What is the weather like in Greece in 2026?

HNMS broadly divides the year into a colder, rainier stretch from mid-October to the end of March, and a warmer, largely dry stretch from April to September. January and February are typically the coldest months. The warmest stretch usually sits in late July and early August, when mean maximum temperatures often fall in a roughly 29–35°C band depending on station and setting.

Winter bad-weather spells are often broken by sunny intervals, traditionally remembered as Alkion days in January and early February. Summers bring long clear skies, with short mainland thunderstorms more common than week-long grey spells. Detail pages: Summer heat, Winter cold, and Rain.

Attica and much of eastern Greece lean drier inside the Mediterranean frame. Northern and western Greece run wetter. Aegean and Ionian islands usually stay milder in winter than inland northern plains. Coastal sea breezes and Aegean Etesian (Meltemi) winds temper summer heat for many island and shore towns: Meltemi winds.

Athens stacks urban heat on Attica dryness: Living in Athens. Thessaloniki feels cooler and damper in winter. Crete’s lowlands stay among the milder winter options: Best climate and Where to live in Greece. Housing quality decides indoor comfort as much as the forecast: Utilities, internet and transport.

Bring a summer kit for dry heat and a winter kit for damp cool rather than assuming one wardrobe works. Ferry and intercity bus plans need weather buffers in winter and Meltemi weeks in summer. If you work from home, test afternoon glare and night sleep in the exact room you will use; Athens west-facing rooms and exposed Cyclades terraces fail that test for different reasons.

Job and school calendars rarely follow tourist seasons. September can still feel hot in Attica while northern classrooms already need jackets at dawn. Use Where to live in Greece to shortlist cities after you decide which season you refuse to suffer.
