Be Alert! Your eyes are your best tools to determine if it’s safe to be outside during smokey conditions

Smoke forecasts are dependent on predicted fire growth and weather. If conditions change unexpectedly, impacts could occur. When visibility starts to go below 5 miles, sensitive groups should minimize outdoor activities. Everyone else should minimize prolonged or physical activity outdoors. Refer to the Smoke and Health Tab on the Idaho Smoke Information Blog for additional health information.

Your eyes are your best tools to determine if it’s safe to be outside. Even if you smell smoke, the air quality may still be good.

Wildfire smoke persist through the weekend throughout Idaho. Northern and central Idaho will likely continue to be hit hardest with poor air quality conditions. Some improvements possible in southcentral and southeast Idaho. Fires in Montana, Oregon, and British Columbia remain active and contributing to poor air quality conditions.


  1. The smoke conditions in the Lost River Valley of Idaho are in the range of Unhealthy and Very Unhealthy depending on the time of day and wind direction. Since we don't have air quality monitoring equipment in this area I pay close attention to the visibility between my home and known distance landmarks. Four or Five years ago the visibility to a landmark 1/4 mile away was greatly diminished placing the air quality in the valley in the Hazardous range. I appreciate your website as it helps me monitor level of risk in our area which I then communicate back to our workforce in hopes of protecting their health and safety.

  2. Thank you for sharing your observations and helping get the word out about the conditions in your area. The visibility chart is easy to use and provides instant information to help make decisions for protecting your health as well as others. Its good to hear that it is helping.

  3. Are there any moderate to safe levels good for camping within a 3 hour radius from Boise?

  4. Check out our map but be cautious when deciding. Unfortunately while there may be some areas of clearing now the low level winds just tend to push all the smoke around and just change the areas of the biggest buildup for now.
