It’s warmer in California, with temperatures in Sacramento hitting the 70s and 80s this week.

According to the National Weather Service, hot weather can worsen air quality.

“The sun can cause chemical reactions in certain pollutants, leading to the development of smog,” the agency said on its website. He added that higher air temperatures increase chemical reactions in the air and, depending on wind speed, pollutants can disperse quickly or slowly.

In a recent study, the American Lung Association found the Sacramento area to be one of the most polluted cities with daily particles, ranking 7 out of 25. Fresno topped that list at number one.

The AQI breaks down air quality readings by its level of concern: good (0-50), moderate (51-100), unhealthy for sensitive groups (101-150), unhealthy (151- 200), Very Unhealthy (201-300) and Dangerous (301-superior).

The data is forecast for the coming days and updated hourly.
