes, near-empty wineries and the lowest prices of the year. Tastings are intimate, and you can combine wine with skiing at Las Leñas. The catch is leafless vineyards.
How far in advance should I book wineries in Mendoza?
Three to six weeks for most wineries, longer for top names like Catena Zapata or Zuccardi, and at least three months ahead for harvest season (March) — including hotels and restaurants, which also book out fast around Vendimia.
