How many inches rainfall does Alaska get in a year?

Answer 1

Alaska's climate varies immensely, from the cool and super-humid southeast to the brutally cold and dry Arctic Coast.

Total precipitation over Alaska is typically around 3,000 millimetres (120 inches) in the southeast, around 300 to 400 millimetres (12 to 16 inches) in the Interior and West, and around 100 millimetres (4 inches) on the North Slope.

In the high southeastern mountains, as much as 150 metres (5,905 inches) of snow may fall per year, which is equivalent to 11,000 millimetres of rain (though on Mount Logan it never gets warmer than -20˚C or -4˚F and is mostly around -40˚C or -40˚F).

Actual rainfall (liquid precipitation) over Alaska varies from around 40 millimetres (1.5 inches) over the North Slope, to between 200 and 300 millimetres (8 to 12 inches) over the interior and West. In the warmer southern coast rainfall varies from around 12 inches over the rain shadow areas near Anchorage to around 3,000 millimetres at Yakutat and 3,800 millimetres at Ketchikan where it can be too mild for snow even in winter.

Answer 2

Alaska is a huge state with large variations in terrain, so snowfall varies a lot. Snowfall is least in extreme SE Alaska and also on the North Slope where it is too cold for much snow to fall. Snowfall here averages about 25-30 inches annually.

Anchorage gets 70.6 inches of snowfall in an average year, and Juneau averages nearly 100 inches. But some of the highest totals occur along the south coast where precipitation is nearly constant in the winter.

e.g. Valdez:

Average annual snowfall = 325.6 inches

Record snowfall = 560.7 inches (1989/90)

Thompson Pass (not far north of Valdez) holds the record for the state of Alaska.

Record snowfall in Thompson Pass = 974.5 inches

Thompson Pass' record in 1 month is 297.9 inches February 1953

Answer 3

Rainfall would vary quite a lot across the whole of Alaska (it's a big place). Anchorage gets around 330mm annually. Most meteorological bureaux measure rainfall in millimetres, the Imperial system is ancient and unwieldy.

Answer 4

There is technically not a 'Rainy Season' for Alaska, as Alaska's Summer's are only slightly rainier than the rest of the US. May is relatively dry, with only a 25% chance of rain, but as the Summer progresses, the likelihood of rain increases, as in Autumn, the average chance of rain on any given day is 50%, and it only worsens as the year progresses.

Answer 5

Alaska gets roughly 152 inches of rain in a year.

Answer 6

Alaska receives an average annual rainfall of around 22 inches. However, this can vary greatly depending on the specific region within the state.

Answer 7

An average of 15.29

Answer 8

16-0 Inches Im smart
