The extreme heat poses significant health risks, particularly for residents in inland areas like Ramona and Borrego Springs, where temperatures will soar above 100°F (37.8°C). Coastal areas will experience dangerous rip currents and high surf, with waves reaching 5 to 7 feet and occasional sets up to 11 feet. These conditions are especially hazardous for swimmers and surfers, as evidenced by recent fatalities and hundreds of rescues. Vulnerable populations, including the elderly and those with pre-existing health conditions, are at heightened risk of heat-related illnesses. Beachgoers are also at risk of drowning or injury due to strong currents and large waves.
