Weather information for the Lassen Volcanic NP area is provided below. Average temperatures, climate details and current forecasts are included!
Climate
Lassen National Park is very much an alpine park and the weather reflects this. Below 7,500 feet elevation, the summers are mildly warm and the winters are cool to cold. Rise above this elevation and the winters become harsh and the summers cool. Precipitation in Lassen is quite high - in fact, the area around the park's Lake Helen is possibly the snowiest place in California.
