Climate Characteristics of Tallinn
General Overview
Tallinn is situated on the coast of the Gulf of Finland in northern Estonia. Its climate is significantly influenced by the sea, which acts as a temperature regulator: it delays the onset of summer but also moderates the extreme cold of early winter. The Old Town of Tallinn, with its spires and cobblestone streets, takes on a completely different character in each season—from a bustling, sunny port in summer to a fairytale city covered in white snow in winter.
Temperatures and Daily Variations
In summer (July-August), daytime temperatures range between 20°C and 23°C (68-73°F), making it an ideal time for walking tours. In winter, the average daytime temperature is around -2°C (28°F), dropping to -8°C (18°F) or lower at night. Due to its northern latitude, there is a dramatic shift in daylight hours: at the peak of summer, the sun barely sets ("White Nights"), while in mid-winter, there are only about 6 hours of daylight.
Precipitation Seasons (August-November)
Autumn is the rainiest and windiest period in Tallinn. Light but prolonged rains and sea fogs are very common. In winter, precipitation turns into stable snow that covers the red-tiled roofs of the Old Town. Winds from the gulf can be very strong, especially in the harbor area.
Dry and Comfortable Seasons (May-June)
Late spring and early summer are the driest and brightest months. This is when the city "wakes up"; parks (like Kadriorg Park) are green and blooming, and humidity is relatively low. This is the most recommended time for those who want to experience Tallinn in full daylight and stable weather.
