Best Time to Visit Samos
The best time to visit Samos depends on whether you prioritise beach conditions, hiking comfort or lower prices. Samos has a classic Mediterranean climate: hot, dry summers, mild wet winters, and a peak season shaped by the Meltemi Wind and warm Aegean Sea.
May–June & September–October: The Sweet Spot
These shoulder months strike the ideal balance: daytime temperatures hover at 24–28°C, the Aegean Sea warms to 19–24°C, rainfall drops to near zero (roughly 15 mm in May, 5 mm in June, 10 mm in September and 50 mm in October), and prices fall 20–30% below peak-season rates. Visitor numbers run 40–50% below the July–August peak, which makes taverna tables and beach space noticeably easier to find.
Conditions suit every activity. May and June deliver calm seas without Meltemi chop—ideal for beaches—while September and October hold sea temperatures of 22–24°C. Hiking is comfortable, including the Mount Kerkis ascent, and September coincides with the Muscat Wine harvest and pressing, making it prime time for winery visits.

Book early for late May and early June, when British half-term overlaps with Greek demand.
July–August: Peak Heat & Meltemi Wind
July and August deliver peak heat—31–33°C most days, often feeling closer to 40°C in full sun—and the sustained Meltemi northerly wind, which churns the north coast and can delay ferries by 1–2 hours. The Meltemi typically blows with sustained winds of 15–30 mph and gusts to 35 mph, leaving north-coast beaches choppy.
The south coast, sheltered by the Mount Kerkis ridge, stays markedly calmer, and inland villages run 3–5°C cooler than the coast. The sea peaks at 24–25°C.
If travelling in peak season, choose south-coast accommodation—see our where to stay guide—plan activities before 10:00 or after 18:00, and use SPF 50+.
Monthly Weather Averages
July and August are the hottest months, January the coldest, and December the wettest at roughly 157 mm. The table below summarises typical conditions month by month.

Winter (November–March): Quiet Season
Winter on Samos is mild—10–15°C most days—but wet, with the bulk of the island's annual rainfall arriving November through February. November sees around 90 mm over 10 rainy days; December is wettest at 157 mm across 13 days; January brings 138 mm and 12 rainy days. Nights fall to 7–9°C, and the Aegean cools to 15–17°C—too cold for all but hardy swimmers.
Infrastructure thins accordingly: many tavernas, hotels and car-hire offices shut from November to March, and ferry schedules reduce to 1–2 sailings per day—check current winter ferry timetables.
Winter suits travellers seeking solitude and off-season prices, with accommodation typically 40–50% cheaper. Wineries operate year-round, and hiking on Mount Kerkis is feasible on dry days—pack waterproofs and check the forecast.
Microclimates Across Samos
Samos is small, but its weather varies sharply across short distances. Mount Kerkis cools the island's interior, while the Meltemi wind separates a breezy north coast from a calmer, sheltered south. These differences matter when choosing beaches or accommodation.
Understanding the Meltemi Wind
The Meltemi is a seasonal northerly wind that blows across the Aegean, typically from June through September and peaking in July and August. On Samos it produces steady winds of 15–30 mph, with gusts occasionally exceeding 30 mph, and recent forecasts have shown gusts of 25 knots in the evening on exposed coasts. The wind cools the air pleasantly, but it whips up rough seas and sideways chop on north-coast beaches around Kokkari and Avlakia, and can occasionally disrupt ferry schedules. When the Meltemi blows hard, the sheltered south coast usually offers calmer conditions for swimming.
What to Pack by Season
Packing for Samos depends less on the month than on altitude and wind; evenings can stay breezy even in August. The UV index reaches 9–10 (Very High) in midsummer, and forecasters have rated it 8 (Very High) as late as 1 September, so pack SPF 30+ sunscreen, a wide-brimmed hat and UV-blocking sunglasses, reapplying every two hours, especially after swimming.
Seasonal Packing Checklist
- Summer (June–August): SPF 30+ sunscreen, hat, sunglasses, light layers for evening Meltemi breeze, refillable water bottle.
- Spring (April–May): light jacket, walking shoes, layers for 20–25°C days, swimwear.
- Autumn (September–October): swimwear, light fleece for evenings, sun protection, walking shoes.
- Winter (November–March): waterproof jacket (December rainfall peaks around 157 mm), warm layers, sturdy waterproof shoes.
Weather for Different Activities
Indicative sea temperatures run about 19–23°C in May–June, 24–26°C from July to September and 22–24°C in October, so swimming is realistic from May to October, peaking in July, August and September. Water lags behind air temperature, so a 25°C May day feels cooler than visitors expect. In July–August the Meltemi often brings side-on chop to north-coast beaches at Kokkari, Avlakia and Tsamadou while the south (Votsalakia, Psili Ammos, Ormos Marathokampos) stays calm; choose the shore by the day's wind, not the beach ranking. Verify current forecasts before travelling — beach ideas are in our things to do guide.
Hiking & Outdoor Activities
For walking on Samos, the practical windows are April to June and September to October, when daytime temperatures sit around 20–28°C. July and August exceed 33°C at midday, so summer hikes start before 07:00 with 2 litres of water and descent by midday. Mount Kerkis (1,433 m, Samos' highest summit) runs 3–5°C cooler than the coast but its slopes stay demanding even then. Easier walks include Vourliotes–Manolates and Potami. Winter walking is possible but short; expect rain and slippery stone. Verify current conditions locally before setting out.
FAQ
What is the hottest month in Samos?
July and August share the title, with daytime temperatures typically reaching 31–33°C and feels-like readings approaching 40°C during heat spikes. The Meltemi wind offers some relief, but it also churns up the sea along north-facing beaches, so swimmers often head to the calmer south coast instead.
Does it rain a lot in Samos?
Very little in summer. The dry period runs from May to August, when rainfall is close to zero. Most precipitation falls between November and February, with December the wettest month at around 157 mm. September is the transition month, typically seeing 2–3 rainy days.
When is the sea warm enough to swim in Samos?
The Aegean is generally swimmable from May to October. May–June brings sea temperatures of 19–23°C — refreshing but comfortable — while July to September peaks at 24–26°C. October stays pleasant at 22–24°C. Warmest water falls between mid-July and early September.
What is the Meltemi wind and when does it blow?
The Meltemi is a seasonal northerly wind that sweeps across the Aegean in July and August. It produces sustained winds of 15–30 mph with stronger gusts, raising rough seas on Samos' north coast while lowering air temperatures. The sheltered south coast is the usual alternative on windy days.
