Summary: When to Visit Alaska
Alaska can be visited year-round, depending on your preferences. High season (June–August): 20 hours of sunlight, all activities available, high prices, book a year in advance. Low season (May–September): solitude, lower prices, some parks closed. Winter (October–April): spectacular Northern Lights, extreme cold, unique winter experiences.
When is the best time to travel to Alaska?
If you’re looking for the midnight sun and a kayaking trip on the turquoise waters of glacial rivers, then visit during peak season, from June through August. The season is very short, so you’ll need to book your trip and accommodations well in advance. There’s no room for last-minute plans!
- The roads are 100% passable
- Access to all outdoor activities
- 20 hours of sunlight per day in June
- It’s salmon migration and wildlife viewing season
- Average temperature: 15–21 °C (59–70 °F)
Budget: Rates are at their highest. Expect a 20–30% increase in costs compared to May or September for lodging and activities.
In summary: This is the best time to make the most of Alaska and its natural beauty. As a result of this (all too) short season, prices are higher than during the rest of the year.
