The sky looked like a filter, the air quality number looked like a warning, and only one of those two things was actually telling me the truth.
There’s a particular kind of morning during bushfire season where the sky turns this strange, striking orange-grey and everyone’s phone fills up with photos captioned some version of “apocalyptic,” and I’ll admit my first instinct that day was purely aesthetic — I wanted to get a run in specifically because the light looked incredible. That instinct was, it turns out, exactly backwards.
I checked the air quality reading before I laced up, mostly to see if it matched the drama of the sky, and it did — well into the range where outdoor exercise is actively discouraged, smoke from fires a good distance away having drifted in and settled low over the whole region overnight. The sky’s color and the actual danger were, for once, telling the same story, which isn’t always the case with smoke. Sometimes it looks worse than it is. That morning it looked exactly as bad as it was.
I moved my run to the following afternoon instead, once the reading had dropped back into a normal range, and spent the missed morning doing something considerably less photogenic on a treadmill indoors, which felt like a genuine letdown at the time given how good the light outside looked through the window the whole time.
A running friend who went out anyway that morning, camera in hand more than trainers on feet, spent the next two days with a scratchy throat and a cough she was fairly sure wasn’t unrelated. Smoke doesn’t announce itself the way rain does — you can’t feel your lungs working harder in the moment the way you’d feel getting wet, and by the time it’s obvious, you’ve already had the exposure.
I check the air quality number now before every run during fire season, not just the sky, because the sky can lie in either direction and the number generally doesn’t — wildfire smoke especially can look mild while the reading says otherwise. If you’ve got running friends who make the call purely off how the sky looks, this is worth sending along — a dramatic photo and a safe run are not the same decision. It’s the same clear-sky-doesn’t-mean-safe lesson a beach day with my nephews taught me, just with rip currents instead of smoke.
