June Weather in Juneau
Is June Right for You?
Advantages
- Peak whale watching season - humpback whales are most active in June with 90% sighting rates on tours, feeding heavily before southern migration
- Longest daylight hours of the year with nearly 19 hours of daylight (sunrise 4:30am, sunset 11:30pm) giving maximum time for outdoor activities
- Wildflower bloom reaches its peak on alpine trails, with lupines, fireweed, and alpine forget-me-nots creating spectacular mountain meadow displays
- Warmest weather for glacier viewing and ice cave exploration - stable temperatures make helicopter tours and glacier trekking most comfortable and accessible
Considerations
- Highest cruise ship traffic with 4-6 ships docking daily, creating crowds of 8,000-12,000 additional visitors downtown between 7am-5pm
- Premium pricing across accommodations and tours - hotel rates 40-60% higher than shoulder seasons, whale watching tours peak at $180-220 per person
- Limited restaurant availability downtown during peak lunch hours (11am-2pm) due to cruise passenger volume overwhelming local dining capacity
Best Activities in June
Whale Watching Tours
June offers the absolute best whale watching in Alaska with humpback whales feeding intensively before migration. Waters are calmest, weather most stable, and sighting rates hit 90%. Early morning tours (6:30am-7am departure) avoid cruise crowds and offer better wildlife encounters. Orcas, Steller sea lions, and harbor seals are also highly active.
Mendenhall Glacier Helicopter Tours
June's stable weather creates ideal conditions for helicopter glacier tours with 85% flight completion rates. Snow coverage is perfect for glacier landings, ice caves are accessible but stable, and visibility is typically excellent. Wildflowers bloom on nunataks creating impressive aerial photography opportunities.
Alpine Hiking and Wildflower Viewing
June is peak wildflower season on Juneau's alpine trails. Mount Roberts, Perseverance Trail, and Mount Jumbo offer spectacular lupine and fireweed displays. Long daylight hours allow for extended hiking - you can start trails as late as 6pm and still have 5+ hours of daylight. Snow has cleared from most trails below 900m (2,950 ft).
Salmon Fishing Charters
Early June marks the beginning of king salmon runs with fish averaging 15-25 kg (30-55 lbs). Charter success rates are highest in June before fish disperse to spawning streams. Coho salmon also begin running mid-month. Calm seas and extended daylight make for comfortable 6-8 hour fishing experiences.
Kayaking in Protected Fjords
June offers ideal sea kayaking conditions with calmer waters, minimal wind, and active marine wildlife. Auke Bay and Fritz Cove provide protected paddling with frequent seal, otter, and whale encounters. Water temperature reaches seasonal highs around 12°C (54°F), making immersion less problematic.
Tracy Arm Fjord Cruises
June provides optimal conditions for Tracy Arm fjord exploration with stable weather, active glacial calving, and peak iceberg viewing. Sawyer Glaciers are most photogenic with fresh snow contrast. Harbor seals pup on icebergs in June, and black bears are frequently spotted on shorelines feeding on early vegetation.
