Juneau Weather, When to Go and Climate Information
(Juneau, Alaska - AK, USA)
Visitors to Juneau will find that the climate is described as being humid, continental and oceanic. Being located in Alaska, the capital can experience extremes of weather, with subarctic temperatures at times.
Juneau is actually not only the wettest city in Alaska, but also the warmest. Temperatures during the winter season feel fairly chilly, staying close to freezing by day and becoming icy by night, with noticeably short daylight hours due to the city's northerly setting.
When the December weather arrives, you can expect the sun to rise at just before 09:00 and then set in the afternoon, as early as 15:00 or thereabouts, meaning just over six hours of daylight at this time of the year. If you are lucky enough, the Northern Lights may appear during the dark nights, as they can sometimes be seen this far south.
