A Spare the Air Alert has been issued for Pleasanton and the wider Bay Area, according to the Bay Area Air Quality Management District. The alert was triggered by a combination of high temperatures, light surface winds, and a delayed afternoon sea breeze, conditions that are expected to lead to elevated smog levels.
The Eastern Zone, which includes Pleasanton and the Tri-Valley area, is projected to reach an Air Quality Index of 101. This level is classified as unhealthy for sensitive groups, such as children, older adults, and individuals with heart or lung conditions.
Residents in the affected areas are advised to limit outdoor exercise to the early morning hours when ozone levels are lower. To help reduce emissions, the district encourages people to limit driving, use public transit, carpool, refuel vehicles after dusk, and avoid idling engines.
The National Weather Service also recommended that individuals stay out of direct sunlight, stay hydrated, and shift strenuous outdoor activities to cooler parts of the day. Those working outside should take frequent breaks and seek shade or air conditioning.
Temperatures in Pleasanton are expected to peak at approximately 101 degrees. The heat is following a period of about 10 days with below-normal temperatures, particularly in inland areas. While coastal regions may see highs in the low 90s, some interior and higher-elevation locations could reach triple digits.
