This is because this area is in the storm track of the Aleutian low pressure cells that pass by from west to east with great frequency. Certain bays, like Urilia Bay, become unfishable during times of strong westerly winds. Like this location? Comfort Levels: Given average maximum temperatures and humidity levels generally you should not anticipate any discomfort from heat (see heat index for more information). Throughout the month of December daytime temperatures will generally reach highs of around 2°C that's about 36°F. There is little concern about whether the day will be sunny or cloudy or even rainy, it is the wind that matters most because it determines the safety of traveling by boat or skiff. The islands experience a maritime climate. The regular temperature in Alaska is about 38 degrees Fahrenheit (3 degrees Celsius) but the weather will change during seasons or months. James Estes, now an emeritus professor at the University of California Santa Cruz, has been studying the Aleutian Islands since 1970. If the storm center passes to the north of Unimak, there is a veering wind shift from SE, to SW, to W, to NW as the storm moves by. Climate. Summer temperatures are also moderated by the strong marine environment so that daytime highs seldom surpass 70 degrees F.  Temperature extremes increase as one travels up the Alaska Peninsula, so that Cold Bay is slightly colder in winter and warmer in summer than Unimak Island. In recent years the maximum sustained wind speed has reached 96 km/h, that’s the equivalent of around 60 mph, or 52 knots. During such cold winters, the Bering Sea can be covered with ice as far as Isanotski Strait and cold Siberian air can drive the temperatures down to near zero. To maintain relevance to current weather trends the displayed information has been calculated using data collected over the past two decades. Easterly winds are relatively uncommon. Below is a picture of ice filling Isanotski Strait in False Pass.4, Amak Island lies just off shore from Isanotski Strait in the Bering Sea and it was historically a walrus hauled out, indicating that the edge of the Bering Sea ice pack was near by. The Aleutian Low is one of the principal causal factors of the weather and climate in the Unimak region. This feature also encompasses non-stationary systems of both low and high pressure (cyclones and anticyclones) that form and dissipate along fronts and rapidly move in a broad sub-polar band of west-to-east flowing air currents widely known as the prevailing westerlies. The Islands of the Four Mountains in Alaska’s central Aleutians are about as inhospitable an environment as a person can imagine. The maximum Ice Extent in the Bering Sea is shown in the maps to the right. Given the small landmass, the human footprint is quite large — the region is ranked 5th out of the 13 regions for human impacts. Its position and size can be shown to be correlated with major indices such as ENSO, and in this manner it conveniently represents a mechanism for assessing impacts from teleconnection patterns."1. American Geophysical Union annual … This means that the winds will change direction and intensity as a low pressure storm passes by. The Heat Index is a measure of how hot it feels when relative humidity is added to actual air temperature. The storm track almost always leads from the west toward the east along the Aleutian chain.

The chart below plots the average number of days in any month that you can expect to see snow falling. The average temperature difference between July and January is only about 10 degrees F. The moderating influence of the marine environment is the primary reason for this small temperature difference. Their website on "The Cryosphere Today" can be accessed here and it contains the most up-to-date information on ice in the Bering Sea, the Beaufort Sea and other world sea ice areas. They extend in an arc southwest, then northwest, for about 1,100 miles (1,800 km) from the tip of the Alaska Peninsula to Attu Island, Alaska. Calm winds (no direction) in Cold Bay are observed only 2% of the time. An active weather pattern will impact the U.S. this weekend into next week. The chart below plots the average monthly precipitation amount. The information presented below gives detailed historical monthly average weather conditions along with exceptional weather occurrences.

The Aleutian Island is mostly cone volcano’s and some are still activate, but only on one side of the Island not all of the volcano’s can still activate. The days with the heaviest rainfall occurs in the fall, but strong storms can bring southeast winds and heavy rainfall at other times of the year. The islands are devoid of native vegetation except for grass and stunted willows. Westerlies often occur in the fall, as shown in the wind direction rose for September. The stronger ALs generally move eastward south of the Aleutian Islands. Winds and tides can bring drift ice from the edge of the Bering Sea ice pack into Isanotski Strait and as far south as Ikatan Bay. Early North American inhabitants are thought to have crossed the land bridge over the Bering Sea from Europe thousands of years ago.
