Stay informed about the latest meteorological changes when planning a visit to the city of Kärdla. Here you will find the most up-to-date information on temperature and forecasts for the near future, ensuring your journey is as comfortable as possible.

The climate in Kärdla can be characterized as temperate maritime, which is typical for the island part of the country. Thanks to the influence of the Baltic Sea, there are no extreme temperature fluctuations here: winters are milder and summers are cooler than on the mainland. This makes the city a pleasant destination for those who find intense heat or severe frost difficult to tolerate.

Summer here is comfortable and fresh, with average temperatures in July and August around 18°C, which is ideal for long walks in nature. Winter months are characterized by temperatures around zero or slightly below, rarely dropping to extreme values. Spring arrives gradually, becoming noticeably warmer only by May, while autumn can be quite prolonged.

Tourists should take into account the high humidity and frequent cloudiness throughout the year. The number of days with precipitation remains significant even in the driest months, so an umbrella or raincoat will become faithful companions on your journey. The highest number of rainy days (up to 16 per month) occurs during the autumn-winter period, when the weather becomes windier and damp.

The climate in the city of Kärdla is distinguished by its noticeable mildness and lack of sharp changes, due to its location on the island of Hiiumaa. Thanks to the influence of the Baltic Sea, winters here pass without extreme frosts. The coldest months are traditionally January and February, when the average temperature hovers around the mark of -0.5°C... -0.7°C. Even during the night hours, the air rarely cools below -2.5°C, making the winter season cool and humid rather than severe.

Summer in this corner of Estonia can be described as moderately warm and very comfortable for travellers who do not enjoy strong heat. The peak warmth occurs in July and August, when average figures reach +18°C. During these months, the daytime temperature usually rises to +20.5°C, creating ideal conditions for strolling. Scorching heat is a great rarity here; pleasant freshness prevails.

A characteristic feature of Kärdla's temperature regime is the minimal difference between day and night figures. Throughout the year, the daily amplitude is only 3-5 degrees, and in summer, nights remain almost as warm as the days (around +15.5°C). Autumn arrives smoothly: September still delights with an average of +14°C, but by November the temperature drops to +5°C, heralding the arrival of winter.

When planning a trip to Kärdla, it is worth considering the changeable nature of the weather inherent to this region. Precipitation is distributed unevenly throughout the year, allowing you to choose the most comfortable time for outdoor walks.

The driest period can be considered spring and the beginning of summer. In May, April, and June, the number of days with precipitation is minimal — on average 7–8 days per month. This is the best time for those who prefer clear skies and dry weather for exploring the city.

The highest probability of rain or snow (depending on the season) falls on October and January, when up to 16 days with precipitation are recorded. August, despite the warmth, can also be quite rainy (about 15 days). Travellers are recommended to always have an umbrella or raincoat with them, as humidity and brief showers are frequent companions of the local climate.

Preparing luggage for a trip to this cosy Estonian city largely depends on the season, but the main rule here is layering. The weather on the island of Hiiumaa, where Kärdla is located, can be changeable due to the proximity of the sea, so even in summer, it is worth having warm clothes at hand.

In summer (average temperature +16...+20°C) you will need T-shirts, light trousers, and comfortable trainers for long walks along green streets and parks. Be sure to bring a windbreaker or fleece jacket: evenings can be cool, and the wind from the Baltic is fresh. Do not forget swimwear if you plan to relax by the coast.

In the off-season (spring and autumn), the weather is often rainy and windy. In October and November, the number of days with precipitation increases, so a high-quality raincoat and waterproof footwear become essential items. An umbrella may not always be convenient due to gusts of wind, so it is better to prefer a jacket with a deep hood.

In winter, the temperature usually holds around zero or dips slightly into the minuses. At this time of year, it is important to dress warmly: thermal underwear, woollen socks, insulated boots with non-slip soles, a hat, and gloves will make walks comfortable. Given the high humidity, the cold may feel stronger than the thermometer indicates.
