Arctic Climate: Cold but Milder Than Expected

Despite its location deep within the Arctic Circle, Svalbard’s temperatures are relatively mild due to the Gulf Stream. However, conditions remain extreme, with strong winds and sudden changes throughout the year.

• Winter (November–March): Temperatures range from -5°C to -30°C (-23°F), with polar night lasting from late October to mid-February.
• Spring (April–May): Days grow longer, and temperatures rise to around -15°C to 0°C (5°F to 32°F).
• Summer (June–August): The midnight sun shines 24/7, with temperatures between 3°C and 10°C (37°F to 50°F).
• Autumn (September–October): Rapid cooling begins, with snow returning by October and temperatures dropping below freezing.

Important Weather Considerations

• Wind Chill Factor: Strong Arctic winds can make the temperature feel much colder than recorded.
• Fast-Changing Conditions: Weather can shift within minutes, from clear skies to a blizzard-like whiteout.
• Low Humidity: The dry climate reduces frostbite risk but can cause dehydration—drink water frequently.

Essential Packing List

Svalbard’s extreme weather demands proper Arctic gear year-round.

• Insulated, Windproof Clothing: Thermal base layers, fleece mid-layers, and a waterproof outer shell.
• Protective Accessories: Gloves, balaclavas, and insulated boots to protect against frostbite.
• Portable Power Banks: Cold weather drains batteries quickly—keep electronics charged and protected.

Weather Safety & Travel Tips

• Respect the Cold: Frostbite can occur within minutes in extreme conditions—cover exposed skin at all times.
• Travel with a Guide: For safety, never venture outside Longyearbyen alone, especially in winter.
