Since storms often develop by early afternoon, plan hikes so you reach the highest point before noon and descend soon after. Always take rain gear!

Seasonal Patterns:
Winter (December January, February and March): Lower elevations on the east slope of Rocky Mountain National Park are usually free of deep snow. At higher elevations arctic conditions prevail. Sudden blizzards, high winds, and deep snowpack are common. The west side of the park experiences more snow, less wind, and sunny but cold days during these months. Most high country overnight trips require gear suitable for -35 degress F or below. Skiing and snowshoeing conditions are best in January , February and March
Spring (April and May): Spring comes to the montane environs in late April - elevations of 8,000' to 9,500'. In June, spring is just reaching the subalpine country - 9,500' to 11,500', while summer is on the plains. Wildflowers bloom at lower elevations from late April to early May. Many trails are still snow-covered. In late May, Trail Ridge Road opens for the season.
Summer (June, July, and August): On the alpine tundra - 11,500' to 13,000', wildflowers bloom from late June to early July. Afternoon thunderstorms are a normal pattern. Be prepared for temperature drops of 10-20 degrees.
Fall (September, October, and November): September and October bring clear, crisp air, blue skies, and generally dry weather. An early snowstorm may occur. Aspen leaves start changing colors in mid-September. The elk mating season begins in September and continues through most of October. Trail Ridge Road usually closes for the winter by mid-October.
