People often speak of the Climate of Alaska and give it as the reason for Alaskans being the worst dressed of the Nation. This post presents you the actually different climate regions of Alaska, and their weather conditions with respect to precipitation and temperature. It explains why arguing with Alaska as a place and/or Alaska’s cold climate is plain wrong. After reading you can see why Alaska is no reason to dress without trying at all.

Alaskans’ Clothing Style in the Public Prejudice
In 2012, Travel & Leisure published a poll that named Anchorage the worsted-dressed city in America. Many people explained the ranking by “it being Alaska,” i.e. the last Frontier and/or “Alaska’s cold climate.”
Alaska Has More than One Climate
Second, there is no such thing as Alaska’s cold climate. Alaska when projected onto the Lower 48s reaches from coast to coast. For my European readers, Alaska is larger than Europe from the Ural to Portugal. Given the size, it is obvious that Alaska has a variety of climate regions. They are called climate divisions by the National Weather Service. These climate divisions refer to areas of similar landscape, topography, vegetation, and similar meteorological conditions (temperature, humidity, wind, precipitation).
Alaska Has Three Main Climates
The Köppen-Geiger classification distinguishes three main climates in Alaska, namely warm temperate (C), snow (D), and polar climate (E). These climate regions are subdivided with respect to summer and winter temperature ranges and further subdivided with respect to when precipitation occur, i.e., year round (f), dry summer (s), or dry winter (w). In Alaska, these climate sub-classifications have shifted since onset of recording, and the borders are fluent.
Polar Climate on the North Slope
The North Slope has cold, dry polar tundra climate (ET). Summers are cool. In July, the warmest month, mean minimum and maximum temperatures at Barrow, for instance, are 35F (2oC) and 47F (8oC), respectively. The combination of cold air and strong wind makes winters dangerous on the North Slope. The annual total precipitation is about 4.49 inches (114 mm). Snow can occur year round. Precipitation peaks in August with July and September having the second and third most precipitation.
The Snow Climate of Alaska in the Interior and Anchorage
The climate of the Interior (Dfc) is subarctic (D) with long, very cold winters, and (too) short, cool summers (c), in which the most of the precipitation occurs. Precipitation occurs year round (f). Thus, the Interior and, hence, Fairbanks have similar climate as Norisk (Russia) or Mohe (China).
Anchorage’s winters are cold, but much warmer than those in the Interior. Anchorage has a climate with a strong, sub-polar maritime component similar to that in Murmansk (Russia). Due to the maritime influence, winters are relatively moderate in Anchorage because its climate borders sub-polar oceanic climate. Anchorage’s precipitation occurs year round with a distinct maximum in summer. Except for the precipitation aspect Anchorage’s climate is more similar to that of Reykjavik (Iceland) or Tórshavn (Faroe Islands) than to that of Fairbanks.
Climate of Alaska: Conditions on the Panhandle
Warm temperate also called maritime climate exists in Southeast Alaska along the Panhandle. Here the polar front leads to changeable weather with overcast sky and year round precipitation (f). Southeast Alaska’s summers are cool due to the cool ocean currents and winters are milder (b) than in regions of similar latitude due to the high heat capacity of the close ocean. This means that the climate in Ketchikan (Cfb), for instance, is similar to that in Bergen (Norway), London (UK), Zürich (Switzerland), Paris (France), Melbourne (Australia), Auckland (New Zealand), or Sky Valley (Georgia, USA). More on how to dress for maritime climate.
Why the Climate of Alaska Is No Explanation for Being Worst Dressed
First, climate is not weather. Instead, climate is the longterm mean over typically 30 years of the respective weather. It is the statics of a time series of temperatures, daily minimum temperatures, daily maximum temperatures, daily precipitation, etc.
Second, Anchorage is not Alaska. It just happens to be the city in Alaska where the majority of the Alaskans live. Juneau, the second most populated city, has the largest area. It winds along the fjord with steep glacier covered mountains to one side and water to the other. Fairbanks has the third most inhabitants and is located in the wide valley of the Tanana Flats with the White Mountains and Brookes Range to the North and the Alaska Range to the south.

What kind of climate do you have where you live? Hot summers and cold winters or warm summers and cool winters? Do you have precipitation year round or a distinct dry and wet season?
