The climate of Southcentral Alaska -- the region encompassing Anchorage, Seward, Homer, Prince William Sound and Wrangell-St. Elias -- is mild, at least by Alaska standards. The temperatures are moderated by the Gulf of Alaska, and the truly cold winds of the north are often blocked by the Alaska and Talkeetna mountain ranges.

Southcentral Alaska doesn't get as much rain as Southeast Alaska, but it gets a lot more snow. On the other hand, it has a lot more clear days.

When moisture-laden air blowing off the Gulf of Alaska meets the chilly Alaska, Chugach, Talkeetna, Wrangell and St. Elias ranges, precipitation happens. In July, August and September, especially along the Gulf coast, rain falls. In the winter, there's lots of snow. This is often most apparent along Prince William Sound. Valdez, for example, averages 303 inches -- 25 feet -- a year, and Whittier gets 250 inches.

Although so much snow requires shoveling and plowing in town, it's beloved by skiers and snowmachiners. Snow in the mountains feeds the glaciers and the myriad streams that salmon come home to. Snow and rain also nurture the lush coastal forests.

Blocked from the Gulf by mountains, Anchorage's official measuring station at the international airport gets only 70 inches.

The snow near sea level generally melts away by early May. When termination dust -- the first coating of mountaintop snow -- falls in late August or early September, Alaskans know winter isn't far away.

Summer sunlight in Anchorage lasts 19.5 hours at the June solstice. At the winter solstice, daylight lasts 5.5 hours.

Here are monthly averages -- high temperature, low temperature, precipitation (inches of rain and melted snow), snowfall and snow depth for Southcentral locations: Alyeska (Girdwood), Anchorage, Chitina, Cordova, Elmendorf Air Force Base, Glen Alps (Anchorage), Glennallen, Homer, Hope, Kenai, McCarthy, Moose Pass, Nabesna, Nikiski, Palmer, Seward, Skwentna, Talkeetna, Thompson Pass, Valdez, Wasilla and Whittier.
