About Lake Clark Weather
Lake Clark National Park's weather is broken into two areas: those areas along the coast and those in the interior of the park. The sea moderates the temperatures, and leads to a higher level of precipitation. The interior is very cold in winter, and has much less precipitation. The weather in Lake Clark is even more unpredictable than most areas of Alaska. High winds, rain, snow, fog, and sunny skies can occur at any time, often during the same day. The statistics below are taken from Port Alsworth, located within the park and the location of park headquarters.
Visitation Seasons

Spring is still mostly a time of quiet. Only in the last few weeks of the season, in June, does visitation really start. Most park and concessioner services start up early June.

Summer is the time virtually all visitation to Alaska occurs, and Lake Clark is no exception. The entire season sees heavy visitation, with the month of July being by far the busiest. Activities trail off as the season closes, with a second bear season on the Brooks River happening in September.

By the time autumn arrives, the visitation season is pretty much over in Lake Clark. Winter starts to reclaim the landscape, albeit a bit slower than in many other parts of Alaska. Most activities have ended and facilities have closed.

Winter is a time of extreme quiet in Alaska's parks, including Lake Clark. It may be difficult to even get to the park area, let alone do anything. Winter is not the time to come to Lake Clark.
