Wildfire Smoke Is Back in the Fraser Valley — Here’s What to Actually Do This Week

Fraser Valley smoke has made the sky’s looked hazier than usual lately, it’s not your imagination. Wildfire smoke has triggered repeated air quality warnings across the Fraser Canyon and BC Interior throughout July. With nearly 100 active wildfires burning across the province, this summer is expected to remain smoky. Here’s what’s actually happening and what to do about it.

Fraser Valley wildfire smoke continues to affect air quality across the region, making it important to stay informed and follow the latest health advisories.

Fraser Valley Wildfire Smoke: What’s Actually Happening

Air quality warnings have been in and out of effect across the Fraser Canyon, the Interior, and parts of the Lower Mainland for weeks now, driven by wildfires including a significant one near Boston Bar. Wildfire smoke in the Fraser Valley can change quickly depending on weather conditions. A clear morning doesn’t guarantee a clear afternoon. Always check current air quality instead of relying on yesterday’s conditions.

You can check the latest air quality and wildfire updates on the BC Wildfire Service website and Environment and Climate Change Canada’s Air Quality page.

Fraser Valley wildfire smoke can spread quickly as weather conditions change, so checking daily air quality updates is the best way to stay informed.

Why It’s More Than Just an Inconvenience

A recent BC Lung Foundation report puts real numbers behind what wildfire smoke does to the body: Fine particulate matter from wildfire smoke can irritate your airways immediately. Long-term exposure may contribute to heart and lung damage. The report also links wildfire smoke to nearly 1,900 premature deaths in BC each year. The last three fire seasons have all come in above the 10-year average for area burned, and each one has touched nearly every region of the province in some way — this isn’t a one-summer blip.

Fraser Valley smoke can affect anyone, but children, older adults, pregnant people, and those with heart or lung conditions are at greater risk during poor air quality days.

What To Do During a Fraser Valley Wildfire Smoke Warning

During periods of Fraser Valley smoke, following these precautions can help reduce your exposure and protect your health.

• Scale back outdoor activity. Postpone or shorten strenuous exercise and outdoor plans until air quality improves.

• Close up the house. Keep windows and doors shut, especially during peak smokehours.

• Filter your indoor air. A certified portable air cleaner or a quality HVAC filter can improve indoor air. If you don’t have one, the BC Centre for Disease Control provides instructions for building a simple DIY air cleaner using a box fan and a furnace filter.

• Prioritize cool over fresh air if it’s also hot out. If your home isn’t air conditioned, spending a few hours somewhere that is — a library, community centre, or mall — is a reasonable option during a combined heat-and-smoke event.

• Know the warning signs. Difficulty breathing, chest pain or discomfort, or a severe cough are reasons to contact a doctor, walk-in clinic, or emergency department. For anything urgent, call 911. For general health questions, HealthLink BC (811) is available any time.

Wildfire season is also a good time to review your home’s emergency preparedness. If you are checking your insurance coverage before severe weather, read our guide on Water Damage Coverage in BC: What to Check Before Renewal to better understand what your policy covers and avoid unexpected costs.

As Fraser Valley smoke conditions can change quickly, check official air quality updates each day before planning outdoor activities.
