Fire Update, August 20, 2021

August 20, 2021 Posted by: Yosemite Fire Information

As of August 19th, Yosemite has had 43 fires started by lightning and 11 human-caused fires for the 2021 calendar year. The park is utilizing a mix of strategies to suppress, monitor, or contain these fires throughout Yosemite's fire-adapted ecosystems. Currently there are four active fires, and these have all been contained or in the process of being contained using control lines and natural barriers.

Fire management actions have adhered to Minimum Impact Suppression Techniques (MIST). This minimizes impacts in the wilderness while allowing the healthy ecological effects of natural fire. The overall strategy for managing all wildland fires is to provide for the safety of employees and the public and protect and enhance natural and cultural resources.

Smoke may be present in parts of Yosemite National Park due to other regional fires in California. Please see below for links to air quality and weather in Yosemite.
