Lithuania is at its best in high summer, from June to August, when the days are long, the nights are short, and the Baltic Sea’s waters are warm – or at least swimable. Festival season hits high gear: one not to miss is Klaipėda’s three-day Sea Festival.
Spring (April and May) is cool and arrives late but is good for canoeing, as the thawing snow feeds the rivers.
Autumn (September to November) can be ideal, with sunny days and chilly nights. Culture reaches a crescendo with classical music festivals and the annual Mama Jazz festival in Vilnius.
