Wine harvest season by hemisphere: what you can actually see

Harvest in Napa Valley starts in August. In the Cape Winelands it starts in January. The two are six months apart, and that gap is the whole logic of the wine calendar: the vine goes through the same sequence on both sides of the equator, shifted by about half a year. Visit Napa Valley says harvest typically starts each year in August, and South African Tourism says harvesting happens between January and April.

Everything below hangs on that offset and on one caution. The months we give are windows for a typical year. A given year can land weeks away from them.

We mark a region in the tables only when we could open an official, consortium or tourism-board page that names the months. That left seven northern rows and three southern ones. The regions we could not confirm are named further down and left out, not estimated. This page is part of our guide to when to go.

Sonoma County Tourism lists the stages with months: dormancy from November to February, bud break from mid-March to April, flowering from mid-April to June, fruit set in May and June, veraison in July and August, harvest from August to October. Veraison is the change of color in the berries, and the same page says it takes roughly six weeks. Our glossary has the other terms.

The southern column in the table is our own arithmetic, not a published calendar. We moved each month by six. It is a rule of thumb, and it frays at the edges: a pure shift of August gives February, while South African Tourism puts the first picking in January.

Two regions start early. Wines of Greece says Santorini's harvest is one of the two, hardly three, earliest in the country and usually starts at the beginning or in the middle of August. In Provence, the rosé producers' council says picking begins in the second half of August on the coast and runs to October at the latest.

Champagne has the widest window of the regions we could confirm. The Union des Maisons de Champagne gives late September to early October for ripeness in a normal year, then adds that in exceptional years ripening can come at the end of August or in the middle of October, almost two months apart. The Champagne committee's own site says picking used to start in September and now starts increasingly earlier. We marked September and October and you should read that as the center of the range, not its edges.

The Chianti reading comes from one year: the consortium wrote that its harvest had returned to traditional times, and we use it only because the consortium itself calls that timing traditional. Read the Chianti and Douro rows as a guide to the month, not to the week. For the day a particular estate starts picking, nothing on a page can tell you.

The Cape starts first. Wesgro, the Western Cape's trade and investment agency, says harvest begins in early to mid-January depending on the cultivar, with harvest festivals running to March. A 2023 report from the industry body WOSA, read on an archived copy, calls early February the usual time. The two sources disagree by a few weeks, which is what a start that depends on the grape looks like. The Cape Winelands row is wide for that reason.

In Australia we could confirm one region. Hunter Valley Wine and Tourism says harvest starts around the end of January and continues until March, and the same page puts summer temperatures at 28 to 30 C on average, with thunderstorms. Harvest in the Hunter is its hottest season.

For Chile we have a national statement and no regional one. Chile Travel, the national tourism board, says grapes reach full ripeness between March and May. It does not say this about Chile's individual valleys, so the row is for the country.

Because the grapes, not the calendar, decide. Picking starts when the fruit is ripe, and ripeness follows the weather of that season. The Champagne gap of almost two months between an early and a late year is the clearest example we found in an official source. In New Zealand, the growers' body says in a recent vintage release that harvest dates have moved forward by several weeks in recent years and that January to March are the critical months for growing and ripening grapes (NZ Winegrowers). It gives no typical window, so Marlborough has no row in the table.

If your dates are fixed, pick the region by the middle of its window, not the start, and do not book a non-refundable flight for one specific week of picking.

A window of four months, like the Cape's, is easier to hit than a window of one, like the Okanagan's single marked month. Fewer marked months is a sign of how little we could confirm, not of a short season. For weather outside harvest, see weather and climate by wine region.

Not always. Visit Napa Valley says November is a more relaxed time after the harvest parties end, and that this is when the colors of autumn are on full display. In a region where picking runs from August to October, the gold vines arrive when most of the fruit is already in. A visitor chasing both gets them together, if at all, only in the last weeks.

Heat is the second catch. The Hunter's harvest is in its summer. If you do not like 28 to 30 C and thunderstorms, a Hunter harvest trip is the wrong trip, and our guide to choosing a wine tour is where the format question starts.

The third is what we could not confirm. We found no official source on whether cellar doors shorten hours or take fewer walk-ins during picking. Tourism boards promote harvest as event season, which is their job. If one small producer is the reason you are going, write to them first.

Every one of these has a harvest, and every one is missing because we could not open a source that states a typical window.

• Bordeaux: no official page with months that we could open.
• Burgundy: the wine board's press release we read covers one year only, so it is not a typical window.
• Langhe and Barolo, Veneto, Sicily and Campania: no consortium page confirmed.
• Rioja: the regional wine site lists one winery's harvest experience for September and October, which is a winery, not a region.
• Penedes and Priorat: the tourism board dates its harvest festival in September, and a festival is not the picking.
• Lisbon and Arrabida: no official window found.
• Kakheti: the national wine agency publishes one page per harvest year, but no typical window we could read.
• Niagara-on-the-Lake: the growers' report we opened covers a single year.
• Mendoza, Barossa, Yarra Valley, Marlborough and Waiheke: no official typical window opened.
• Margaret River: the association's vintage reports describe starts from mid-January to two or three weeks later than normal, which is a spread, not a window.

If you see a month printed for one of these elsewhere, check what it cites. When we find an official page, the row goes in.

We opened each page on 2026-09-30 and took the months from its text. Where a page described a single year, we used it only when the source itself called the timing traditional, and we said so. Growth-stage months come from Sonoma only; the southern months in the stage table are our shift of six. The Napa, Sonoma and WOSA pages refused or no longer served an automated request, so we confirmed them on copies at web.archive.org. The Okanagan line comes from a 2020 post about that October, so treat it as a loose guide. The harvest lines for Napa, Champagne, Provence, Chianti, the Douro, Santorini, the Okanagan, the Cape, the Hunter and Chile come from the pages below.
