California October 2023 Heat Wave: When Will It Finally End?

A fall heat wave in California is expected to bring temperatures up to 15 degrees above normal, potentially breaking heat records. Heat advisories are in effect for Southern and Northern California, with temperatures reaching the 90s in some areas and above 100 in the low deserts. The unseasonably hot weather raises concerns for heat-related illnesses, particularly among vulnerable populations. Tips for staying safe during the heat wave include staying hydrated, visiting cooling centers, and checking on vulnerable individuals. Climate change is contributing to the increased frequency and intensity of heat waves, with greenhouse gas emissions and warming ocean waters playing a role. Extreme heat is a serious threat, disproportionately affecting the poor, elderly, and marginalized communities. Temperatures are expected to cool on Friday.
