San Diego County is experiencing a significant increase in temperatures, with daily highs expected to soar 12 to 17 degrees above the seasonal averages until Tuesday, according to the National Weather Service (NWS). This warmth will precede a cooling trend that is predicted to bring rain to the region later in the week.
The current weather pattern will see areas of minor to moderate heat risk, particularly in the western valleys. Coastal areas are forecasted to reach temperatures between 73 and 82 degrees, while inland valleys could see highs from 83 to 90 degrees. Specific predictions for Sunday include highs of 87 degrees in Escondido and 90 degrees in Ramona, with coastal cities like San Diego and Oceanside hitting 77 degrees.
In addition to the heat, the NWS has warned of potential dense fog over higher coastal terrains Saturday and Sunday night into Monday morning. As relative humidity stays low, elevated fire weather conditions are expected, particularly for the foothills and eastern valleys in San Diego and Riverside Counties. Winds from the east and northeast may gust up to 40 mph in mountain passes, contributing to fire risks.
As the week progresses, temperatures are predicted to decrease significantly starting Wednesday, with a chance of rain expected to arrive Thursday and persist through Saturday. This marks a welcome change as residents anticipate relief from the recent heatwave.
By Thursday, the forecast indicates a drop in temperatures, with San Diego expected to reach a high of 68 degrees and coastal areas like Oceanside around 66 degrees. By next weekend, the chances of widespread rain are expected to increase, offering a refreshing contrast to the preceding warm and dry conditions.
With the changing weather patterns, it’s a positive indication that San Diego County will soon experience a shift towards cooler temperatures and much-needed precipitation, benefiting both the environment and residents.
