Much like November, colder than normal temperatures were the norm for Alaska, with all twenty first-order stations reporting temperatures below the expected values.
Repeated early autumn storms pounded Southcentral Alaska in September, bringing high winds and rain to the region that resulted in wind damage and flooding.
The mean average annual temperature in 2012 for the 20 stations was 30.0°F, a substantial negative departure of 2.9°F from the 30-year normal of 32.9°F.
