Weather in Fort Simpson

Stay informed about weather conditions when planning your trip to Fort Simpson. Below you will find up-to-date forecasts and detailed charts to help you prepare for your journey.

The climate in Fort Simpson can be described as subarctic, with distinct seasonal contrasts. This region is characterised by a long and severe winter, which is followed by a short but sufficiently warm and comfortable summer. The temperature range throughout the year is very significant here, so the nature of the weather depends directly on the month chosen for your holiday.

Winter sets in as early as November and lasts until March, bringing significant cold, with the average temperature often staying around -20°C and lower. The summer season, lasting from June to August, on the contrary, offers pleasant conditions for tourism: the air warms up to an average of +17...+19°C, and on the warmest days, temperatures can rise to +25°C—a refreshing change for travellers from the Gulf. Summer is the period with the highest amount of rainfall, with rain occurring for about 10–12 days per month.

Spring and autumn are quite fleeting here, serving as quick transition periods with sharp temperature changes. If you are planning a trip to this part of the country that Canada invites you to visit, it is worth noting that there is very little precipitation in winter, while humidity rises specifically during the warm season. This destination is ideal for those prepared for true northern weather but who prefer to enjoy nature during comfortable summer days.

The climate in Fort Simpson is distinguished by marked seasonality and a significant annual temperature range, typical of northern territories. Winter here is long and harsh: the coldest month is traditionally January, when the average temperature drops to -22.0°C, and night frosts often reach -25°C. Cold weather establishes itself in November and remains until March, requiring serious preparation and warm clothing from travellers.

Summer, conversely, brings pleasant warmth, compensating for the winter chill. The warmest and most comfortable month is considered to be July, with an average temperature of +19.2°C and daytime highs reaching +24.9°C. This time of year is characterised by mild weather without extreme heat, creating excellent conditions for outdoor activities and exploration. The warm period lasts from June to August, after which temperatures begin to drop rapidly.

Travellers should also take into account noticeable daily temperature fluctuations, especially during the transitional seasons and summer. For instance, in May and September, the difference between daytime warmth and evening coolness can exceed 10 degrees. Even in the height of July, after a warm day, night temperatures drop to an average of +13.5°C, so having a light jacket or sweater is advisable even during the warmest months.

The climate in Fort Simpson is characterised by a clear division of seasons, which directly influences the nature of precipitation. Since Canada in these latitudes is known for harsh winters, from November to March precipitation falls primarily as snow. Snowfalls here are a regular occurrence: during the winter months, an average of 6 to 7 days with precipitation is recorded, although the total volume remains small.

The most humid period falls during the summer season. The rainiest month of the year is considered to be June, when precipitation can occur over 12 days. July and August are also distinguished by higher humidity compared to winter—about 10 rainy days per month. Summer rains are usually not prolonged, but tourists are recommended to carry an umbrella or a raincoat.

The driest time of the year can be described as the end of winter and the beginning of spring. From February to April, the number of days with precipitation is minimal, amounting to only about 5 days per month. During this period, the likelihood of encountering snowfall or rain is significantly lower than in the height of summer.

When preparing for a journey to Fort Simpson, it is important to consider the harsh northern climate of this region. Winters here are long and very cold, so if your trip is planned for the period from November to March, the foundation of your wardrobe should be high-quality thermal base layers, a windproof down jacket, and insulated trousers. Be sure to arrange for warm footwear with non-slip soles, and do not forget a hat, scarf, and reliable mittens to feel comfortable at temperatures below -20°C.

Summer in these parts is quite pleasant and warm, but the weather can be changeable, so it is best to use the principle of layering. For a trip in June, July, or August, take T-shirts, a fleece jacket, and a light windbreaker that can be quickly removed or put on. Given that the number of rainy days increases in summer, it is worth packing a compact umbrella or raincoat, as well as comfortable waterproof shoes for long walks.

Regardless of the season, in Canada you will find sunglasses useful: in summer they will protect you from the bright sun, and in winter from the blinding glare of the snow. In the warm season, especially in early summer, tourists are strongly advised to carry insect repellent, as midges and mosquitoes can be quite active. Also, do not forget moisturising cream and lip balm to protect your skin from the wind and dry air.
