Weather in Pärnu

To ensure your trip is as comfortable as possible, check the current weather situation in Pärnu. Below you will find the latest data, charts, and forecasts to help you plan your day.

The climate in Pärnu can be described as temperate maritime, which is typical for coastal cities in Estonia. The proximity of the Baltic Sea plays a key role: it moderates temperature fluctuations, preventing extreme frosts in winter and exhausting heat in summer. The change of four seasons is clearly visible here, allowing tourists to enjoy diverse landscapes depending on the time of year.

Summer in Pärnu is undoubtedly the most popular season, when the city lives up to its title as the country's summer capital. During the warm months, especially in July and August, the average temperature stays at a comfortable level of about +17...+22°C, which is ideal for a holiday. Winter here is quite mild, with average values slightly below freezing (around -2°C), although humidity can intensify the feeling of cold.

A characteristic feature of the local weather is its variability and relatively high humidity. Precipitation is distributed relatively evenly throughout the year: even at the height of summer, rainy days are possible (on average 11–16 days with precipitation per month). Travellers should be prepared for a fresh sea breeze and carry an umbrella or windbreaker so that the whims of the weather do not interfere with walks around this cosy resort town.

The climate in Pärnu is characterized by distinct seasonality, typical of the Baltic region. The winter period here is moderately frosty: the coldest months are January and February, when the average air temperature stays at the level of -2.3°C...-2.4°C. At this time, night frosts can reach an average of -4.8°C, but during the day the thermometer often rises to the zero mark, making winter quite mild but snowy.

The summer season in Pärnu, considered the summer capital of Estonia, offers travellers comfortable and pleasant weather without extreme heat. The warmest month is traditionally July, with an average temperature of about 17.7°C and daily maximums reaching 21.9°C. June and August also delight with warmth, warming up during the day to 21.3°C, which creates ideal conditions for walks and relaxation on the coast, while avoiding exhausting heat.

It is worth considering daily temperature fluctuations, which are especially noticeable in the warm season. Even at the height of summer, the difference between daytime warmth and nighttime coolness can be about 8 degrees: after a comfortable 22°C during the day, the air cools down to 13.5°C at night. Spring arrives gradually, becoming truly pleasant by May (up to 16.3°C during the day), and autumn brings a smooth decrease in temperatures, remaining relatively warm in September.

Precipitation in Pärnu falls quite evenly throughout the year, but its character changes significantly depending on the season. In winter, when average temperatures stay below freezing (in January and February around -2.4°C), rain gives way to snowfall. January can be called one of the months most saturated with precipitation: snow or sleet falls often, averaging about 16 days per month.

Spring brings a relative lull. April and May are considered the driest period of the year, when the number of rainy days drops to 10 per month. This is the time when nature wakes up, and the probability of prolonged precipitation is minimal, making the spring months pleasant for walking around the city.

Summer, despite the warmth, can be quite humid in Estonia. In July, the frequency of precipitation increases again, reaching winter figures (about 16 days with rain), and in August it rains for approximately two weeks. In autumn, the weather remains overcast and damp: in October and November, about 13 days with precipitation are recorded, which gradually changes from rain to snow towards the end of the season.

The weather in Pärnu, as in all of Estonia, can be quite changeable, so the main principle when packing a suitcase is layering. Since the city is located on the coast of the Baltic Sea, it is often windy here, and a fresh sea breeze is felt even on warm days. Regardless of the season, be sure to take a windbreaker or jacket that will protect you from the wind. Comfortable and, preferably, waterproof shoes will become your best friend, as walking along the beach, parks, and ancient streets is an integral part of a holiday at this resort.

If you are planning a trip in summer, when the air temperature comfortably stays around +20...+22°C, stock up on light clothes made of natural fabrics and swimwear, but for evening promenades, be sure to grab a warm sweatshirt or cardigan. In winter and the off-season, when the temperature drops below freezing, you will need a reliable down jacket, hat, scarf, gloves, and warm shoes with thick soles to enjoy walks without the risk of freezing.

Precipitation in Pärnu is possible at any time of the year: statistics show an average of 10 to 16 rainy days per month. Therefore, a compact umbrella or a quality raincoat should always be in your luggage. Also, do not forget about sunscreen and sunglasses during the summer period, as the sun near the water can be quite active, even if the heat does not seem exhausting.
