Climate in Denver


Climate in Denver

Denver residents enjoy a mild climate and tons of sunshine, with four distinct seasons. The winter months of December through March can and do bring short spells of cold temperatures and heavy snow to the region. Denver receives a major blizzard only every 6 years on average, most bringing less than 8 inches of snow, while the foothills just west of Denver get a whole lot more. Winter is also when the Denver area gets pounded by a phenomenon known as the "chinook". That's when air flows over the mountains to the west and sinks on the leeward (eastern) slopes of the foothills and warms up. This raises air temperatures dramatically which last for several days. If you're planning to visit Denver during the winter, be prepared with full winter gear just in case, but also pack a light sweater and t-shirt; the weather is usually very sunny and mild.
Evening thunderstorms are common in late spring and fall

Spring in Denver is pleasant, though generally rather brief. Trees begin budding by late March and are in full leaf by mid April to mid May. March, on average, is Denver's snowiest month. By June, Denver enters its summer season. Temperatures typically rise in earnest at this time, with most heat waves beginning in mid June and continuing through July, usually Denver's hottest month with temperatures in the high 80's to mid 90's. By late-July, the southwest monsoon kicks in. In August short spells of thunderstorms occur about three to four days per week. By late August temperatures begin to drop with a noticeable difference between day time and night time temperatures. As the days get shorter through September and October day time temperatures drop to the high 50's to mid 60's. Slather on that sunscreen all summer long; the rays are strong and the air is dry, with temperatures often reaching the upper 90s in July and August. Autumn is a peaceful time to visit, with mild temperatures, little severe weather and lots of that famous clear blue sky. You'll get to see the trees display their fall colors, which usually peak around mid-September in the mountains and October in the city itself. October usually brings the first snowfall of the season to Denver, although it's very light. By November, it's clear that winter is on its way, with plenty of clouds, some snow and much cooler temperatures.
