Climate

Summer temperatures in this part of Alaska average in the high 40s to low 50s degrees Fahrenheit, with most days overcast and wet. Winds are frequent and even in summer these conditions can lead to hypothermia, the dangerous lowering of the body's core temperature. As symptoms progress it becomes increasingly difficult to respond to them. Be aware of this danger and know how to avoid and treat hypothermia. Wearing layers of clothing makes it easier to regulate your body temperature.
