Ketchikan has no dry season — rain falls in all twelve months, and a normal year brings about 150 inches of it. The wettest stretch is usually late summer into fall, September and October.
On 1 December 2024 the airport measured 6.38 inches of rain in a single day, a record, during the storm that set off the fatal Third Avenue Bypass landslide. How fast the rain falls can matter more than the yearly total — which is why this page is a running tally, never a hazard signal.
