September weather forecast and climate
Colorado, USA

September is one of the best times to visit Colorado, dressed in the colorful cloak of autumn. The temperatures are moderate, and the weather is pleasant in the absence of a blazing sun. The usually brown landscape adorns beautiful colors, and the scenery looks heavenly in the backdrop of the white snow-capped peaks.
The average high temperatures in early fall are in the warm 70°F (21.1°C) to 80°F (26.7°C) range, and the average low temperatures are in the mild 40°F (4.4°C) to 50°F (10°C) range.
Rain rarely hits peak numbers in Colorado, and September hardly receives to the tune of 1" (25mm) to 2" (51mm) in the majority of the state.
Mountain trails are open, and the state and national parks dazzle with the changing shades of the wild flora. Autumn is a wonderful time to visit Colorado as the weather is pleasant, and the days have comfortable temperatures, while the clear nights are ideal for campfires and stargazing.
