San Diegans can expect a dynamic weather pattern through early next week, with temperatures oscillating before taking a substantial climb. According to the National Weather Service San Diego, today will be significantly warmer across the coast, valleys, and high desert areas than earlier this week, with coastal temperatures ranging from the mid-60s to the mid-70s. Inland areas like Orange County and the western valleys are forecasted to hit the mid to upper 70s, while the inland valleys anticipate highs in a similar bracket.
However, the weather narrative is set to change as we march swiftly forward into Thursday. Onshore flow will introduce cooler temperatures, particularly for coastal and inland areas. A slight uptick in heat is expected for the lower deserts, which could range from 79 to 82 degrees. Yet the mountains and the high desert should hold back only slightly on the thermometer, indicated by the Area Forecast Discussion by the National Weather Service San Diego.
Friday's forecast outlines a small uptick in warmth across most regions, with the mountains and inland valleys experiencing the greatest temperature increase – a trend indicating a rise of 4 to 8 degrees compared to Thursday. Going into the weekend, coastal areas will get some reprieve with temperatures dropping to the lower to mid-60s, while the valleys will hover in the 70s. The deserts can anticipate continued warmth, remaining in the mid to upper 80s.
Looking ahead to the start of next week, stronger high pressure aloft near the West Coast is predicted to drive temperatures significantly upward. The forecast for Monday and Tuesday signals an extreme hike up to 10 to 15 degrees above average for inland regions, with valleys potentially reaching the mid-80s to around 90 degrees, and lower deserts could surge into the mid to upper 90s. This considerable warming trend is yet another reminder of the fluctuating personality of Southern California's climate—marked by soaring highs amidst a season where cooler temperatures would normally be expected.
