Boise, Idaho, experiences a semi-arid continental climate with four distinct seasons.
Spring (March – May): Weather during this season can be unpredictable, ranging from warm and sunny to rainy and cool. It’s generally a good time to visit, especially for those interested in seeing blooming flowers at the Idaho Botanical Garden.
Summer (June – August): Summers in Boise can be hot, with temperatures often reaching into the 90s (°F). However, the low humidity keeps the heat tolerable, and evenings tend to cool down nicely. This is a great time to enjoy outdoor activities like hiking, biking, and river rafting.
Fall (September – November): Fall is considered one of the best times to visit Boise. The weather is mild, and the fall foliage is stunning, particularly along the Boise River Greenbelt.
Winter (December – February): Winters can be quite cold, with temperatures often below freezing. Snowfall is common, which makes this season ideal for winter sports enthusiasts who enjoy skiing or snowboarding at nearby Bogus Basin.
In terms of events and festivals, the city hosts several throughout the year that might be of interest. The Treefort Music Fest in March is a major draw, as is the Idaho Shakespeare Festival which runs from May to September. The Hyde Park Street Fair in September offers music, food, and arts and crafts in the historic Hyde Park district.
The “best” time to visit really depends on your interests and the activities you’re planning on doing. Summers and early fall are generally the most popular times to visit, but each season has its own charm. Always check the current weather forecast before your trip and pack accordingly.
