What's the weather like in Tallinn by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Tallinn during Jun–Aug?
The peak season — warm, long, and lively. June has near-white nights with 18+ hours of daylight.
Shoulder season (May, Sep) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Apr, Oct–Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
