San Diego summers, like the rest of the U.S., are getting hotter

San Diego's average summer temperature has risen by 3. 2°F since 1970, aligning with a national trend identified in a report by Climate Central. This study found that 97% of 242 U. S. cities analyzed experienced average summer temperature increases of 2.

6°F. Vulnerable populations, including children, pregnant women, the elderly, and the homeless, face increased health risks due to these rising temperatures. The National Weather Service anticipates that summer 2025 will likely be hotter than normal for much of the country, including southern California. The analysis employed NOAA data, defining summer as the months of June through August. This alarming trend underscores the pressing need for public health measures and climate action.

As communities grapple with these changes, local governments may need to implement strategies to protect vulnerable groups. Continued research and monitoring will be essential in addressing the impacts of climate change on public health.
