Lassen Volcanic National Park
Tonight at Lassen Volcanic National Park
Lassen Volcanic National Park is home to steaming fumaroles, meadows freckled with wildflowers, clear mountain lakes, and numerous volcanoes. Jagged peaks tell the story of its eruptive past while hot water continues to shape the land.
Weather & conditions
Weather at Lassen can vary dramatically throughout the year. Average January temperatures are a high of 40.4 °F (4.7 °C) and a low of 20.8 °F (-6.2 °C). Average July temperatures are a high of 88.4 °F and a low of 49.8 °F. Temperatures reach 90 °F or higher on an average of 36.9 days, and drop to 32 ° or lower on an average of 164 days days annually.
What this latitude gives you
From 40.5° north, anything above declination +49.5° is circumpolar here: it never sets, so it is available on every clear night of the year. Anything below declination -49.5° never clears the horizon at all.
Astronomical darkness lasts through every night of the year here, including midsummer, which makes this a rare site for a June or July imaging trip.
We do not hold a measured Bortle class for this site, so treat the sky as unknown until you have taken a reading of your own.
