Montana experiences a diverse climate with significant seasonal variations due to its large size and varied geography. The state generally has cold, snowy winters and warm, dry summers. Weather can differ greatly between regions, especially between the mountainous western part and the plains to the east.

Summers tend to be warm and dry, with daytime temperatures ranging from the mid-70s to mid-80s Fahrenheit (24–30°C), but nights can be cool. Spring and fall are transitional seasons with variable weather, including occasional rain and fluctuating temperatures.
