Weather in Kuressaare: What to Expect by Season

Winters here are quiet, with temperatures often hovering around 0.3 °C in January and February, while summers bring warmth without extremes—July and August average 18.4 °C and 18.2 °C, respectively. The shoulder seasons, April to May and September to October, offer a mix of crisp air and fewer crowds, making them ideal for exploring the town’s coastal charm.

The weather in Курессааре rarely surprises with sudden shifts, but rain can appear year-round. August and October are the wettest months, with over 70 mm of precipitation each, while March and April tend to be drier. Even in summer, a light breeze off the sea keeps the air fresh, and the long daylight hours in June (up to 12.4 hours of sunshine) invite leisurely walks along the promenade or through the medieval castle grounds.

Autumn in Курессааре cools gradually: September still holds onto 14.6 °C, but by November, temperatures drop to 5.1 °C, and December brings a return to near-freezing conditions. The sea mirrors this pattern, warming to 20.6 °C in July but cooling to 0.6 °C by January. For travelers, this means packing layers—even in summer, evenings can feel cool, especially near the water.

Snow is rare in Курессааре, but light flurries can occur in December or January, usually melting quickly. The town’s coastal location means humidity is a constant, though it’s rarely oppressive. For those visiting in June or September, the balance of mild temperatures and moderate rainfall makes these months particularly pleasant for outdoor activities, whether it’s cycling through the countryside or visiting the local spas.

For a winter trip to Курессааре, pack warm layers: a insulated jacket, gloves, and a hat will help against the damp cold, especially in January and February, when temperatures hover near freezing. Waterproof boots are useful year-round, but particularly in October and November, when rain is more frequent. Even in summer, a light sweater or windbreaker is wise for breezy evenings, especially if you plan to spend time near the sea.

In June or July, when temperatures reach 18–20 °C, lightweight clothing is ideal, but don’t forget a scarf or shawl for cooler mornings. If you’re visiting in May or September, layers are key—days can start at 7–10 °C but warm up to 15–17 °C by afternoon. A compact umbrella or a waterproof jacket will come in handy during the wetter months, while sunglasses and sunscreen are essential in June and July, when the sun shines for over 11 hours a day.
