Weather in Great Sand Dunes

Great Sand Dunes National Park’s weather varies significantly depending on location. The great majority of visitors come for the dune fields. Here temperatures are cold in late fall, winter, and early spring, with generally low precipitation. Summer temperatures are usually pleasant, but temperatures on the sand can be much, much higher than the air temperature (as high as 140°F or more).
