Greece Weather at a Glance

Greece enjoys a Mediterranean climate, which means:

• Hot, dry summers (June to August)
• Mild and colorful springs (March to May)
• Warm, pleasant autumns (September to November)
• Cool, greener winters (December to February)

However, the weather varies across the country. In winter, the Greek islands remain warmer than many places on the mainland, whereas temperatures in the northern regions can drop, and snowfall may occur at times.

Quick Climate Overview

Season	Months	Average Temperature	Crowed Level	Best For
Spring	March-May	12–25°C	Low to Medium	Sightseeing, hiking, photography
Summer	June-August	25-35°C	Very High	Beaches, nightlife, island hopping
Autumn	September-Novmber	15–30°C	Medium	Couples, swimming, relaxed travel

Travel Tip: If you’re visiting Greece for the first time, May, June, September, and early October offer an excellent balance of pleasant weather, manageable crowds, and comfortable sightseeing.

Why the Month You Choose Matters

Many travelers think that the weather across Greece remains the same all year round, but that is not the case. In reality, your experience depends heavily on when and where you visit.

For example:

• Santorini in August is vibrant but crowded.
• The same island in late September offers warm weather with fewer tourists.
• Crete remains comfortable for beach holidays even into October.
• Athens is ideal in spring and autumn when temperatures are milder for exploring historical sites.
• Northern Greece, including destinations like Meteora, is especially scenic during spring and autumn.

Choosing the right month can help you save money, avoid long queues, and enjoy a more relaxed vacation.
