Air Quality Map

In addition to the wildfire smoke forecast maps, you can now view the real-time air quality index on OpenSummit to help you plan your next adventure.

The 'Air Quality Index' map overlay is the current US EPA PM2.5 air quality index from PurpleAir sensors. Shown as the 10-minute average for the past 24 hours.

Here is an example of the air quality index for Lake Tahoe, California on August 24, 2021.

The higher the AQI value, the greater the level of air pollution and the greater the health concern.

View the air quality map on any device by upgrading to All-Access for $29.99/year (Single) or $39.99/year (Group). The subscription includes 5-day hourly forecasts, estimated trail conditions, and much more.
