Post-season — prices falling after the travel period, beaches and attractions quieter.
October is the coldest winter month in Alaska (Juneau) — with highs of only 9°C (48°F), it holds little appeal for sun-seekers. Better travel in May, June, July, August, and September.
Temperatures reach a maximum of 9°C (48°F) during the day and drop to 5°C (41°F) at night — warm layers recommended. Peaks reach around 13°C (55°F), the coldest nights around -2°C (28°F) — frost does occur. With 3 sunshine hours per day and 17 rain days (219 mm (8.6 in)), this is one of the cloudier months. At 11°C (52°F), the water is still quite cool in October — a wetsuit may be useful.
An umbrella or waterproof jacket is essential. On rainy days, plan indoor activities like museums and markets.
The rain returns, the deciduous woods turn yellow and the cruise season ends. The town grows quieter, the salmon runs wind down and the first snow reaches the peaks. Those who bring a rain jacket and patience find low prices and dramatic cloud moods.
