Athens in July

When to go

The WMO averages listed above point to hot days, warm nights and low rainfall in July, though they come from a past period, so treat them as a guide and not a forecast. Athens' official visitor guide places the Athens and Epidaurus Festival from the start of June to late August, so July falls inside it; check the festival's own programme for dates and venues. The Ministry of Culture's museum site lists summer-season hours for the National Archaeological Museum, and it is worth checking opening hours for every site on your list.
