December's average high runs near 39°F, and Sisters receives a real, disclosed 35 inches of snowfall annually on average, with monthly peaks near 12-14 inches in December and February -- genuinely more in-town snow than Bend, reflecting Sisters' closer position to the Cascade Range foothills.

First Street cites 2,469 Sisters-area properties with wildfire risk over the next 30 years, though no historic event was recorded 1984-2021 -- rising regional temperatures and drier conditions are cited as creating increasingly prime wildfire conditions going forward.
