Overview

  • Several Bay Area cities, including Oakland, San Jose, and Half Moon Bay, broke daily high-temperature records on March 24, with more records likely on March 25.
  • The heat wave, driven by a high-pressure system preventing marine cooling, has brought the hottest Bay Area temperatures since October 2024.
  • Beach hazard warnings, including risks of sneaker waves and rip currents, remain in effect through Tuesday night along the Pacific Coast.
  • A cooling trend is forecast to begin on March 26, with temperatures dropping to seasonal norms and light rain possible in parts of the region.
  • Meteorologists are monitoring the potential for a rare atmospheric river to bring significant rain to the Bay Area by the end of March or early April.
