August on the ground

Weather & conditions

Mild and increasingly showery; the first crisp nights arrive. High 67°F, Low 50°F.

August trades a little sunshine for big rewards — berry season, salmon-filled streams around Ketchikan and the Kenai, and the aurora season's return in the last week as nights darken.

What to do in August

Bear and salmon viewing on Tongass forest streams
Blueberry picking on open tundra
First aurora watches of the new season

Best-fit rigs: Motorhome · Truck or van

Know before you go

Rain gear matters more each week, and bears are focused on the same streams you are — keep food sealed and distance generous.

Bears are active; carry bear spray and know food storage rules. Mosquitoes are thick in early summer.
