Traveller notes on Halkidiki in May

Notes from nearby Thessaloniki (79 km away)

Halkidiki doesn't have its own notes for May yet — these are about Thessaloniki, close enough to share the season.

Thessaloniki's forum rates May as warm and sunny by day, genuinely cool once the sun sets — good weather for sightseeing rather than the beach. Regulars are consistent that the sea itself stays too cold to swim comfortably until later in the summer, whatever the air temperature suggests.
