The National Weather Service San Diego has issued a weekend weather forecast that warns of a continued moderate HeatRisk for inland valleys and mountains, with a Major HeatRisk for desert areas. Temperatures on Saturday should hover between 89 to 101 degrees for inland valleys, while the low desert faces blistering highs of 108 to 111 degrees. This warming trend is expected to persist, with minimal cooling on the horizon for most inland regions until later next week, according to the National Weather Service.
Sunday and Monday, coastal regions will enjoy slightly cooler temperatures, ranging from 73 to 81 degrees, while inland areas will not see much respite. The high desert is projected to have temperatures between 100 to 106 degrees. And for the low desert, the heat cranks up even more, with a high ranging from 111 to 114 degrees on Monday. The National Weather Service also notes a 10-15% chance of showers and thunderstorms in certain areas as moisture creeps in, potentially offering a paltry buffer against the scorching conditions.
As the heat languishes, residents are advised to take necessary precautions. Experts recommend staying hydrated, avoiding strenuous outdoor activities during peak heat hours, and checking on vulnerable populations. The National Weather Service's forecast discussion emphasizes that despite some cooling along the coast, "there remains enough coverage of moderate HeatRisk across the Inland Empire and mountains" and Major HeatRisk in the low deserts.
Marine conditions appear safe through Wednesday for those seeking to catch a wave or bask on the coastline. However, the influx of a long-period southwesterly swell beginning late Sunday is set to bring elevated surf and high rip current risks starting Monday. The National Weather Service advises that we could see wave heights of 3 to 6 feet, with higher sets on southwest-facing beaches, so beachgoers should exercise caution. Likewise, those with aerial concerns should note that haze and smoke from regional fires, particularly the Gifford Fire in Santa Barbara County, could compromise visibility at higher altitudes above 10,000 feet MSL.
