Temperatures over the decades in September have varied from as high as 71 in 1979 to as low as nine above in 1992.
Now, September is the last month of the western Alaska rainy season. Average total precipitation just over two inches at Nome. In past years, September totals have ranged from seven and a half inches in 1986 to just six one hundredths of an inch in 2008 while the first snow flurries of the season typically occur in September.
Accumulating snow at Nome airport happens only about one year in three. September's note is, of course, much more common at higher elevations of the Seward Peninsula.
