Spare the Air Alert Hits Pleasanton as Temperatures Near 100°F

On Wednesday the Bay Area Air Quality Management District sounded the alarm for Pleasanton, placing the city in a Spare the Air alert. The warning comes as the forecast nudges the mercury up to about 101°F, with the rest of the Tri‑Valley likely to see similar highs.

Why the alert? A mix of scorching daytime temperatures, barely any surface wind and a delayed sea breeze are set to trap ozone and other pollutants close to the ground. The Eastern Zone of the Air District—where Pleasanton sits—could see an Air Quality Index of 101, which the EPA labels “unhealthy for sensitive groups.” That means children, seniors, and anyone with heart or lung conditions should take extra precautions.

Practical steps are simple but crucial. If you have to be outdoors, aim for the early morning when ozone levels are lower, and keep exertion to a minimum. Drive less if you can—carpool, hop on transit, or simply stay home. If you must fill up your tank, do it after sunset to reduce emissions that fuel smog. And please, no idling.

For those looking for a place to escape the heat, the Pleasanton Library on Old Bernal Avenue opens its doors from 1 p.m. to 9 p.m. as an unofficial cooling spot. The city also stands ready to designate additional cooling centers if conditions worsen.

The National Weather Service echoes these recommendations: stay out of direct sun, drink plenty of water, and shift strenuous chores to the cooler parts of the day. Outdoor workers should take frequent breaks in shade or air‑conditioned spaces.

Don’t forget the little ones and pets. Never leave children or animals in a parked car, even with windows cracked—temperatures inside can soar far above the outside heat in minutes.

After the peak on Wednesday, the mercury should ease a touch: Thursday is expected to top out near 97°F, and by Friday highs will dip into the 80s. Still, overnight lows will linger in the mid‑60s to mid‑70s, so nighttime relief will be modest.
