Idaho Weather And Climate

Idaho weather is milder than some people may assume about a Northern state that isn't located on an Ocean and is at a slightly higher elevation. The Pacific Ocean still has a moderating effect on Idaho, providing cloud cover and humidity in the winter. Don't be fooled, however, winter can be cold, and summer can be somewhat hot, although usually dry.
