Versatile layering for changing coastal weather
Residents should prepare for a mix of rain and snow, though totals are more manageable than in neighboring boroughs. High-quality wind-resistant layers are helpful for the coastal breezes and 25.6°F January lows. Standard Alaska winter gear is sufficient for the moderate 44.9 inches of snow.
