San Francisco, CA – A heat advisory remains in effect across the Bay Area and Central Coast, bringing elevated health risks through Friday evening.
According to the National Weather Service in San Francisco, temperatures are expected to reach the low to mid-90s in inland areas, while coastal regions will see highs in the 80s. The advisory is in place until 8 p.m. PDT Friday.
Forecasters say the prolonged stretch of above-normal heat will intensify impacts over time, particularly for individuals without access to cooling or adequate hydration. Interior portions of the Central Coast could approach the upper 90s by late week.
Overnight lows in the upper 50s to low 60s may offer some relief in lower elevations, but higher elevations are expected to retain more heat overnight. Coastal areas may cool slightly faster, though conditions remain warmer than typical for March.
The National Weather Service warns that the cumulative effect of consecutive hot days increases the likelihood of heat-related illnesses. Vulnerable populations, including older adults, outdoor workers, and those without air conditioning, face heightened risk.
Officials urge residents to stay hydrated, limit strenuous outdoor activity to cooler parts of the day, and wear lightweight clothing. Vehicles can reach dangerous temperatures quickly, and children or pets should never be left unattended.
Commuters and outdoor workers may experience increased fatigue during peak afternoon heat.
