THOUSAND PALMS, Calif. (KESQ) – It’s been hot and hazy across the Coachella Valley, leading to poor air quality in recent days.
Rick Miller, who often takes his dog to the David H. Ready Dog Park in Palm Springs, noticed the usual group of dog owners was thinner on Monday.

“Some friends of mine have asthma and so they don’t come on days when the air quality is bad,” Miller explained. “One of my friends is on an oxygen tank and he comes here and when the air quality is bad, he notices that it malfunctions and it overheats much quicker. He can’t stay very long.”
At times, air quality dipped into the “Unhealthy” range over the weekend. As of Monday, most of the valley is seeing “Moderate” air quality.

The Gifford Fire, which is burning over 200 miles to our northwest, has torched upwards of 65,000 acres as of Monday morning. According to the National Weather Service, our weather pattern is helping fuel westerly winds, which are funneling the smoke from that wildfire across Southern California and beyond. That haze is being pushed as far as Las Vegas!
Adam Roser, a Lead Meteorologist with the National Weather Service’s San Diego forecast office, said, “We have a trough of low pressure up to the north and then an area of high pressure over the southwest desert region. So those two pressure systems are kind of in between those, so that wind pattern is just kind of funneling some westerly winds across the area.”
A new wildfire, the Gold Fire, burning near Big Bear, is also expected to contribute to smoky conditions in the low and high deserts.
Over the weekend, the Coachella Valley also saw elevated levels of ground-level ozone, a primary pollutant in smog. This type of ozone (which is different from stratospheric ozone) is created through a chemical reaction: emissions from cars are heated on hot, sunny days, resulting in this pollutant.

Ozone in the upper atmosphere is great for us. It helps protect us from the sun’s harmful UV rays. Ground-level ozone, however, can cause breathing problems and is one of the main ingredients of the smog we’re seeing across the valley.
Mix the ozone with the wildfire smoke being funneled into the valley, and the result becomes poor air quality and hazy skies.
“We haven’t really seen a lot of, you know, windy conditions. It’s been kind of lighter winds in the atmosphere as well, so not as much movement of air. A couple of those factors in the weather can really contribute to that as well,” said Roser.
“Those hot temperatures combined with, you know, some of the smoky skies will make for poor air quality for those sensitive groups.”
Rick Miller and the dogs he’s looking after hoped the hazy skies give way to better air quality sooner rather than later.
“[These conditions are] not good because we need to get out and enjoy this, especially what’s going on in the world,” Miller said. “It’s good to have some positive things to look forward to and being outside when the weather is nice and the air is clear, it makes a big difference.”
