April is a month of transition for Denver, as most any type of weather can occur and has: everything from snow to thunderstorms to sunny days.
Normal high temperatures range from the upper 50s to the mid-60s for Denver, with overnight lows warming from the low 30s to the upper 30s through the month.
On April 30, 1992, a high of 90 degrees set a record for Denver’s warmest April temperature.
Through April, Denver will see a variety of air masses. Arctic air will occasionally move in with eastward-moving Pacific storms, often bringing snow. Warm, moist air from the Gulf of Mexico will move north and bring thunderstorms, sometimes just before the snow falls. Warm, dry air from the Southwest can bring warm days with low humidity.
April is Denver’s third-snowiest month of the year, with an average of 9.1 inches of snow, and the windiest month, with an average 10-mph wind speed. On average, two thunderstorms will develop during the month. There also is the potential for severe weather, with hail, high winds and tornadoes.
