About Lightning in Colorado

Located at approximately 40°N latitude, Colorado is home to the Rocky Mountains, where afternoon solar heating of mountain slopes triggers rapid upslope thunderstorms that roll onto the Front Range and eastern plains. Thunderstorm frequency varies within state boundaries, so this page does not publish an unsupported statewide annual average or national rank.

In Colorado, afternoon solar heating of mountain slopes drives rapid orographic thunderstorm development. Peak thunderstorm activity occurs during May through August, when conditions align for the most frequent lightning strikes. With a population of 5.8 million residents, storm awareness and lightning safety are important considerations for anyone living in or visiting Colorado.
