Snow seldom remains on the ground for more than a few days, as it is melted or sublimated by the warm chinook winds. Great Falls is a very windy city during the fall, continuing on into the spring season. The winds blow from the southwest during this period, and speeds from 25 to 50 miles per hour are not uncommon. Some people look forward to these Chinook winds knowing that the cold temperatures and snow will soon disappear. Summers and falls are quite pleasant, characterized by warm, sunny days and relatively cool nights.
Winds are light and humidity low.
Summer temperatures only exceed 100 degrees about every other year and rarely persist more than a few days. Typically, gardens do well, with vegetables easy to grow. The growing season is about 140 days. Churches of all faiths are represented in Great Falls. There are two accredited hospitals located in Great Falls, a number of highly rated clinics, and a medical research center.
