The short answer
If you want warm sea + few crowds, come in late May or September. If you want peak Greek summer energy, come in July or August. If you want a quiet writer's retreat with the fireplace on, come in November to March.
Month by month
May — the shoulder begins
Air 22–26°C, sea 19–21°C by mid-month and very swimmable by the end. Wildflowers everywhere. Tavernas reopening for the season; never crowded. Long days. Possibly our favourite month — if the sea is warm enough for you, you have the place almost to yourself.
June — perfect, before peak
Air 26–30°C, sea 22–24°C. Locals are out swimming, but Athenian holidays don't start until July, so weekdays at the beach are quiet. Long evenings, mosquitoes start appearing — use the nets.
July — full summer
Air 30–35°C, sea 24–26°C. The town fills with Athenian families. Tavernas need reservations on Fridays and Saturdays. Weekday mornings at the beach are still calm. Book the villa early; July dates go first.
August — Greek high season
Air 30–36°C with occasional 38°C spikes, sea 25–27°C. Greece moves to the coast for the month. Locals are warm and friendly but everything is busier and more expensive. The villa books out in winter for August — if you want it, message us in February.
September — the locals' favourite
Air 26–30°C, sea at its warmest (25–27°C). The Athenians go back to work after the first week, beaches empty, tavernas still open, wineries pressing grapes. A magical month if you can come.
October — slow and golden
Air 20–26°C, sea 22–24°C and still pleasant for swimming until mid-month. A few rainy days possible. Light is gorgeous. Many tavernas are still open through Greek "Indian summer."
November to March — off-season
Air 8–18°C, sea 14–17°C (locals do swim — you might not want to). Most beach tavernas closed; village tavernas open year-round. Cold evenings, warm fireplace, dramatic light. Perfect if you're writing a novel, walking, or want central Athens within reach without summer chaos.
April — the awakening
Air 18–22°C, sea still cold (16–18°C). Almond and orange blossom in the inland villages. Easter is the high point of the Greek year — if you can come the week of Greek Easter (movable feast, usually late April / early May), you'll see Porto Rafti at its most authentic: midnight candle processions, lamb roasting on village squares, the local choir.
What to book around
Greek public holidays that fill up
- Greek Easter — biggest holiday of the year. Book very early.
- Assumption Day, August 15 — Greeks travel for the long weekend.
- March 25 (Independence Day) and October 28 (Ohi Day) — long weekends.
Athens marathon weekend
The original Marathon route ends in central Athens but starts ~25 minutes from us. Early November. Runners often book a quiet base on the east coast — message us if that's you.
Our take
Late May, mid-September, and the first week of October are the three windows we'd recommend to anyone who isn't tied to school holidays. Warm sea, mild evenings, half-empty beaches, every taverna still open, prices off-peak. The Greek coast is at its best then.← Back to all guides
