In San Francisco, heat waves are getting hotter, lasting longer, and with higher nighttime temperatures. These heat waves are having significant, cascading and compounding impacts on public health.
On the Friday of the 2017 Labor Day weekend, temperatures in San Francisco hit 106 degrees, the highest temperate ever recorded in the City and 37 degrees warmer than the average temperature for that day. The heat wave continued into Saturday, making it only the third time in recorded history that San Francisco’s temperatures hit triple digits two days in a row.
There were over 1,300 9-1-1 calls on Friday September 1st, more than double the number of calls the previous Friday and there was a 17% increase in Emergency Department visits. These health impacts are consistent with the literature: a California Department of Public Health epidemiological study of a 2006 statewide heatwave found that Emergency Department visits increased more in California Central Coast communities (like San Francisco) than anywhere else in the state.

This Urban Heat Island mapping campaign with help San Francisco target interventions towards the neighborhoods and communities that carry the greatest health burden of extreme heat by identifying which communities are particularly exposed to the hazard.

NIHHIS is an integrated information system that builds understanding of the problem of extreme heat, defines demand for climate services that enhance societal resilience, develops science-based products and services from a sustained climate science research program, and improves capacity, communication, and societal understanding of the problem in order to reduce morbidity and mortality due to extreme heat. NIHHIS is a jointly developed system by the Centers for Disease Control and Prevention (CDC) and the National Oceanic and Atmospheric Administration.
