Reduce or avoid strenuous activity

Extremely poor air quality blankets Lethbridge region, southern Alberta

Aug 2, 2026 | 11:10 AM

Some of the worst air quality that the Lethbridge region has experienced in quite some time is hovering over the area this weekend.

As of 10 a.m. Sunday morning, the Air Quality Health Index (AQHI) from Environment & Climate Change Canada for the city was measured at 10+, the highest reading on the 11-point scale.

At a very high risk, it’s strongly suggested the general population reduce or reschedule strenuous outdoor activities, especially if you have symptoms like coughing and throat irritation.

For those more at risk, who have breathing issues or a heart condition, the recommendation is to avoid all strenuous activities outdoors, until conditions change for the better.

With an extremely poor air quality, today’s Lethbridge Bulls game against the Sylvan Lake Gulls at Spitz Stadium is in a holding pattern, with a call to be made at around 12:30, 90 minutes or so before the first pitch, on whether the teams feel it will be safe to play.

For now, fans are being encouraged not to arrive early at the ballpark.

The Bulls have said they will make an announcement on their Facebook page.

The Town of Coaldale also announced late Sunday morning, that its outdoor pool and Tot Lot would be closed until further notice, due to poor air quality.

“If air quality conditions improve by early afternoon, the pool may reopen later today. If the pool does not reopen today, it is expected to reopen tomorrow, Monday, August 3, as usual, pending air quality conditions,” said a post on the Town’s Facebook page.

While air quality hasn’t been great since Friday, when much of southern Alberta was placed under either a yellow or orange alert for air quality, based on smoke drifting in from wildfires in B.C, it was, generally, at a moderate health risk.

That, however, changed early Sunday morning when the reading spiked from 5 (5 a.m.) to 10 (6 a.m.) and then 10+ an hour later, where it remained all morning.

Conditions, though, are forecast to dramatically improve on Monday dropping back down to a low-risk rating of 3.
