Tallinn Estonia weather swings a lot across the year. Summer brings long, bright days. Winter brings short, snowy afternoons instead. Packing right for the season makes a real difference to any trip here.

Tallinn's warmest month is July. Highs sit in the low twenties Celsius, with long daylight hours. Winter brings regular snow from December through February. Spring and autumn call for layers and a waterproof jacket, given how fast conditions shift.

Summer Tallinn Estonia weather

June through August brings the mildest, driest weather of the year. Highs typically sit in the high teens to low twenties Celsius. Days stay long, with light well into the evening. Summer works as the easiest season for a relaxed, unhurried visit.

Winter Tallinn Estonia weather

December through February brings cold air and regular snow. Temperatures often sit below freezing for stretches. This is also when the Old Town's Christmas market runs. You trade warmth for a distinctive seasonal mood.

Spring and autumn weather

Both shoulder seasons bring changeable weather. Mild, sunny stretches can shift to cold, wet days within the same week. Layers and a waterproof jacket handle this better than one heavy coat.

Packing for Tallinn's weather

A light jacket suits most summer evenings. Temperatures drop after sunset even in July. Winter visitors need a proper coat and warm layers. Waterproof boots help too, given the snow and ice on cobblestone streets.

Rain patterns across the year

Rain spreads fairly evenly across the year in Tallinn. There is no single, clearly defined wettest month. Late summer and early autumn tend to see slightly more rain on average than the other seasons of the year. A light rain jacket or a small folding umbrella covers most trips well enough. This holds regardless of the specific month visited.

Daylight hours through the seasons

Summer daylight stretches remarkably long here, with the sun barely setting around the summer solstice in late June each year. Winter flips this pattern completely, with short days and early sunsets by mid-afternoon throughout December and January each year. This swing affects sightseeing planning more than temperature does for some visitors. Winter daylight cuts outdoor time a lot. Plan indoor things for the dark afternoons on a winter trip.

How Tallinn's weather compares with nearby cities

Tallinn's weather is much like Helsinki's, just across the Gulf of Finland. Both cities sit on the coast at about the same latitude. It runs slightly milder than Riga or Vilnius in deep winter, thanks to the sea's moderating effect on temperature extremes. This makes Tallinn a marginally gentler winter destination overall, compared with its two inland neighboring Baltic capitals to the south.

Any single year can still run warmer, colder or wetter than the normal, so check a forecast close to your trip. In winter, Tallinn's Christmas market has a longer season this year. Its official site lists 20 November 2026 to 6 January 2027.

Since 12 October 2025, the EU's Entry/Exit System (EES) has registered non-EU citizens on short stays when they cross the Schengen external border. It records passport details, fingerprints and a facial image, and it replaces passport stamps. The European Commission says it has run at all Schengen borders since April 2026.
