This summer, be part of a campaign to map San Francisco’s urban heat islands to discover which neighborhoods become the hottest during extreme heat events.
In San Francisco, extreme heat events are increasing in frequency and intensity, with significant, cascading, and compounding impacts on public health. And while all San Franciscans are vulnerable to the health impacts of extreme heat, some neighborhoods and communities may be disproportionately impacted. Urban heat islands are areas that can be up to 20 degrees hotter than nearby neighborhoods.
The Urban Heat Watch is an action to map heat in San Francisco’s neighborhoods to understand how our built environment: our green space and our tree canopy, our pavement and our skyscrapers, can create neighborhood-level heat islands that fuel health impacts.
