Because Alaska is so big, the climate here can vary from one part of the state to another. Seasonal changes also contribute to varying weather conditions throughout Alaska. Below please find some average temperatures by month for various regions of the state to help provide an idea of what to expect based on when visiting.

Due to Alaska's limited road system and remote nature, many of Alaska's attractions are accessible only by plane. Flying within Alaska is a great experience; however poor weather conditions may delay or even cancel flights. For these reasons, weather is a crucial part of planning travel in Alaska and Yukon. It is especially important when travel plans include flights in small planes to plan for 'weather window' days. These 'extra' days will reduce any significant effect poor weather may have on the private program and typically require a simple pre or post night, particularly when traveling along Alaska's coastal regions.

In general, tour excursions will take place regardless of rain or shine and travelers should be prepared. Only in the event an excursion is cancelled by the supplier due to weather conditions for safety concerns will clients generally receive a refund.

No matter where you are or what you are doing, it is important to plan for a variety of conditions. We highly suggest dressing in layers and packing a pair of gloves/mittens and a hat, regardless of when/where you are traveling in Alaska. Conditions can change quickly and it's best to pack an extra layer or two, especially when your travel plans include any kind of water-based activity.
