The Best Time for a Santorini Wine Tour
When to book a Santorini wine tour: why the harvest is in early August, which months the cellars close, and whether morning or sunset is the better slot.
Santorini’s wine calendar does not behave like a European wine region’s, and the main reason is that the harvest happens in early August — while the island is at its most crowded, and months before you would expect it.
That single fact reshuffles the usual advice about visiting wine country.

The harvest is one of Europe’s earliest
Picking on Santorini generally starts in the first half of August and runs through a fortnight or so, village by village. Domaine Sigalas’s 2025 harvest report has Assyrtiko and Athiri beginning on the 8th at Oia and Exo Gonia and finishing on the 23rd at Imerovigli and Pyrgos.
That is extraordinarily early — among the first harvests anywhere in Europe. The cause is the island’s climate: relentless sun, almost no summer rain, and vines that ripen fast on ground that holds very little water.
The practical consequence is that late August and early September are the most interesting weeks to visit a cellar, because the wineries are actually working. You get the smell of fermentation, machinery running, and staff who have something immediate to talk about. It is also, unhelpfully, peak season.
Month by month
May and early June — the best all-round window. Operators are running daily, the island is not yet full, the vineyards are green after spring, and the temperature is comfortable for standing in a vine field at midday. Sunset tours are bookable a day or two ahead rather than a week.
Late June to July — hot and busy. Everything runs, everything fills. Book the sunset slots several days out. Morning tours are markedly more pleasant at this point in the summer: cellars are cool, terraces are not.
August — harvest, and the peak of everything. The wineries are at their most interesting and the island at its most crowded. If you come now, book early and take a morning departure unless the sunset is non-negotiable.
September and early October — arguably the best month. The harvest has just finished, the cellars are full of new wine, the crowds have thinned, the sea is still warm and the light is better than it is in July. Most operators are still running daily.
Late October to April — the thin season. Most wine tours run May to October and either stop or reduce sharply outside that window. The featured sunset tour states its season plainly as May to October. Some cellars stay open for walk-in tastings year-round, but the guided catalogue shrinks to a handful, and a January visitor should not assume a wine tour is available at all.
Morning or afternoon?
A separate question from the month, and often the more important one.
Morning is better for the wine. The cellars are cool, the tasting rooms are quiet, the guide is fresher and has fewer people to divide attention between, and the identical three-cellar route costs materially less than the same tour run later. The three-winery tour with transfer runs at 11:40 and includes the cave wine museum.
Afternoon is better for the view. Those departures are sequenced to finish on a west-facing terrace at sunset, and there is nothing else quite like drinking a cold Assyrtiko on the caldera rim as the light goes. It costs more and sells out first. See Santorini sunset wine tours.
If you have two wine days, do one of each. If you have one, answer the sunset question first — it is the fork that decides everything else.
What the weather does to a tour
Santorini’s wind is the reason the vines are trained into baskets on the ground, and it is not gentle. On a windy day the vineyard stop is short and the terrace tastings move indoors, which changes the character of the afternoon but not its quality. Rain is rare between May and September and the tours run regardless.
Heat is the real variable. A midday vineyard walk in August is genuinely hot, and there is no shade in a Santorini vine field by design — the vines are knee-high. Hat, water, and the morning slot.
Frequently Asked Questions
When is the grape harvest in Santorini?
Generally the first half of August, moving village by village over about a fortnight — one of the earliest harvests in Europe. Domaine Sigalas’s 2025 report had picking start on 8 August at Oia and Exo Gonia and finish on the 23rd at Imerovigli and Pyrgos.
What is the best month for a Santorini wine tour?
September, narrowly. The harvest has just finished so the cellars are working, the crowds have thinned from the August peak, and operators are still running daily. May is the best alternative if you prefer a quieter island to a busier cellar.
Do Santorini wine tours run in winter?
Mostly not. The catalogue is built around a May-to-October season and thins out sharply outside it. Some cellars remain open for individual tastings, but the guided tours largely pause, so a winter visitor should check availability before counting on one.
Is it better to do a wine tour in the morning or the afternoon?
Morning for the wine — cooler cellars, quieter rooms, more guide attention, lower price. Afternoon for the sunset, which is what most people are actually buying. Both visit the same estates.
Will it be too hot in August?
In a vine field at midday, yes, it can be. Santorini’s vines are trained into low baskets on the ground, so there is no shade in a vineyard by design. Take the morning departure, wear a hat, and drink water between pours.
Does the wind affect the tour?
It can shorten the vineyard stop and move terrace tastings indoors, but tours run regardless. The wind is also the reason the vines look the way they do, so a guide will usually make a virtue of it.
