Weather is a central concern to those planning to visit Cape Krusenstern National Monument at any time of year. Summer temperatures on the coast are usually in the mid 50°'s F, with mid 60’s to 70° F for highs. Some days in July may reach 80° F. Average January lows are 5°F with possible lows of -50°F. Annual averages are not always good guidelines, however. In summer, visitors can experience snow, near freezing temperatures, and long periods of clouds, wind, and rain. For backcountry hiking and camping, wear plenty of warm clothing, dress in layers, and use rain gear. Wear sturdy hiking boots and waders for wet terrain.

Winds average 8 to 12 mph, but 50 to 70 mph winds may accompany storms and produce extremely low and dangerous wind chill factors. Any time of year, exposure and hypothermia are real threats to visitors and monument personnel. Be prepared – visitors should plan on meeting all of their own survival needs while traveling in the monument.

Summer days are long and energized with sunlight. The sun does not set between June 3rd and July 9th. Winter days are short. Although beautiful twilight lingers for hours each day, the sun is above the horizon only one 1 ½ hours on December 21st. The aurora borealis, or northern lights, are active year round, but best seen during high solar activity on the darkest nights of winter.
