Alaska Weather & Daylight

When planning their vacations, most travelers have questions about the weather in Alaska. What will the weather be like? How much daylight will there be? What clothes should we pack? Alaska is a big state and weather can vary greatly by region and season. The table below shows average temperatures and hours of daylight across the state.

Alaska does not have a 'rainy season'. Southeast Alaska typically receives the most rainfall, while warmer sunny weather is typical of interior Alaska summers. When packing for Alaska travel, your best bet is to dress in layers regardless of which regions you plan to visit. Weather changes quickly in Alaska, so be prepared. Alaska is also very casual. Bring along jeans, slacks, sweaters, sweatshirts, t-shirts (short and long sleeve), a rain jacket and comfortable walking shoes. See our Alaska packing list page for suggestions.
