On average, wet and cool conditions predominate in spring, summer, and fall. Summer temperatures range from 30˚ to 80˚ Fahrenheit (-1˚ to 27˚ Celsius). Winters are drier and colder. Winter temperatures are even more variable than summer and can range anywhere from -35˚F to 50˚F (-37˚ to 10˚ C). Most ponds and lakes are frozen by mid to late fall and snow covers the higher elevations of the park until late May and early June. The Pacific coast of Katmai experiences cooler, wetter, and stormier conditions than the interior of the park. Strong winds are common all year.
Follow these tips to brave Katmai's tempestuous weather:
- Bring high quality waterproof clothing: A reliably waterproof outer layer can keep you dry and make what would otherwise be a cold and miserable day into an enjoyable one.
- Dress in layers: Start with a base layer to manage moisture. Lightweight, wicking, and quick drying clothing works well for this. Wear an insulating layer such as a fleece jacket next to trap warm air next to your body. Lastly, add a waterproof shell such as a rain jacket to shield you from the elements.
- Keep your head and hands covered: Even during the relatively mild temperatures of summer, a warm hat and lightweight gloves can add significantly to your comfort level.
