Evia in summer

Evia in September and October
September is excellent: 19–28°C with a warm sea. October is cooler (15–22°C) and the rains begin, but it is a good time for mountain walks and the Edipsos hot springs, which run all year.
Evia in winter and spring
Winter is 9–15°C in Chalkida, and the high mountains such as Dirfys can see snow. Spring (April–May) is green and in bloom at 12–26°C, though the sea is still cold for most people.
