Be Prepared

Great Sand Dunes is a high elevation park in the Rocky Mountains, ranging from 7515 ft (2308m) to 13,604 ft (4146m). Storms can arise quickly, bringing cold, wet conditions any time of year. Be prepared for a wide variety of conditions during your visit.

Check the weather page for the best online forecast and detailed information, and view the park webcam for current conditions.

Summer high temperatures average 80 F, with lows in the 40s F. However, sand surface temperatures often reach 150 F in the afternoon before thunderstorms develop. In summer, plan your dunes time for early morning or evening to avoid burned feet, heat exhaustion, or lightning strikes. Summer afternoons are a great time to hike or 4WD into mountain areas of the park, as well as splash in nearby Zapata Falls.

Fall conditions are usually excellent, with sunny, calm days in the 60s-70s F and chilly nights.

Winter days are generally sunny and cold with highs in the teens - 20s F. The sand may feel warm in the intense alpine sun, but be prepared for blizzards anytime and subzero temperatures at night.

Spring can mean anything from blizzards to warm swimsuit weather - sometimes in one day! March and April are the two swowiest months in Colorado, but there are also warm days. Spring is the windy season throughout the western United States, and Great Sand Dunes may also be windy during a spring visit. Afternoons are usually the windiest part of the day; plan to hike on the dunes in morning. Late spring usually brings pleasant temperatures along with the peak flow of Medano Creek in late May.
