Month-by-Month Weather in Samos

Below is a traveler-friendly overview of typical weather patterns across the year. All temperatures are approximate averages based on long-term climatological data.

January — Cool & Rainy

• ️ High: ~15°C / Low: ~6–8°C
• ️ Most rain falls this month
• ️ Winter conditions with occasional showers

The winter in Samos, mild but wet, really begins around Christmas and continues during January. While sightseeing is still pleasant, hiking might be tough while beaches and swimming are totally off-season. Some snow is usual but only for a couple of days and mainly above 700m.

February — Mild Winter

• ️ Highs near ~14–15°C, lows ~6–7°C
• ☔ Frequent rainfall persists
• Winds keep days fresh

February is cute as the first signs of Spring might show up with wildflowers and some tree start blossoming, yet it remains in the heart of winter. People still prefer indoor activities and maybe a careful mountain jeep-safary could be a nice idea.

March — Spring Begins

• ️ High: ~20°C / Low: ~8°C
• ️ Showers decrease gradually
• ☀️ Days begin to lengthen

March signals the transition to spring. The sea temperatures are the coolest yet the green and flowery landscapes invite walkers and explorers to the mountains and the plains. Don’t miss this time.

 

 

April — Gorgeous Spring Weather

• ️ High: ~22°C / Low: ~11°C
• Moderate sunshine, reduced rain
• Sea temp starts rising near ~16°C

April is one of the first months where Samos becomes ideal for hiking, archaeology tours, low-season prices and much more to see and do. Orthodox Easter has most of the local traditional celebrations to experience and this might be the #1 reason not to miss Samos. Check our mySamos articles about Easter and get a glimpse of the warm and welcoming celebrations.

May — Warm & Pleasant

• ️ High: ~25°C / Low: ~14°C
• ☀️ Plenty of sunshine
• Sea temp ~18–20°C

May is often cited by mySamos experts as the perfect weather to combine everything on the island. The morning and noon are even good for swimming or sightseeing, the outdoor dining is a must while activites like hiking are still ideal. As the day goes by though, you can feel the chill… thus there is some quiet around nightlife …before peak summer crowds of late June show up.

June — Summer is here, summer Begins

• ️ High: ~32°C / Low: ~18°C
• Long sunny days
• ☀️ Minimal rain

By June, summer is in full swing. Enjoy nature but head to the beach. The sea warms significantly and cayak, diving or other activities (maybe beach volley?) are starting to warm up! All days are reliably sunny and rarely clouds appear. This month is ideal for beach lovers – still not full of July’s and August’s crowds.

July — Hot & Dry

• ️ High: ~34°C / Low: ~22°C
• ☀️ Almost no rain
• ️ Best beach month

Sunscreen first. With clear skies and high temperatures, July epitomizes Samos summer. Tourism high-season is here.

August — The crowds are hot – the weather is hot

• ️ High: ~35°C / Low: ~24°C
• Warm sea, hottest evenings
• ☀️ Dry conditions continue

August often records the warmest temperatures and warmest sea water (yupi!). Long beach days, long hot nights. Either stay for a sunset swim or prepare for the Samos cocktail bar tour! August has the cosmopolitan aroma you will not meet during the rest of the season. Sunscreen always with you to protect your skin. Night celebrations in Platanos or Vourliotes might get slightly chill but don’t overdo it.

September — Still Warm

• ️ High: ~30°C / Low: ~20°C
• ☀️ Sea still warm
• ️ Less crowded but still sunny

September offers peak summer conditions but these days are not the most. Fewer crowds make it the favorite month for the returning visitors. Some rain might appear but not to stop your activities and appetite.

October — Mild Autumn

• ️High: ~26°C / Low: ~14°C
• ️Rain starts returning
• Pleasant temperatures

October has mild weather making the season ideal for cultural touring, vineyard visits, and hiking. Leaves falling, colours changing, the days end sooner and the nights return slowly indoors.

November — Cooler & Wetter

• ️ High: ~22°C / Low: ~10°C
• ☔ Rain increases
• ️ Cloudier days

Autumn deepens – rain becomes more frequent, yet it is not winter; don’t worry! Slow travelers’ time, less visitors, off season still beautiful surrounding nature, full of choices.

December — Winter Returns

• ️High: ~16°C / Low: ~6°C
• ️High rainfall
• Mild winter days

December closes the year with mild but often rainy weather — perfect for cozy tavernas, museum visits, and low-season stays.
