The Four Winds

SADIE 80s
Strong southeast winds move over the Kenai Mountains, funneling down glaciers and passes. These warm, wet maritime winds from Prince William Sound and the Gulf of Alaska can blast through Sadie and Tutka Bay Coves at 80 miles per hour.

FISH WINDS
Northwest winds from Siberia intensify winter's cold. In summer, the same winds warm up and blow Cook Inlet salmon into Kachemak Bay. The Alaska Range intercepts much of the arctic weather before it hits home.

DAY BREEZE
Southwest winds funnel through Cook Inlet from the Gulf of Alaska. A galloping sea of white-crested waves rolls the length of the Bay and pounds the shores. Small boats race for safe harbor. In summer, as the land heats, rising air draws in wind from Cook Inlet. This gives rise to the water-churning day breeze, especially on sunny afternoons.

WINTER WINDS
Cold winter winds from Alaska's interior blow across the head of Kachemak Bay. The marriage of northeast winds and quicker-freezing estuarine headwaters send ice downbay to ram the Homer Spit and clog the harbor.
