The weather when lodging and recreating here in Jackson Hole, Wyoming and Grand Teton National Park can change rapidly. Every season has its advantages. Here are some typical weather patterns throughout the year.
Spring (late April - June):
Mild days and cold nights intersperse with rain and occasional snow. Valley lakes usually thaw by late May. Depending on the snow pack, snow level remains just above valley elevation until mid-June. Valley wildflowers begin blooming as the snow melts, peaking in June and July.
Summer (July and August):
Warm days and cool nights prevail, with afternoon thundershowers common. Snow level gradually retreats, with divides between mountain canyons free of snow by August. As valley flowers fade, canyon and alpine wildflowers peak.
Fall (September - November):
Sunny days and cold nights alternate with rain and occasional snow. Aspen and cottonwoods turn gold in late September and early October. As snow becomes persistent by late fall, elk move to wintering areas at lower elevations.
Winter (December-April) The Ranch is closed in the winter due to heavy snowfall and limited transportation.
