WEATHER INFO

Temperatures are relatively cool all year at the park elevation 8000 ft. Conditions are most often calm, but winds can arise, especially in spring and during storm fronts. Daytime temperatures feel warmer here year round due to intense high-altitude sunlight, and mid-day summer sand surface temps can be 160 degrees F! Plan to explore the dunes morning or evening during summer. Nights are cool in summer, and frigid in winter. Visit https://nps.gov/grsa/planyourvisit/weather.htm for details
