Traveller notes on Piran in June
Notes from nearby Ljubljana (93 km away)
Piran doesn't have its own notes for June yet — these are about Ljubljana, close enough to share the season.
Slovenia's forum calls June the start of real summer — warm days, though early mornings can still be cool, especially after rain. Regulars note the mountains run noticeably colder than Ljubljana itself, so a trip that mixes the capital with alpine hiking needs to pack for both.
