When to Visit Estonia, Latvia and Lithuania: Weather by Month
When Is the Best Time to Visit the Baltic States?
June to August is the warmest and brightest time to visit the Baltic States, with daytime highs typically between +19 and +25 °C. May and September are the calmer shoulder months, mild enough for long walks but cooler once the sun goes down. Which window suits you depends on the trip you have in mind. Beach time at Pärnu or on the Curonian Spit points to July or August, when the sea and lakes are at their warmest. If you’re coming mainly for the Old Towns, May or September tends to be more comfortable on foot.
The Baltic climate is temperate, somewhere between maritime and continental. Winters are mild and summers humid rather than hot. The figures below are regional ranges, not readings for any one city, so treat them as a guide to typical conditions rather than a promise. Spring and autumn are the least predictable seasons, with March unstable and September cooling fast toward its end.
Spring in the Baltic States: March, April and May
Spring in the Baltic States is a season of fast change. March often still feels wintry, yet by May the trees are green and the first properly warm days have arrived. The 8-day Baltic Highlights group tour has weekly departures from March 21 to October 10 in 2027, so its season opens while the snow is still melting.
If you want mild weather without summer conditions, aim for late April or May. Earlier in the season, expect cold mornings and slushy streets. March and early April suit city breaks better than the coast or the national parks, since melting snow and cold nights limit time outdoors.
March in the Baltic States
In the Baltics, March is early spring and the weather is unsettled. Daytime temperatures usually reach +3 to +5 °C, but nights still fall to between −2 and −4 °C. As the snow cover melts, waterproof shoes make city walking far more pleasant.
April in the Baltic States
April brings genuine spring warming to the Baltic States, along with relatively little rain. Expect days of around +8 to +10 °C and nights close to 0 to +2 °C. Layers will see you through a day of Old Town sightseeing.
May in the Baltic States
May is when the favorable travel season begins in the Baltics. Days generally sit at +15 to +18 °C, occasionally touching +20 °C, while nights drop to about +5 to +8 °C. With the countryside turning green and sunshine hours lengthening, it’s a good month for Lahemaa and Gauja national parks.
Summer in the Baltic States: June, July and August
Summer is the warmest and brightest season in the Baltic States, and the best one for the coast. The sea and lakes warm gradually through June and are at their warmest in August. Among escorted Baltic tours with fixed dates, the 14-day Grand Baltic Adventure is timed around this window, with 2027 departures from May 28 to September 3.
Nights stay mild throughout a Baltic summer, typically +11 °C or higher from June to August. That makes evenings outdoors easy to plan, whether in an Old Town square or by the sea. July combines the highest temperatures with more frequent showers, so a flexible day or two in the plan helps.
June in the Baltic States
June has the longest days of the Baltic year, with more than 17 hours of daylight. Daytime highs are usually +19 to +21 °C, though hotter spells happen, and nights hover around +11 to +13 °C. The water is only starting to warm, so June favors long evenings in town over full beach days.
July in the Baltic States
July is the warmest Baltic month, with days typically at +22 to +24 °C and peaks above +28 °C. Nights stay around +12 to +15 °C. This is peak beach season at Pärnu and on the Curonian Spit, but also a wetter month, so carry a light rain jacket for the short showers.
August in the Baltic States
August stays close to July in the Baltics, with days of about +21 to +25 °C and nights of +12 to +14 °C. The sea and lakes are at their warmest, which makes it the best month for a swim near Nida. Toward the end of the month, though, the weather starts to feel like early autumn.
Autumn in the Baltic States: September, October and November
Autumn in the Baltic States begins mild and ends gray and damp. September is still a good month to travel, especially early on, but by October the wind and rain set the tone.
Temperatures fall steadily through a Baltic autumn, from days of up to +20 °C in early September to around +4 to +5 °C in November. Whichever month you choose, pack a waterproof layer, because September brings more rainy days and the later months are damp.
September in the Baltic States
September is golden autumn in the Baltic States. Early in the month, days typically reach +16 to +20 °C and nights sit around +8 to +10 °C, but it turns noticeably colder by the end. Rainy days become more frequent, so leave some flexibility in any plans for the national parks.
October in the Baltic States
October in the Baltics tends to be gloomy and windy, with days of +8 to +12 °C and nights of +2 to +5 °C. Leaves fall and humidity rises. A city break built around indoor sights works well, while the coast and long hikes are much less rewarding.
November in the Baltic States
November is late autumn in the Baltic States, damp and overcast for much of the month. Days hover around +4 to +5 °C and nights near 0 to −1 °C, with rain often mixed with snow. If you travel now, base yourself in one Old Town and keep your time outdoors short.
Winter in the Baltic States: December, January and February
Baltic winters are cold and gray, though the climate keeps them mild rather than harsh. Temperatures stay close to freezing on the coast and drop lower inland, and snow is never a given.
A winter route through the eastern inland areas of the Baltics will feel colder than one that stays near the sea. Short outdoor stretches and a few indoor fallbacks make the season much easier to manage.
December in the Baltic States
December brings short days to the Baltics, with daytime temperatures around 0 to +1 °C and nights of −3 to −5 °C. Lasting snow cover doesn’t always form, and whether it does depends on the sea. Don’t plan a December trip around snow.
January in the Baltic States
On the Baltic coast, January typically sits at 0 to −3 °C, while eastern inland areas can fall to −5 to −8 °C. Skies are often overcast and damp, and you may get snow or a thaw with rain. Warm layers and waterproof boots matter more than a fixed itinerary.
February in the Baltic States
February in the Baltic States looks much like January, with days around 0 to −3 °C and nights down to −5 to −9 °C. Snow and winter winds are common, and the wind makes long walks tiring. Short stretches outdoors between cafés and museums suit the month best.
Which Baltic Month Suits Which Type of Trip?
For city walking, May and September are the most comfortable months in the Baltic States. For the coast, go in July or August, when the sea and lakes are warmest.
The UNESCO-listed Old Towns of Tallinn, Riga and Vilnius are best seen on foot, and days of around +15 to +20 °C make that easy. June suits walkers too, thanks to its long evenings. Trip length shapes the plan as much as the month does, and a separate guide explains how to plan 7, 10 or 14 days in the Baltic States and divide the time between cities.
April and October can also work for Old Town walks if your dates are fixed. With days of roughly +8 to +12 °C, you’ll need clothing for wind and rain rather than sunscreen.
Swimming at Pärnu or on the Curonian Spit is best in July or August, although July brings more rain, usually in short showers. August is the safer bet for a swim, because that’s when the water is warmest. In June the water is only starting to warm, so beach walks are more realistic than swims.
To combine city sightseeing with time on the coast, June is the most balanced choice in the Baltics. Warm days and long evenings leave room for both.
Lahemaa and Gauja national parks are at their best between May and early September. May brings fresh green and growing sunshine hours, and September adds autumn color, though with more rainy days. From October, the wet and windy weather makes park visits far less appealing.
If avoiding crowds matters more than warm weather, the shoulder months of May and September are the usual choice for a Baltic trip. You trade a few degrees of warmth for a slower pace in the Old Towns.
Winter in the Baltic States works best as a short city break. Between December and February, an Old Town base keeps cafés and museums within reach on overcast, damp days.
Coast vs. Inland: How Baltic Weather Differs
The Baltic coast is milder and windier, while inland areas are more continental, with colder winters and warmer summers. January shows the difference clearly, with the coast typically at 0 to −3 °C and eastern inland areas down to −5 to −8 °C.
In summer, inland areas of the Baltics tend to feel warmer than seaside towns. On the coast, wind changes how a day feels, and a breezy afternoon in Pärnu or Nida can seem cooler than the forecast suggests. Pack a spare layer, even in July.
For a winter trip, the gap between coast and inland is worth factoring into the route. A seaside stop in Pärnu or on the Curonian Spit is usually less cold than a day in the eastern inland, though it will be windier.
Humidity also shapes the Baltic climate. Summers are humid rather than hot, and winter days are often overcast and damp, which can make temperatures near freezing feel raw. In summer, the same humidity can make a warm afternoon feel muggier than the number suggests.
Every temperature in this guide is a regional range for the Baltic States as a whole, not a figure for Tallinn, Riga or Vilnius individually. Check a local forecast a few days before you travel, particularly if your route includes the coast.
