Perissa is a beach village, and its rhythm follows the season. The black-sand strip is at full tilt in high summer and winds right down in winter, so when you come shapes the whole trip — the temperature, the crowds, and how much is open. Here is how the year breaks down on Santorini's southeast coast. For how to reach the village, see our getting-to-Perissa guide.
The short answer
- Best months: May–June and September–October — warm, comfortable days around 20–28°C, mostly sunny, with fewer crowds. The ideal window for most visitors.
- Peak season: July–August — hot and lively at 30–35°C, festivals and a buzzing waterfront, but intense midday heat.
- Off season: November–April — cooler and wetter (10–16°C); much of the beach strip closes and the village is at its quietest.
Best months at a glance
| Season | Months | Weather | Sea | Verdict |
|---|---|---|---|---|
| Sweet spot | May–June & Sep–Oct | Warm 20–28°C, sunny | ~25°C into September | Best overall — warm water, thinner crowds |
| Peak summer | July–August | Hot 30–35°C, dry | Warmest, ~26–27°C | Buzzing but busiest and fiercest heat |
| Quiet season | Nov–April | Cool 10–16°C, wet spells | Cold; swimming over | Cheapest and calmest, but much is shut |
May–June & September–October — the sweet spot
For most travellers, late spring and early autumn are the best time to visit. Days are warm and comfortable (around 20–28°C) and mostly sunny, and there are fewer crowds than midsummer — with pleasant evenings for dining out and strolling the seafront. The sea is one of Santorini's warmest here: the black-sand east coast (Perissa, Perivolos, Kamari) runs about 1°C above the island average, peaking around 26–27°C in August and holding ~25°C into September, with the swimming season stretching May to November. So early autumn gives warm water and thin crowds together. You get the beach and the buzz without the peak-August crush or the fiercest heat.
July & August — peak summer
July and August are hot and lively, with temperatures of 30–35°C, dry and hot, festivals, and a waterfront in full swing. Over the Mesa Vouno headland at the neighbouring beach of Kamari, the long-running Santorini Jazz Festival brings open-air concerts to the Cine Kamari outdoor cinema in mid-to-late July (dates shift each year — check the current programme). It is the classic Greek-island beach summer — but the midday heat is intense, so plan sightseeing like Ancient Thera or the Mesa Vouno hike for the mornings and evenings, and expect the beach and buses to be busy. This is also meltemi season — the strong dry north wind that blows for days at a stretch in July and August; it whips up Santorini's north-facing beaches, but Perissa and Perivolos, facing south-east, are among the island's more sheltered strands, so they usually stay swimmable on windy days (and the wind tends to ease by evening). UV is strong from June to September: pack high-SPF sunscreen, a hat and water. For the peak months in detail, see our Santorini in July and Santorini in August guides.
Two seasonal extras worth timing
Beyond the weather, a couple of dates can shape when you come:
- The August grape harvest (vedema). Santorini's is one of the earliest wine harvests in Europe — the island's prized Assyrtiko and other volcanic varieties are picked from early-to-late August, when the wineries are at their liveliest with harvest tastings and events. If you love wine, midsummer has this extra draw on top of the beach.
- Greek Orthodox Easter. The movable Easter weekend (usually April, and the 12th in 2026) is one of the most atmospheric times to be on the island — candlelit processions, feasting and blossom, with mild spring weather and few tourists. It's an authentic, cultural alternative to a summer beach trip.
Which month suits you
- Warmest swimming: August and September, when the southeast-coast sea is at its warmest (~25–27°C).
- Sightseeing (Ancient Thera, the Mesa Vouno hike, Akrotiri): May–June or September–October, cool enough to climb and explore comfortably.
- Festivals and wine: July for the Santorini Jazz Festival, August for the grape harvest.
- Budget and quiet: the shoulder months and winter, when prices drop and the crowds vanish — accepting that much of the beach strip is closed.
November–April — the quiet season
From November to April Perissa is cooler and wetter, around 10–16°C with rainy spells. The beach strip winds down — the beach bars run roughly May to October, and many tavernas and hotels close for the season by the end of October — and the village is at its quietest. It is peaceful and cheap, but come knowing that much of the seafront will be shut.
