Sunny mornings, possible afternoon thunderstorms, and cool nights. Weather conditions change quickly in mountainous areas and snow is possible year-round. Dress appropriately for each season—comfortable clothing, layers, rain gear, and wear plenty of sunscreen.

Unpredictability is the key word for mountain weather in the Rockies. As a result, the Colorado mountaineer cannot be indifferent about the weather and must be prepared for extreme conditions.

The Continental Divide, jutting into the prevailing west winds, is often capped by turbulent and wet storm clouds. The Bear Lake-Glacier Gorge region is often afflicted by poor weather, even when skies are clear a few miles to the east. Statewide weather trends announced in forecasts are nevertheless a valuable general guide to park weather, particularly for skiers planning extended tours.

Usual day temperatures vary from the low teens to the mid or high 20s. Night temperatures extend from the teens to well below zero. Cold fronts may lower temperatures to -30 degrees F, and the wind chill on exposed flesh can easily lower the effective temperature to -80 degrees F. Day tourers to open areas and all overnight tourers must be equipped to handle these polar conditions.

High winds, sometimes exceeding 100 miles per hour, are perhaps the greatest single weather danger in the park. Above treeline, skiers may be blown off their feet, experience zero visibility, and have a total loss of orientation. Skiers enveloped in a "white-out" may be moving downhill and think they are standing still, or standing still and think they are moving. Skiers should stick close together and immediately retreat below treeline, cautiously probing for cornices, drop-offs, and other unstable areas.

North-facing slopes offer the most snow, but also the most avalanche danger. South-facing slopes grow sticky in the sun and crusty in the shade, a condition that can snap ski tips unexpectedly. Traverses between drainages are difficult because most valleys have steep glacier-cut walls. Rock outcrops sometimes require detours, even along valley floors.
