Greece in May
Weather in Greece in May
If you're visiting Greece in May, you'll find average temperatures of around 20°C. Depending on where you are in the country, you'll enjoy warm sunny afternoons with highs of 26°C and evening lows of 14°C,
so perhaps bring a light jacket! The sea can still be a little chilly around May as it's yet to have the summer sun heat it up, but at 18°C, braver swimmers will still find the waters inviting.
