Traveller notes on Plitvice Lakes in September
Notes from nearby Zagreb (110 km away)
Plitvice Lakes doesn't have its own notes for September yet — these are about Zagreb, close enough to share the season.
Croatia's forum calls September generally the best month to visit the country, still warm — inland cities like Zagreb hold onto the heat longer than the coast starts to cool. Regulars caution the pattern isn't guaranteed: one memorable September ran cool and rainy for two weeks, so a rain layer is worth packing alongside summer clothes.
Other months in Plitvice Lakes
Plitvice's forum calls June generally good, with real crowds not building until mid-July. Regulars note the park's weather can still turn changeable — one visitor's June trip brought torrential rain that had actually been falling in the mountains for days, which made the waterfalls especially dramatic rather than ruining the visit, and the lakes reportedly carry more water in June than later in summer.
