The richness of the surrounding temperate rainforests, the glory of the Stikine Icefield and the abundance of the prolific salmon are all dependent on high annual rainfall and the cool temperatures of a maritime climate. The annual precipitation in Petersburg is approximately 110 inches, similar to that of the Olympic Peninsula in Washington State. Approximately half of the annual precipitation falls in the months of October, November and December.

Fortunately, clear, bright periods of sun do occur and occasionally persist for several weeks in both winter and summer. Summertime highs average about 60° F, winter temperatures range from mild to cold. Snow depths range from little or no snowfall to three feet. The wintertime lows average 20° F, though the temperatures sometimes fall to zero for short periods.

Petersburg gets about 18 hours of daylight on the longest day in the summer and about 6 hours of daylight on the shortest day in the winter.
