The Latvian climate is cold and snowy in winter, and mild or pleasantly warm and quite rainy in summer. The coastal areas are a bit more temperate, but also more humid and windy, while the eastern area has a slightly more continental climate. The capital city, Riga, is located on the coast, but overlooks the Gulf of the same name that is closed and therefore receives a less pronounced maritime influence, so much so that in winter the sea can freeze.
Here are the average temperatures of Riga.

Winter in Latvia is cold, with gray skies, and frequent snowfalls, though not abundant. Moving towards the east, the temperature decreases: the average temperature of January and February is around -2 °C (28 °F) in Liepaja, on the west coast, of -3 °C (27 °F) in Kolka, at the entrance of the Gulf of Riga, and of -3.5 °C (25.5 °F) in Riga, while in Daugavpils and Kraslava, in the south-east, it reaches -5 °C (23 °F). In any case, the average temperatures are only the result of different situations: the western currents of Atlantic origin are damp but not cold, and can raise the temperature a few degrees above freezing (0 °C or 32 °F), while the cold air masses from Russia or from the Arctic may lower the temperature even below -20 °C (-4 °F); in the worst moments, the temperature can drop to about -35 °C (-31 °F).

Spring is quite late in Latvia: on early April, the country may still be under the snow. From mid-April, usually the temperatures become milder. In May the weather can still be cold, especially at the beginning of the month, but the temperature rises over the course of the month, exceeding even 20 °C (68 °F) in the warmest days.

Summer is a mild in coastal areas, with highs around 18/20 °C (64/68 °F), while it becomes slightly warmer in the interior, where the temperature reaches 20/22 °C (68/72 °F) during the day. Summer is also the rainiest season, especially in inland areas, where thunderstorms may occur in the afternoon. Sometimes, warm air masses from the south-east can raise the temperature, which can approach 30 °C (86 °F) for a few days.

In autumn, rains are frequent and the sky is often gray. The temperature gradually decreases: in October it's already cold and in November the first snowfalls occur.


For swimming, the Baltic Sea is cold: in the Gulf of Riga the sea temperature varies from 1 °C (34 °F) in February and March, to 16 °C (61 °F) in July and 17 °C (63 °F) in August, while on the west coast it is just warmer.

When to go

The best season to visit Latvia is summer, from June to August. The temperatures are mild during the day, and lend themselves to outdoor activities, while the nights are still cool. There's no shortage of rain, which occurs on average one day out of three.
If you want to visit the country in its winter look, February is preferable to December, because although it is even colder, it has longer days.

What to pack

In winter: very warm clothes, down jacket, hat, gloves, scarf.
In summer: clothes for spring and autumn, being ready to add or remove the outer layer, t-shirt, but also long pants, jacket and sweatshirt; raincoat or umbrella.
