The state's vast size and geographic diversity mean that temperatures can range from extremely cold in the interior regions to relatively mild along the coastal areas.
Interior Alaska experiences a subarctic climate with extreme temperature variations.
- Winter: Temperatures can plummet to -40°F (-40°C) or colder. The record low for Alaska was set in Prospect Creek Camp in 1971 at -80°F (-62°C).
- Summer: Surprisingly, summer temperatures can soar to the 90s°F (30s°C). Fairbanks, the largest city in the interior, often sees summer highs in the 70s and 80s°F (20s to 30s°C).
The coastal regions, influenced by the Pacific Ocean, have a more moderate climate.
- Southeast Alaska: Known for its maritime climate, Southeast Alaska, including cities like Juneau and Ketchikan, enjoys milder winters, with temperatures rarely dropping below 20°F (-6°C). Summers are cool and wet, with temperatures typically ranging from 50°F to 70°F (10°C to 21°C).
- Southcentral Alaska: Anchorage, located in Southcentral Alaska, experiences mild temperatures compared to the interior. Winter temperatures average between 5°F and 30°F (-15°C to -1°C), while summer temperatures range from 55°F to 70°F (13°C to 21°C).
Western Alaska, facing the Bering Sea, has a maritime climate with cool, wet summers and cold, windy winters.
- Winter: Temperatures generally range from 5°F to 20°F (-15°C to -6°C).
- Summer: The temperatures range between 40°F and 60°F (4°C to 16°C).
Arctic Alaska, north of the Arctic Circle, experiences the harshest climate.
- Winter: Temperatures can drop to -30°F (-34°C) or lower, with prolonged periods of darkness.
- Summer: Summer brings the midnight sun, and temperatures can occasionally reach 50°F (10°C), but they usually stay in the 30s and 40s°F (0°C to 10°C).
Winter in Alaska is characterized by long nights and short days, especially the further north you go. The interior and Arctic regions experience the coldest temperatures, often below -20°F (-29°C). Coastal areas are more temperate but still cold.
Spring is a transitional season in Alaska. Temperatures slowly begin to rise, and daylight hours increase. In the interior, temperatures can range from 20°F to 40°F (-6°C to 4°C), while coastal regions see milder temperatures ranging from 30°F to 50°F (-1°C to 10°C).
Summers in Alaska can be surprisingly warm, especially in the interior. The long daylight hours result in extended periods of warmth. Coastal regions remain cooler but still pleasant.
Fall brings a rapid drop in temperatures, especially in the interior and Arctic regions. Snow can start as early as September, and temperatures can range from 30°F to 50°F (-1°C to 10°C) in the coastal areas, while the interior sees temperatures from 20°F to 40°F (-6°C to 4°C).
Latitude plays a significant role in Alaska's temperatures. The further north you go, the colder it gets, especially during the winter months. The Arctic Circle marks a significant climatic boundary where the sun does not rise above the horizon for parts of the winter and does not set for parts of the summer.
Elevation also affects temperature. Higher elevations, such as those found in the Alaska Range, experience colder temperatures year-round. Denali, North America's highest peak, has permanent glaciers and temperatures that can drop to -75°F (-59°C) at its summit.
Proximity to large bodies of water, like the Pacific Ocean and the Bering Sea, moderates temperatures. Coastal areas have milder winters and cooler summers compared to the interior regions.
- Lowest Temperature: The lowest recorded temperature in Alaska was -80°F (-62°C) at Prospect Creek Camp in 1971.
- Highest Temperature: The highest recorded temperature was 100°F (38°C) in Fort Yukon in 1915.
Climate change is impacting temperature patterns in Alaska. The state has been warming at twice the rate of the global average over the past 50 years. This has resulted in:
- Warmer Winters: Winter temperatures have been rising, leading to shorter seasons of ice and snow.
- Thawing Permafrost: Rising temperatures are causing permafrost to thaw, leading to ground instability and impacting infrastructure.
- Changing Ecosystems: Warmer temperatures are affecting wildlife and plant species, altering migration patterns and growing seasons.
For the most accurate and up-to-date temperature information, it is advisable to consult weather websites and local forecasts. Websites like the National Weather Service and Weather.com provide real-time data and forecasts for specific locations within Alaska.
Urban areas like Anchorage can experience the urban heat island effect, where temperatures are slightly higher than the surrounding rural areas due to human activities, buildings, and infrastructure.
Indigenous communities in Alaska are acutely aware of temperature changes as they directly impact their traditional lifestyles, including hunting, fishing, and gathering.
The temperature has a direct impact on Alaska's glaciers. Warmer temperatures are leading to accelerated glacier melt, contributing to sea-level rise.
Temperature fluctuations in Alaska have far-reaching impacts beyond what is visible. From permafrost degradation to shifts in local ecosystems, the state's temperature dynamics are a subject of ongoing research and concern. As the world continues to monitor these changes, Alaska stands as a testament to the complex interplay between climate and environment, prompting us to ponder the future of this unique region.

Alaska, the largest state in the United States, is renowned for its vast wilderness, majestic landscapes, and frigid temperatures. The state's climate is diverse due to its immense size, ranging from temperate rainforests in the southeast to Arctic tundra in the north. Understanding just how cold Alaska can get involves exploring various regions, seasonal variations, and extreme weather conditions.

In the mid-19th century, the Russian Empire faced financial difficulties and geopolitical pressures, prompting it to consider selling its North American territories. The Crimean War had drained Russian resources, and maintaining its remote Alaskan territory became increasingly untenable. The Russian government feared that if a conflict with the United Kingdom or another power were to arise, Alaska could be easily seized. Thus, selling the territory to a friendly nation was seen as a strategic move.

Alaska and Russia are separated by the Bering Strait, a narrow passage that connects the Arctic Ocean with the Bering Sea. The closest point between the two territories is a mere 55 miles (88.5 kilometers) apart. This minimal distance underscores the geographical proximity and historical connections between the regions.
