San Diego, CA, October 4, 2026 — San Diego County is currently under an extreme heat warning that is expected to remain in effect until Thursday night.
Meteorologists attribute the significant rise in temperatures, which are well above seasonal averages, to a combination of high pressure and prevailing offshore winds. These atmospheric conditions are contributing to a period of intense heat across the region.
Inland areas of San Diego County are forecast to experience temperatures reaching triple digits. Meanwhile, coastal communities are not exempt from the heat, with forecasts indicating highs in the mid-90s, climbing to near 100 degrees. Residents are advised to take precautions against the extreme heat.
Beyond the direct impact on public health due to the high temperatures, these conditions are also contributing to an elevated fire weather risk. The combination of heat and dry conditions can create an environment where wildfires are more likely to ignite and spread rapidly.
