The National Weather Service in San Diego forecasts a typical mild Fourth of July, with temperatures close to seasonal averages. In a report released earlier, the NWS San Diego cautions of a moderate Heat Risk by next Wednesday and Thursday, emphasizing that "all persons are vulnerable to heat and should take precautionary actions to protect yourself from the heat," particularly within the Inland Empire and San Diego County Valleys. This comes with an elevated risk of rip currents and possibly higher surf for this beach holiday weekend.
Planning to enjoy the fireworks outdoors? It might be best to hit the beach early. The NWS San Diego states that low clouds are expected to clear the beaches by mid-afternoon but will roll back slightly later in the evening, potentially reducing visibility to 3-5 miles in elevated valley terrain. These same low clouds are expected to sneak into western valleys and coastal areas during night and morning hours throughout the weekend.
As the week progresses, the NWS forecast discussion indicates a steady warming trend, with a high-pressure ridge possibly triggering a heat wave in the region. In addition to a hot holiday weekend, inland temperatures might exceed 100°F by Wednesday, with coastal areas not far behind, potentially hitting 80°F. Still, the uptick in monsoon moisture could provide a slight respite from the heat, albeit conditions are expected to remain dry.
For beachgoers, a Beach Hazards Statement is in effect through Saturday evening for Orange County and San Diego coastal areas. A southerly swell is anticipated to bring surf heights between 3-6 feet with sets up to 7 feet, particularly on south-facing beaches. The NWS advises swimmers and surfers to be careful due to strong rip currents and advises the public that the swell and surf will likely begin to subside by Sunday.
No significant disruptions are anticipated for aviation and maritime conditions. Coastal mariners should be free of any hazardous weather conditions through the middle of next week, and most of the desert and mountain areas will see mostly clear skies and unrestricted visibility.
While no Skywarn activation has been requested, both reports from NWS San Diego urge weather spotters to report significant conditions, assuring a collective effort to keep the public informed and safe as they celebrate this Independence Day weekend.
