San Diego may be exposed to rising sea levels, but its coastal location gives it a host of advantages. According to research from Sarah Kapnick, a climate scientist at Princeton University, San Diego may have the most ideal weather of any US city.
After studying the number of "mild weather" days — those suited for outdoor activities, with low precipitation, low humidity, and temperatures between 64 and 86 degrees Fahrenheit — Kapnick found that US summers are becoming hotter and more humid. By the end of the century, she discovered, cities in West Virginia, Ohio, Indiana, Nevada, Arizona, Utah, and New Mexico could lose weeks of mild weather due to climate change.
This wasn't the case in San Diego, which currently boasts 180 days of mild weather per year compared to 157 in Los Angeles, 83 in New York, and just 76 in Boston. In the future, the city could see even more pristine weather conditions.
Kapnick's study predicts that San Diego will gain three mild days per year by the end of the century. Perhaps the main concern for San Diego is a loss of precipitation, which can contribute to wildfires. That's a major worry, but one that nearly all California cities will have to face.
