Denver enjoys a semi-arid climate with 300 days of sunshine a year, but weather changes fast. The live forecast above shows today’s conditions; expect warm summers, chilly winters, and sudden afternoon thunderstorms from May to August.
What is the best time to visit Denver?
Late spring (May–June) and early autumn (September–October) offer the most comfortable weather for exploring. Summer highs reach 30–35°C, but afternoon storms are common. Winter brings snow and cold snaps, though the sun often melts it quickly. Pack layers year-round—a light jacket for evenings, even in July.
What should I pack for Denver?
For summer: shorts, T-shirts, a rain jacket, and sturdy walking shoes. Winter demands a warm coat, gloves, hat, and waterproof boots. Sunscreen and sunglasses are essential any month due to the strong UV at altitude. The city is good value outside peak ski season (December–February) and US school holidays.
Does Denver get snow in summer?
No, but snow can fall as late as May and as early as September. Summer precipitation comes as brief, heavy thunderstorms, not snow. Check the 10-day forecast before packing.
Is Denver weather dry or humid?
Denver is dry—humidity averages around 30–40%. This makes heat feel less oppressive and cold less biting, but you’ll need to drink plenty of water and moisturise. The UK weather hub has more on dry climates.
How accurate is the Denver 14-day forecast?
Long-range forecasts for Denver are less reliable due to its variable mountain weather. The 14-day outlook gives a trend, but check the weather in Denver 10 days or hourly updates for trip planning.
