Spring
(April and May)
Spring comes to the montane environs--elevations
8,000' to 9,500' (2,438 - 2,895 m)--in late April,
although snowfall is not uncommon at this time of
year. Unpredictable weather alternates between
warm and cold, wet and dry.
In June, spring is just reaching the subalpine
country -- 9,500' to 11,500' (2,895 - 3,505 m),
while summer is on the plains. Wildflowers begin
blooming at lower elevations in late April or
early May. Many trails are still snow-covered. In
late May, Trail Ridge Road opens for the season.
Fall
(September, October, 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. Elk mating season begins
in September and continues through most of
October. Trail Ridge Road usually closes for
the winter by mid-October. |
Summer
(June, July, August)
On the alpine tundra -- 11,500' to 13,000' (3,505
- 3,962 m) wildflowers bloom from late June to
early August. Afternoon thunderstorms and
wind are normal patterns. Always be prepared for
temperature drops of 10-20 degrees Farenheit.
Winter
(December, January, February, 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 clear cold
days during these months.
Most high country overnight trips require gear
suitable for -35 degrees or below.
Skiing and snowshoeing conditions are best in
January, February, and March. |
