Contrary to what people who live outside of the state of Colorado believe, the winters in eastern Colorado are not severe. In fact, in the area east of the Continental Divide, winters can be very mild with only a few snowfalls per year. The truth is, any day of the year can be a great day to visit Boulder, Colorado. It’s impossible to say whether any day in the middle of winter will be 60 degrees Fahrenheit, or below zero.

The general climate in the entire state of Colorado is dry. Colorado is not a humid state by any stretch of the imagination. The average humidity percentage is very low all year long. Winters in Boulder usually consist of a few snowy days interspersed with very mild and sunny days.

Springtime in Boulder, as well as Denver, can be sporadic. Blizzards can occur as late as March or April, but those same months can also be rainy and even warm.

During the summer, the weather in Boulder remains dry, but it can get very hot, with stretches of seemingly unending 90+ degree Fahrenheit days. However, hot days are often cooled by afternoon thundershowers. The evening hours in the summer are often pleasant and can even be cool.

The fall in the Boulder and Denver areas is almost non-existent. It always seems to go from hot weather in the summer to wintry days with snow and cold weather – completely bypassing fall altogether.

Nonetheless, there are always 300 or more sunny days in Boulder, so visiting at any time of the year will most likely be enjoyable in terms of weather.
