A few of you have asked about air quality websites. I do the same thing that most of you probably do, search the web. Look for official sites like Colorado.gov.
I also like to look at satellite because smoke conditions change fast. The RAMMB Slider (google it) offers a range of satellite options and you can zoom in. The afternoon and early evening is the best time to look because that’s when fires are most active. The satellite won’t necessarily tell you how bad it is at ground level, but you can see which smoke plumes are activity growing and where they are going.
