Is August 2027 a good month to visit Santorini?
Packed — August is Santorini's busiest month: the typical day is busier than 88% of its year.
If you are coming for something that only happens in August, that is the trade. If not, January is quieter.
Calm · Lively · Busy · Packed rank a day against Santorini's own year — not a headcount.
This month's verified events: Feast of the Assumption (Dekapentavgoustos) (15).
August 2027 is peak-season Santorini: hot and dry, around 28°C / 83°F, and Busy or Packed on all 31 days — 20 of them Packed, the other 11 Busy.
No — not if you want Santorini to yourself. Every one of August's 31 days in our window is Busy or Packed, and the typical day is Packed. It is crowded throughout. Expect around 28 °C by day, with rain on about 2 days. The crowd comes with the school holidays in the Netherlands, Germany and France. Cruise ships call on 30 of the 31 days, 5 at once on Monday 30 August. Feast of the Assumption (Dekapentavgoustos) falls on 15 August. No week of August is meaningfully quieter — the typical day is Packed throughout; pick by day instead. For similar weather with fewer people, come in September or October. The crush is at Oia at sunset; the quiet is at the caldera path between the towns.
In short, worth it for the peak buzz, if you can take the crowds.
Among the 12 months we forecast for Santorini, August ranks 2nd for crowd pressure. Its heaviest day is Tue 10 Aug, busier than 99% of the year; its lightest is Wed 18 Aug at 66%.
Preparing pays off in a month like this: timed-entry tickets and pre-booked tours turn the queue time into sightseeing time. see the options →
Plan around the heat — around 28°C by day.
Refilling costs nothing and saves the walk to find a shop.

How busy is Santorini in August?
The busiest days are the 10th, 15th, 24th and 30th, and 27 more.
Cruise ships are in port on 30 of 31 days; the heaviest is Mon 30 Aug, 5 ships in at once. Those mornings fill the squares first — start early, or save them for indoors.
The month is not one thing: its lightest day sits at 66% of the year and its heaviest at 99%, so where you land inside it matters. Daylight runs about 13 hours.
Either side of it, September is a little calmer.
The lightest days are the 8th, 18th and 29th. Still busy — but the easiest of the month.

- The heaviest port day is Mon 30 Aug — 5 ships in at once. See the marquee sights on a lighter day, or be there for opening time.
- On the busy days, the walk-up queues for the big sights are the biggest time-sink — a timed-entry ticket skips them, which is where a busy month is won or lost.
Travelling on a busy day?
Timed-entry and skip-the-line tickets turn queue time into sightseeing time — sort them before you fly.
