North Cascades: Wildfire Smoke May Affect Air Quality

If you're planning a trip to North Cascades, there's one more thing on your checklist right now: smoke. Wildfires are burning across the region, and the park warns that smoky air is to be expected as long as these fires keep running. This isn't a closure alert, but it's a caution worth taking seriously before you head out to hike.

Smoke travels far and settles into the valleys. A hazy sky, the smell of burning, a milky horizon are all signs that the air has picked up particles. Park officials recommend taking precautions for any outdoor activity when smoke is heavy. Put simply, when the air gets thick, you ease off.

Here's how we'd adjust a plan in these conditions. Check the air quality first thing in the morning, before you pick your route. Stick to short hikes with modest elevation gain, since hard effort makes you breathe harder and take in more particles. Carry plenty of water and plan an exit, a spot where you can turn back without regret if visibility drops or your throat starts to sting.

Some people need to be extra careful. Kids, older adults, and anyone with respiratory trouble feel the effects of smoke sooner than others. For them, a day with very heavy air goes better indoors or in an area that's been spared than on a hard climb.

The good news is that smoke moves. A socked-in day can turn into clear skies as soon as the wind shifts. Stay flexible with your schedule and keep a few backup activities in your pocket.

To sort out the rest of your visit, the best seasons, the entrances, and the standout hikes, lean on the North Cascades park guide. You'll find everything you need to build a trip that holds up, whatever the fire weather brings.
