Weather in Tallinn, Estonia

Weather — Tallinn

Tallinn experiences a true Northern European climate: cold, snowy winters and mild, often pleasantly cool summers. If you’re booking flights or planning city breaks, expect long, luminous days in June and short, atmospheric daylight in December — and pack layers year‑round. Rain and drizzle are regular through the year, while the Baltic Sea keeps summer swimming brisk rather than tropical.

Weather — Tallinn January

January is one of the coldest months: daytime highs are usually around freezing or a little below, with nights commonly dipping into the minus range. Snow is frequent, creating a classic winter scene in the Old Town — ideal for cozy indoor activities, Christmas markets, and winter photography, but bring warm, wind‑proof clothing.

Weather — Tallinn February

February stays wintry with similar temperatures to January and regular snow cover. Days slowly lengthen and there are occasional clear, crisp spells — good for winter walks or enjoying café culture after exploring the city, though expect cold winds off the sea.

Weather — Tallinn March

March is a transition month: temperatures start climbing above freezing during the day but nights can still be frosty. Snow cover becomes patchy, and you’ll notice more variability — some sunny early spring days mixed with wet, chilly interludes.

Weather — Tallinn April

April brings clear signs of spring with milder days and rising daylight hours. Expect cool mornings and pleasantly warmer afternoons; rain showers are common but the city begins to feel livelier, making it a good shoulder‑season choice for sightseeing without peak summer crowds.

Weather — Tallinn May

May is reliably springlike: daytime temperatures often reach the mid‑teens Celsius and gardens start to bloom. It’s an attractive month for visitors who want milder weather and longer evenings — occasional rain persists, so a light waterproof and layers are sensible.

Weather — Tallinn June

June ushers in long, bright days (some of the longest of the year) and comfortable, mild temperatures ideal for exploring on foot. While rainfall can be higher than in late spring, you’ll enjoy pleasant outdoor conditions and festival season energy across the city.

Weather — Tallinn July

July is the warmest month with average highs in the low 20s°C — warm enough for sightseeing and outdoor cafés, though the Baltic Sea remains cool. This is peak summer for daylight and events; expect occasional showers but generally favourable conditions for travel and photography.

Weather — Tallinn August

August stays summery and mild with similar temperatures to July and the warmest sea temperatures of the year. It’s a great time for coastal walks and late‑evening outings, though August can also bring some of the year’s higher rainfall totals, so plan a flexible itinerary.

Weather — Tallinn September

September cools down but often offers pleasantly warm days and crisp evenings — an excellent month for combining city sightseeing with short excursions to nearby nature. Rain becomes a bit more frequent, and you’ll notice the first signs of autumn colours later in the month.

Weather — Tallinn October

October brings distinctly autumnal weather: cooler temperatures, shorter days and more wind and rain. It’s atmospheric for museums, cosy restaurants and enjoying autumn in the parks, but be prepared for blustery conditions and occasional wet spells.

Weather — Tallinn November

November is crisp and increasingly cold, with rising chances of sleet and early snow toward the end of the month. Daylight is limited, which adds a moody charm to the city — perfect for cultural trips, though you’ll want warm layers and waterproof footwear.

Weather — Tallinn December

December is wintery and often snowy, with short daylight hours and chilly temperatures. The festive season brings markets and a picturesque Old Town under snow; travel is atmospheric but dress warmly and allow time for winter transport changes.
