Alaska Weather & Climate Find out for yourself by reviewing the table below, comparing Alaska's weather to your hometown, or using our daylight calculator. Summer daytime temperatures range from 55° - 70° F, but you'll feel warmer due to long hours of direct sunlight. Still, know what to wear in Alaska and dress in layers. Also know that the weather gets rainier as summer progresses.

What are some examples of constructive and destructive forces that change earth's surface? Coastal erosion has become a major issue in recent years in the Arctic, with Alaska’s North Slope losing as much as 30 meters (100 feet) per year! Climate change is thought to be the underlying cause. As the climate warms and sea ice melts, more of the sun’s energy is absorbed by ocean water.

Climate of Alaska Average monthly precipitation is generally highest in the autumn months, especially October, and lowest in May or June. This is also the only region in Alaska in which the average daytime high temperature is above freezing during the winter months.There are even a few regions in the far southeast Alaska where the average temperature is warm enough to grow some cold-hardy palm trees.uneau averages over 50 inches (1,270 mm) of precipitation a year, while some other areas in southeast Alaska receive as much as 275 inches (6,980 mm). Average monthly precipitation generally peaks in September or October, and is lowest in May and June.

The chilling science on Alaskaâs melting permafrost The chilling science on Alaska’s melting permafrost. Up to a quarter of the permafrost that lies just under the ground surface in Alaska could thaw by the end of the century, releasing long-trapped carbon that could make its way into the atmosphere and exacerbate global warming, a new study finds. 1  Polygonal lakes created by melting permafrost on Alaska’s North Slope.NASA.

National Climate Report - March 2017 The Alaska statewide average temperature was 4.1°F, 6.7°F below average. This was the 12th coldest March in the 93-year record for the state and coldest since 2007. This ended Alaska's stretch of 17 consecutive months, beginning in October 2015, of an above-average statewide temperature.

Alaska Climate Emphasis should be based on comfort because the dress code is informal and casual. A layered technique is extremely good here. Temperatures in Alaska during the summer range from 60°F-80°F. Nighttime and early mornings are cooler, from the 40's - 50's. Late August and September departures could encounter cooler temperatures and slightly fewer hours of sunlight, as fall arrives early at these latitudes.

Alaska Temperatures The climate of Alaska is determined by average temperatures and precipitation received statewide over many years. The extratropical storm track runs along the Aleutian Island chain, across the Alaska Peninsula, and along the coastal area of the Gulf of Alaska which exposes these parts of the state to a large majority of the storms crossing the North Pacific. The climate in Juneau and the southeast panhandle is a mid-latitude oceanic climate in the southern sections and a subarctic oceanic climat

Impacts of climate change Impacts of climate change. Over the period 1948 to 2013, the average annual temperature in Canada has warmed by 1.6 °C (relative to the 1961-1990 average), a higher rate of warming than in most other regions of the world. Increased winter and spring temperatures have contributed to this warming trend to a greater degree than other seasons.
