Weather in Kemi

Find out what weather awaits you in Kemi right now and in the coming days. Here, we have gathered up-to-date summaries, charts, and forecasts for the comfortable planning of your journey.

The climate of the city of Kemi can be described as subarctic, with distinct seasonality typical of northern regions. The weather here is dictated by its proximity to the Arctic Circle and the influence of the Bothnian Bay: winters are long, snowy, and frosty, while summers are short and moderately warm, creating a unique atmosphere for travel at any time of the year.

The longest season is winter, which lasts from November to April. During this time, temperatures consistently stay below zero, dropping to an average of -9°C in the coldest months, creating ideal conditions for the region's famous ice castles. Summer, by contrast, is mild and fresh: in July and August, the air warms up to a comfortable +15...+17°C, allowing you to enjoy nature without exhausting heat.

A characteristic feature of the weather in Kemi is the fairly stable number of days with precipitation throughout the year. Whether it is winter snowfall or autumn rain, cloudy or humid days are not uncommon here, so tourists should ensure they have appropriate clothing. Despite the severe nature of the northern environment, the absence of extreme temperature jumps within a single season makes the climate quite predictable for planning a trip.

The climate in Kemi is distinguished by a pronounced northern character with frosty winters and cool, fresh summers. The coldest period of the year is January and February, when average indicators drop to -8.3°C...-8.7°C, and during the night hours, they often reach -11°C. Sub-zero temperatures set in as early as November and persist almost until the end of April, so high-quality warm equipment is essential for a winter trip to this region of Finland.

The summer season here is mild and comfortable, without sweltering heat. The peak of warmth occurs in July: in this month, the air warms up on average to +16.6°C, and daytime maximums closely approach the +20°C mark. June and August are slightly cooler, with temperatures around +13...+15°C, which is ideal for tourists who prefer a moderate climate.

Daily temperature fluctuations in the city are relatively small. The difference between day and night readings is usually about 4–7 degrees, making the change of time of day smooth. Spring arrives gradually: while frost still rules in March (around -5°C), by May the air warms up to +6°C, marking the definitive arrival of warmth.

The character of precipitation in Kemi is closely linked to seasonal temperature changes typical of northern Finland. The winter months, from November to March, bring stable snowfall, as the air temperature stays below zero. In December and January, it snows quite often—on average from 11 to 14 days per month, covering the city in a dense white blanket.

Spring is the driest period of the year. April stands out in particular, when the number of days with precipitation drops to a minimum (about 7 days), and their intensity is low. This is a transitional time when the snow begins to melt, but heavy rains are not yet characteristic of the region, making mid-spring relatively comfortable for walking.

Summer and early autumn are the times of highest humidity. The number of rainy days increases noticeably, peaking in August and October, when precipitation can fall for up to 15 days a month. During this period, rains are often prolonged, so travellers are recommended to carry an umbrella and waterproof clothing, especially if the trip is planned for the end of the tourist season.

A journey to Kemi requires a careful selection of your wardrobe, as the weather here bears a true northern character. In winter, when the temperature drops significantly below zero, the foundation of your comfort will be high-quality thermal wear, wool sweaters, and windproof outerwear. Be sure to bring a warm hat, a scarf, and mittens, as well as winter shoes with thick soles, to enjoy walks through the snowy city without the risk of freezing.

Summer in this region of Finland is mild but rarely hot, so even in July and August, it is worth sticking to the principle of layering. A light windbreaker jacket or a fleece top will come in handy for cool evenings and windy days on the coast. We recommend having long-sleeved t-shirts and jeans with you, which will ensure comfort and modesty during the changeable weather characteristic of the off-season and summer months.

Regardless of the season, practical accessories will be useful on your trip. Considering that precipitation is a frequent occurrence here (up to 15 rainy or snowy days per month), a compact umbrella or raincoat will become your faithful companions. For exploring city attractions, choose comfortable waterproof shoes suitable for long walks. Also, do not forget sunglasses: in winter, they will protect your eyes from the bright light reflecting off the snow, and in summer—from the long polar day.
