Spring and Fall are mild and the favorite times of year to go exploring much of Idaho, especially if mountain biking, camping, and fishing are at the tops of your recreational interests.
The four seasons in Idaho are broken down like this:
Spring – typically from the end of February to mid-June, with an average high of 63° and low of 36°, spring gives way to warmer afternoons with cool early mornings and evenings.
Summer – a favorite season in Idaho, the sunny days of summer run from mid-June to mid-September. The average high is 85°, although it is not uncommon to see mid 90’s on occasion. Low’s are in the low 60’s making this the perfect season be outside.
Fall – there is no denying the vibrant beauty of the Treasure Valley in fall from mid-September through mid-November. With average daytime highs in mid 60’s, this is the time when mountain bikers and hikers like to take advantage of the cooler temperatures in the local foothills.
Winter – with an average high of 47° and average low of 27°, winters in Idaho are fairly mild. It is common to see a few inches of snow in the valley during the winter. Bogus Basin ski resort is just a short 21 miles up the mountain making winter a favorite time of year for ski and snowboard enthusiasts.
There is no better place to experience the four seasons in Idaho than in the Boise, Treasure Valley area.
