One of the characteristic features of the weather in Kalispell is the relatively low total amount of precipitation throughout the year, usually not exceeding 2-3 mm per month. However, the number of days with precipitation varies noticeably: in winter and during the transitional seasons (for example, in April, May, November, and December, there are about 15-16 days with precipitation), they are more frequent, which in winter likely means snowfall. The summer months, especially July and August, stand out with the fewest days with precipitation (5-6 days), making them the driest and sunniest periods for visiting.

A characteristic feature of the summer is significant diurnal temperature fluctuations: nights can be noticeably cooler, with temperatures dropping to 12-13°C. This difference between the daily maximum and nightly minimum, reaching over 15°C in July, often indicates low air humidity. June serves as a transitional month to summer warmth, with an average temperature of 14.8°C and maximum values reaching 21.1°C.

Monthly average temperatures during this period range from -2.6°C in December to -5.7°C in February.

A specific precipitation pattern is observed in the city of Kalispell. The total annual amount of precipitation is low, but it is distributed throughout the year with noticeable seasonal differences in frequency. The largest volume of precipitation, albeit modest (on average 3 mm per month), falls in May. The driest months are July, August, and September, when the monthly norm of precipitation is only about 1 mm.

The summer months, especially July and August, can be described as the dry season, as the lowest number of days with precipitation is recorded during this time – only 5-6 days per month. Conversely, spring (April, May) and the period from November to December are distinguished by the highest frequency of precipitation, when the number of "wet" days reaches 16 per month. Despite the frequency, the intensity of precipitation during these periods remains low.

The nature of precipitation changes depending on the season. In winter (December, January, February) and in November, with negative average temperatures, precipitation falls primarily in the form of snow. In transitional months, such as March and October, both rain and snowfall are possible. In the warm season, from April to September, rain falls. Considering that even in the "wettest" months by frequency the total amount of precipitation does not exceed 2-3 mm, we are mainly talking about light and short-lived precipitation, such as drizzle or light snow, rather than heavy downpours or abundant snowfalls.

When planning a trip to Kalispell, it is important to consider the significant temperature fluctuations throughout the year.
