Santorini weather is defined by a classic Mediterranean climate with hot, dry summers and mild, wet winters. As shown in the live forecast above, conditions are generally stable, making it a year-round destination, though the best time for clear skies and warm sea temperatures is between May and October.
What is the typical weather pattern in Santorini?
Santorini experiences long, sunny summers from June to September, with average highs around 30°C and very little rainfall. Winters from December to February are cooler, with highs near 15°C and more frequent rain. The island is also known for the meltemi wind, a dry northerly breeze that peaks in July and August, providing natural relief from the heat.
How does the weather change across the year?
Spring (March to May) sees temperatures rising from 17°C to 24°C, with blooming wildflowers and fewer crowds. Autumn (October to November) remains pleasant, with sea temperatures still warm enough for swimming into October. For those checking santorini weather monthly, the shoulder months of May and October offer the best balance of warmth and lighter tourist numbers. If you are planning ahead, a santorini weather forecast 14 days or weather in santorini 10 days will give reliable guidance, though longer-range outlooks like a santorini weather forecast 30 days are less precise.
What is the weather like in Santorini in October?
October is mild and pleasant, with average highs around 23°C and sea temperatures still near 22°C. Rainfall increases slightly, but you can expect many sunny days, making it a good time for sightseeing and swimming.
Is May a good month to visit Santorini?
Yes, May offers warm days around 24°C, blooming landscapes, and fewer tourists than summer. The sea is still a bit cool for some, but it is ideal for hiking and exploring without the intense heat of July or August.
Does Santorini ever get very cold?
Winters are mild, with lows rarely dropping below 10°C. Snow is extremely rare, though rain and wind can make it feel cooler. For those used to santorini weather fahrenheit, winter highs are around 57°F.
