Winds blow from the south in coming days, which should mean less smoke over time.

Important life lesson: Don’t say everything you’re thinking. Even so, maybe, instead of blaming Canada for “ruining Minnesota’s summer” with wildfire smoke, we help them battle these Delaware-size blazes upwind? I know, what a crazy thought.

There are steps you can take to lower wildfire smoke inhalation, especially the PM2.5 pollution that poses greatest risk. Turn your home HVAC system to “recirculate” so you’re not drawing outdoor air into your home. Consider a HEPA air purifier, which works for one to two rooms. Don’t add to indoor pollution with candles, incense, fireplaces or smoking. Keep your vehicle’s ventilation set to “recirculate” as well. Close windows and vents. Studies have shown that PM2.5 levels inside a well-sealed vehicle can be 3,070% lower than ambient outdoor levels.

Winds blow from the south in coming days and that should mean less smoke over time, with a dry sky into Sunday. Next week brings spotty thunderstorms and sticky 80s.

Smoke stinks but at least it’s comfortable. This too shall pass.
