Santorini, Greece

Set in the Mediterranean basin, Santorini (Greece) is best understood through its weather data: our 2015–2024 climate record puts its peak at a 100/100 sun score in June, exactly the kind of reliability you want for a beach trip.

July is the heat peak, averaging 29°C highs; January is the cool end, when nights dip to around 11°C. On the rain ledger, July is the safest bet at a 2% chance of a wet day, while December climbs to 30%. If 24°C is your bar for proper warmth, count on June–September.

That makes summer the statistical sweet spot (season score 99), with autumn a workable second; winter is where the odds thin out.
