September weather forecast
Sweden

September in Sweden signals the transition from summer to autumn. The average temperatures begin to drop, ranging from 10°C (50°F) to 15°C (59°F) in the southern parts of the country and 5°C (41°F) to 10°C (50°F) in the northern regions. The decline in temperature is gradual, with the beginning of the month still experiencing relatively warm weather.

Daylight hours also decrease in September. Southern Sweden sees daylight for around 13 hours at the start of the month, decreasing to approximately 11 hours by the end. North of the Arctic Circle, the period of continuous night, known as Polar Night, doesn't begin until winter, allowing for considerable daylight during September.

September typically sees precipitation levels ranging from 40mm (1.57") to 60mm (2.36"). The occurrence of rain is evenly distributed throughout the month. While most days are dry and clear, the chance of rainfall increases as the month progresses.

Wind speeds during September generally range from 10km/h (6.2mph) to 20km/h (12.4mph). Higher gusts reaching 30km/h (18.6mph) can occur, especially in coastal regions and during stormy weather. The calm to moderate winds are suitable for outdoor activities such as hiking and bird watching.

In terms of natural beauty, September stands out as the beginning of the "ruska" period, when deciduous trees change colors, painting the landscape in vibrant shades of yellow, orange, and red. This spectacle is particularly noteworthy in the northern regions where vast birch forests adopt autumn hues.

September is also the start of the harvesting season for apples, and apple orchards become a popular destination. Meanwhile, the decrease in temperature and the commencement of the rainfall make it an ideal time for mushroom foraging in the forests.

Outdoor activities remain popular, especially hiking and cycling to witness the country's remarkable autumn foliage. However, the gradual drop in temperatures and shorter daylight hours suggest that visitors should pack layers and prepare for a variety of weather conditions.
