Kuressaare weather forecast for 5 days

Climate Characteristics of Kuressaare

General Overview

Kuressaare is located on the shores of the Gulf of Riga in the southern part of Saaremaa Island. Due to its position on an island in the heart of the Baltic Sea, its climate is the most maritime in Estonia. The sea acts as a massive "thermal battery": it stores heat in summer and releases it slowly in winter. Consequently, winters in Kuressaare are the mildest in Estonia, and spring arrives later than on the mainland as the surrounding cold sea delays the warming of the air. The city is famous for its impressive Bishop's Castle and its clean, healthy air.

Temperatures and Daily Variations

In summer, daytime temperatures average between 20°C and 23°C (68-73°F). Due to the constant sea breeze, it is almost never too hot. In winter, the average daytime temperature is around 0°C (32°F) or slightly above, with nights hovering around -3°C (27°F). This is a significant difference compared to frozen eastern Estonia. Day-to-night temperature variations are the minimal in the country thanks to the moderating influence of the water surrounding the island on all sides.

Precipitation Seasons (September-December)

Autumn is the dominant season for precipitation and wind. Baltic sea storms are common during this period, and humidity is very high. In winter, snow falls, but due to relatively moderate temperatures, it often melts or falls as freezing rain more frequently than in Tallinn or Tartu. Natural sea ventilation maintains high air quality but creates a "wet" cold sensation.

Dry and Comfortable Seasons (May-July)

This is the island's most beautiful period. May and June are the sunniest months in all of Estonia (the islands enjoy more sun hours than the mainland). The skies are clear, and the cool sea prevents the formation of heavy rain clouds. It is an ideal time for birdwatching, hiking in the island's wild nature, and visiting the famous windmills under clear blue skies.
