The forecast in San Diego promises steady warmth along the coast today, with minimal change from Monday and a slight temperature increase by about 5 degrees in the lower desert regions, reports National Weather Service San Diego. Coastal areas are expected to top temperatures ranging from 72 to 82 degrees, while western valleys and inland Orange County could see 82 to 87 degrees highs. Looking inland, the valleys might warm up to 83 and 89 degrees, with mountain regions at 4000 to 7000 feet seeing a range of 68 to 77 degrees and the high desert areas getting into the comfortable bracket of 80 to 84 degrees.
The warming trend, largely maintained by a stubborn high-pressure system to the south, is set to persist into Wednesday, with inland highs forecasted to be “5 to 10 degrees above average for inland areas,” according to a National Weather Service Area Forecast Discussion. Areas such as the inland valleys and the lower deserts will drive thermometers into the mid-80s to lower 90s and the mid-to-upper 90s, respectively, while the coastal regions will hover slightly cooler, with temperatures envisioned between 73 and 81 degrees.
