The climate of Halden can be described as temperate, with distinct seasons typical of southern Norway. The weather here is rarely extreme: winters are quite mild for Scandinavian latitudes, with average temperatures around freezing or slightly below, while summers offer pleasant warmth without sweltering heat.

The summer months, especially July, bring the most pleasant weather, with air temperatures averaging 21°C. This is an ideal time for long walks and outdoor sightseeing. However, travelers should keep in mind the unpredictability of the weather: even in the height of summer, precipitation is possible, as the number of rainy days during this period remains quite high.

Spring arrives in the city gradually, and April often turns out to be one of the "driest" months of the year, making it a good option for traveling during the shoulder season. In autumn, temperatures gradually drop and the number of cloudy days increases, creating an atmospheric but chilly setting before the onset of winter.

The temperature regime in Halden is characterized by the moderation typical of southern Norway, without extreme fluctuations. The winter period here can be described as mild and slightly frosty: the coldest months are January and February, when the average temperature stays around -0.2°C to -0.9°C. Night frosts occur regularly, dropping the mercury to -3.0°C, but during the day, the air often warms up to positive values, making winter quite comfortable for a prepared tourist.

Summer in the city brings pleasant warmth but not sweltering heat, which is ideal for active recreation. The warmest month is July, when daytime highs reach an average of 21.0°C, and the average temperature is about 17.1°C. June and August also offer mild weather with figures around 16°C. This time of year is characterized by freshness and comfort, allowing you to enjoy nature without needing to seek shelter from the heat.

When planning your trip, it's important to consider daily temperature fluctuations, which are most noticeable in the summer season. The difference between daytime warmth and nighttime cool can be about 8 degrees: after a sunny day with a temperature of +20°C, the air can cool down to +12°C at night. In transitional seasons such as April and October, the temperature background is more stable but still requires warm clothing for evening walks.

Precipitation in Halden is distributed unevenly throughout the year, creating noticeable differences between the seasons. The winter months, especially December, January, and February, are characterized by temperatures around freezing or slightly below, so moisture often falls as snow, creating picturesque winter landscapes. December stands out with a high frequency of precipitation — about 15 days per month — which is worth considering when planning a trip during the holiday season.

Spring brings the most stable and dry weather. April is the "driest" month of the year: the number of days with precipitation drops to an average of 8, and the volume becomes minimal. March also features a relatively low number of rainy days. This time of year is excellent for those who want to avoid the damp and enjoy outdoor walks.

In contrast, summer and early autumn can be quite wet. From June to September, the frequency of rain increases, peaking in August when about 15 days of precipitation are recorded. July also sees a higher volume of moisture. Summer rain is common in this region of Norway, so even during the warm season, travelers are strongly advised to carry an umbrella or a raincoat.

When heading to Halden, it's important to remember that Norwegian weather can be unpredictable, so the main principle when packing is layering. In winter, temperatures often hover around freezing, so be sure to bring thermal base layers, wool sweaters or fleece jackets, and a windproof winter jacket or down coat. Given the high humidity and frequent precipitation in winter, warm waterproof footwear with non-slip soles is essential, as are a hat, scarf, and gloves to protect against the wind.

Summers in Halden are usually mild and comfortable, with average temperatures around +16°C...+17°C, though extreme heat is rare. Even in July and August, evenings can be cool, so a light jacket, windbreaker, or jumper is a must in your luggage. Statistics show that rainy days occur regularly throughout the year (up to 15 days a month in summer), making a quality raincoat a more practical choice than an umbrella, which can be awkward in gusts of wind. In spring and autumn, the weather is particularly fickle, so be ready to layer up or down quickly.

For walking around the city and its surroundings, including climbs to attractions, you'll need comfortable shoes, such as sturdy sneakers or trekking boots. Despite its northern location, the sun can be strong, especially in late spring and summer, so don't forget sunglasses and sunscreen. A small backpack will also come in handy for carrying water and extra layers of clothing in case of a sudden change in weather.
