San Diego rolled in today under a blanket of coastal clouds and temps hovering near 70°F, with a comfortable high near 78°F on tap. That mild start will not last. From tomorrow through Thursday, an Extreme Heat Watch is in effect, cranking inland highs into the 90s and low 100s, while overnight temperatures stay warmer than usual. At the same time, a Beach Hazards Statement is in effect, warning of elevated tides and 3–5 foot surf through tomorrow evening that could trigger minor coastal flooding and strong rip currents.
What To Expect This Week
From tomorrow morning through Thursday evening, inland valleys are expected to climb from the mid-90s into the triple digits, with Wednesday likely the peak of the heat and unusually warm nights along the coast. Scattered afternoon thunderstorms are possible across the mountains and high desert today. Any storm could bring brief heavy rain, lightning and small hail, with a small chance that one drifts into the eastern valleys.
Along the coast, residents and visitors should prepare for high astronomical tides of 7-7.5 feet and a 3–5 foot south swell. That combo will increase the risk of rip currents and minor tidal flooding in low-lying areas, according to the NWS San Diego.
How To Stay Safe
Limit outdoor work and play during the hottest part of the day, drink plenty of water, and keep an eye on older adults and anyone without air conditioning. If you need a break from the heat, San Diego County lists free Cool Zone cooling center locations and heat safety resources. You can call 2-1-1 for help finding a nearby site or transportation.
At the beach, follow lifeguard instructions, skip the water in areas flagged for dangerous conditions, and stay clear of flooded boardwalks and low-lying parking lots when tides and surf peak.
