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.

Weather in Tallinn by Month

January

The coldest month. Daytime temperatures are around -3°C (27°F) and drop to -9°C (16°F) at night. The city is snowy and the gulf is often partially frozen. Days are very short, but the city looks magical under the snow.

February

Deep, snowy winter. -2°C (28°F) daytime. Strong winds from the gulf make the cold feel much more intense. Snow usually reaches its maximum depth during this month.

March

The start of the thaw. 2°C (36°F) daytime. The sun begins to appear more, but the air is still very cold. It is a transition month where harbor ice begins to break and days lengthen significantly.

April

Spring arrives slowly. 9°C (48°F) daytime. Snow disappears and the city starts to dry. Weather is very volatile—late snow flurries are possible alongside bright, sunny days.

May

The month of blooming and awakening. 15°C (59°F) daytime. The skies are clear and the air is very fresh. Humidity is low, making it one of the best months for walking tours before the summer crowds.

June

The month of "White Nights." 19°C (66°F) daytime. The sun barely sets, and the atmosphere in the city is festive. The weather is very comfortable, though light rains are possible.

July

The warmest month. 22°C (72°F) daytime and 13°C (55°F) at night. Very warm and pleasant days. Ideal for sitting in outdoor cafes, though afternoon summer showers may occur.

August

Continuation of summer with 21°C (70°F). The sea is at its warmest (though still refreshing). Rainfall starts to increase, and nights become slightly more humid and cool.

September

Start of the colorful autumn. 16°C (61°F) daytime. Trees in the parks change color. The air becomes crisp and cool, and sea winds start to strengthen again.

October

Cooling and autumn winds. 10°C (50°F) daytime. Days shorten rapidly and skies become greyer. This is a rainy and windy month, signaling the near arrival of winter.

November

A dark and grey month. 4°C (39°F) daytime. There are almost no sunshine hours. Cold rains and heavy sea fogs are common. Chance of first snow toward the end of the month.

December

Winter returns. -1°C (30°F) daytime and -5°C (23°F) at night. The famous Christmas market opens in Town Hall Square, and the city is filled with festive lights reflecting in the fresh snow.
