Alaska Climate

Whenever and wherever you travel in "The Great Land," clothing is always a primary consideration. Emphasis should be based on comfort because the dress code is informal and casual. A layered technique is extremely good here.

Temperatures in Alaska during the summer range from 60°F-80°F. Nighttime and early mornings are cooler, from the 40's - 50's. Late August and September departures could encounter cooler temperatures and slightly fewer hours of sunlight, as fall arrives early at these latitudes.
