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. This raises air temperatures dramatically, which can last for several days.
That's when air flows over the mountains to the west and sinks on the leeward (eastern) slopes of the foothills and warms up. Winter is also when the Denver area gets pounded by a phenomenon known as the 'Chinook'. About once a year, a snowfall of over a few feet occurs. Heavy snowfalls can occur between October and March, often alternating with days of high temperatures and sunshine.
Denver residents enjoy a mild climate and the third most sunshine of any US state, with four pronounced seasons.
