Bay Area Faces Rare 'Quadfecta' of Extreme Weather: Extreme Heat, Wildfire Risk, Flooding, and Dangerous Waves

The Bay Area is facing a convergence of extreme weather events dubbed a "quadfecta," including triple-digit temperatures, elevated wildfire danger, high tides, and sneaker waves. Inland areas like Concord, Napa, and Sonoma are expected to reach 100°F+, while coastal areas face dangerous surf conditions. The weather pattern is driven by a high-pressure ridge that is keeping the marine layer away, leading to hot overnight temperatures and increased fire risk. The combination of heat, fire danger, coastal flooding, and powerful waves creates a uniquely risky start to the summer season across the region.
