Extreme Heat

Nationwide, extreme heat is one of the deadliest climate related hazards and one that already affects San Mateo County. High heat days and heat waves are experienced more frequently in recent years,  in addition to years of drought conditions. This may be even more impactful because San Mateo County has one of the lowest percentages of homes with air conditioning units in California, according to the Home for All and Climate Ready SMC joint Housing and Climate Readiness in San Mateo County Toolkit (PDF).

Heat Impacts on Health and Infrastructure

As average temperatures rise, projections for San Mateo County anticipate an increase in the frequency and duration of extreme heat events due to climate change. These events may impact public health and the viability of transportation networks.

Populations anticipated to have increased vulnerability include: older adults, infants & children, pregnant persons, individuals with disabilities, people without housing, outdoor & manual workers, athletes

The San Mateo County Sustainability Department partnered with Stanford Future Bay Initiative and City Systems to better understand the implications of future climate conditions on heat projections through the San Mateo County Extreme Heat Dashboard. The following map shows projections for average number of high heat days (above 85°F), by jurisdiction over the near-term (2020-2029) and long-term (2016-2045). Modeling suggests the average number of high heat days will increase for many jurisdictions with greatest impacts expected in Atherton, East Palo Alto, Menlo Park, North Fair Oaks, Redwood City, San Carlos, and Woodside.

Heat Adaptation Strategies

The past Climate Ready SMC initiative worked with cross-sector and community leaders to identify adaptation strategies to extreme heat, including tree planting and urban forestry, updated building codes, cooling centers and multilingual communication. Learn more through the Climate Ready SMC Extreme Heat and Public Health Factsheet (PDF).

Related to transportation, adaptation strategies included heat sensors for rail lines, shading for transit stations, increased service frequency during high heat, and increased funding for transit and road maintenance. Learn more through the Climate Ready SMC Extreme Heat and Transportation Factsheet (PDF).

Fixit Clinic @ Half Moon Bay Library
Mar
22

Fixit Clinics are fun community-based workshops where neighbors, friends, and families work collectively to learn how to repair broken items. We’ll provide a workspace, specialty tools, and volunteer Fixit Coaches to help you troubleshoot and provide routine maintenance to your household items and appliances! Register at https://bit.ly/itemcheckin

Interested in being a Fixit Coach?
It’s easy! Provide participants with 1) guidance on tools and 2) encouragement to investigate their broken item. Let them talk about how they used it and how it broke. That often provides valuable hints as to what’s wrong. See how much you can do without actually handling the item. Empower the item’s owner to do the troubleshooting and disassembly. Register to be a Fixit Coach here.

This event is hosted in partnership with the San Mateo County Libraries.
