Those in San Diego can expect to break out their summer attire a bit early this week as temperate climes take a backseat to a warming trend. Those looking for cool relief might want to find shade or a nice, air-conditioned room, as "high temperatures peak Tuesday with temperatures 10 to 20 degrees above seasonal average," according to the latest update from the National Weather Service San Diego.
In the broader context, this isn't just a one-time spike in the thermometer. The mercury is set to quickly rise and sustain its perch above normal through the week, particularly in inland valleys. Such trends to turn even warmer are linked to "periods of weak to locally moderate Santa Ana winds," according to the Area Forecast Discussion by the National Weather Service in San Diego. Inland coastal areas, valleys, and the low deserts should all prepare to feel the heat with widespread highs in the low to mid-80s forecasted.
Though a few patches of fog might tease the coast, chances of it forming along the water's edge are diminishing, lending the week an overall clear and dry aesthetic. Local aviators looking skyward will be pleased to find that VFR conditions are expected to prevail, with coastal fog development over nautical realms rated at a low likelihood of 10-20% for obstructing visibility.
For those with an affinity for the sea, marine conditions will also reflect the weather's unseasonably warm disposition. However, a slight chance of dense fog could obscure sight to less than 1 nautical mile through the morning hours. Beachgoers, meanwhile, should be cognizant of the tides; "high tide is predicted to fall below 6 ft by Monday," hinting at mildly safer shores for waterfront frolics and activities, as the potential for tidal overflow in normally dry areas becomes less of a concern, as per the NWS San Diego.
In the wrap-up for the week, looking forward, there's an expected slight dip in temperatures come Wednesday and Thursday, even as they remain considerably above average. By the weekend, the heat incrementally eases off, yet remains stubbornly above the seasonal norm. Those inland can anticipate numbers "10-15 degrees above normal," keeping the notion of a winter cool-down purely theoretical in this stretch of Southern California, according to the NWS San Diego.
