Fresno's Warm February: A Rare Historical Event

Fresno braces for a historic warm weekend, with temperatures nearing eighty degrees, a rare occurrence in February. Despite a dense fog advisory in the morning, the rest of the day promises mostly sunny skies. However, the warmth is short-lived, as temperatures drop back to normal sixties next week with no rain in sight.

The podcast explores the decline in foggy days, from an average of forty in the sixties, seventies, and eighties to about twenty-four now. Experts attribute this change to increased farming, particularly orchards like almonds, pistachios, and walnuts, which have replaced row crops. These orchards hold less winter moisture, hindering fog formation. Additionally, Fresnos average winter overnight lows have risen by two point four degrees in the last thirty years, making dew points harder to reach.

The recent winter, however, bucked the trend with forty fog days due to an early wet start. But with current trends, foggy winters like this will become rarer.
