Climate Characteristics of Pärnu

General Overview

Pärnu is situated on the shores of Pärnu Bay in the northeastern Baltic Sea. Due to the bay's shallow waters, Pärnu enjoys the warmest sea temperatures in Estonia and the rest of the Baltic states during summer. Its climate is maritime-temperate, characterized by relatively mild winters compared to the interior and sunny summers that make it the country's primary resort destination.

Temperatures and Daily Variations

In summer, daytime temperatures average between 21°C and 24°C (70-75°F), and the sea breeze keeps the air pleasant and fresh. In winter, the average daytime temperature is around -1°C (30°F), dropping to -6°C (21°F) at night. Due to the proximity to water, winter cold is less extreme than in Tartu, but the humidity and sea winds can make the cold feel "wet" and piercing.

Precipitation Seasons (August-December)

Autumn is the rainiest season in Pärnu. The combination of relatively warm water and cold air arriving from the north often creates spectacular autumn storms and prolonged rainfall. In winter, snow is common but often alternates with freezing rain due to the maritime influence, creating slippery ground conditions.

Dry and Comfortable Seasons (May-July)

This is the city's golden period. May and June are the sunniest and driest months. During this time, the water begins to warm rapidly, and long days allow for many hours spent outdoors. Humidity is lowest in June, making the weather perfect for walking and cycling.
