Best Time to Visit Alaska in Summer: Weather, Activities & Deals

I've always believed that the greatest time to travel to Alaska is in the summer. With so much daylight, the days seem to go on forever, the temperature is perfect—neither too hot nor too cold—and breathtaking scenery awaits you around every corner. I'm always in awe of Alaska in the summer, whether I'm hiking a path, observing whales, or simply admiring the scenery.
Summertime in Alaska is my favorite time of year to visit because of the pleasant weather and long days, which allow you more time to explore. For observing wildlife such as eagles, bears, and whales in action, this is the ideal time of year. Additionally, all parks, trails, and excursions are open and ready for exploration. Alaska's summers provide the perfect balance of fun and nature, whether you want to experience local festivals, hike in the mountains, or cruise past glaciers.
Here is a true sense of what an Alaskan summer is like, in case you were wondering.
Weather? Not bad. Nights cool off to the 40s or 50s, which is wonderful after a long day out, and most days are between the 60s and even 80°F.
Sunshine? Never-ending. Depending on where you are in June, daylight extends to 19 to 22 hours around the solstice.
Animals? The ideal time to see it is in the summer. Although they first appear in May, bears are most active in July. Moose? They will appear at any time.
Hiking and fishing? It's unbeatable. By May, low paths are clear, and by June, most mountains are prepared. Whether you're on the beach or by a river, fishing is terrific throughout the summer.
Mosquitoes? Yes, they are present, but only from the beginning of June until the beginning of August. You'll be alright if you bring mosquito repellent.
The northern lights? If you want a chance to view them, you'll have to wait until the middle of August. Until then, summer nights are simply too bright.

September: Shoulder season, when prices are lower and crowds are less. Bugs are mostly gone as fall colors peak. By mid-month, there is a chance to view the Northern Lights. Shorter, cooler days, but occasionally warm "Indian summer"
October: The month's first warm days (about 50°F) are followed by cooler temperatures, less daylight, and snow on the mountains. Better suited for more sedate, off-peak excursions than traditional summertime pursuits.
November: Colder temperatures (20–30°F) and shorter days (8:30 AM–6 PM in Anchorage). The late accumulation of snow limits winter activities. Excellent for viewers of the Northern Lights who are prepared to withstand cold temperatures.
December: Anchorage has very little daylight (9 AM to 3:30 PM). Towns are illuminated by Christmas lights and thick snow, perfect for winter activities. Long, chilly evenings are ideal for seeing the aurora.
