Climate

The name Tatlayoko is derived from the Tsilhqot'in language and means "lake of the big winds." [2] True to its name, the community is windy throughout the fall and winter as the warm Chinook winds blow up the valley. The Chilcotin Plateau is known for being extremely cold in the winter, but Tatlayoko Lake is an exception thanks to its proximity to the mild Pacific Ocean. While the coastal winds bring the community relatively mild winters, the mountains block most of the coastal precipitation, leaving the community comparatively dry.

In relation to the nearby community of Tatla Lake and indeed the rest of the Chilcotin Plateau off to the east, Tatlayoko Lake tends to be wetter in the winter and drier in the summer. Tatlayoko Lake has a continental climate (Dfb), bordering on a subarctic climate (Dfc).

gollark: Oh, so you're saying that inductively safety is *always* 0?
gollark: No, none *will ultimately be* safe, not none *can be* safe.
gollark: It says "for all x, as time tends to infinity, safety of x tends to 0".
gollark: That is NOT what that says.
gollark: =tex \forall x . lim_{time \rightarrow \infty} safety(x) = 0
