Gets to about -20C (-4F) here for a couple weeks about twice a winter.
The harbour and main channels don't freeze, but in bays with creeks fresh water that floats on top of the salt water freezes. Our boat is on an outer finger in the marina and never sees ice, but boats closer to shore get frozen in every year.
It's a weird place weather wise. Lots of marine weather marches up the channels from open water 90 miles away as the crow flies (there ferns growing in the moss growing on the branches of trees) while cold air from inland flows down the valley during cold snaps and from the surrounding mountains.
Kitamaat means People of the Snow in the local Haisla First Nations language, so it's had a bit of a reputation for thousands of years.
I've seen mushrooms and slugs in January, maples turning red in July, and snow in the fields around town for six months without melting. There is no such thing as 'normal' weather here.
