San Diego County Braces for Above-Average Temperatures Amid Drought
San Diego County is preparing for a significant heatwave this week, with temperatures soaring 6 to 15 degrees above average due to a high pressure system replacing a weak storm that recently affected the region. The National Weather Service has predicted that daytime highs will reach 69°F on Monday, followed by even warmer temperatures reaching 75°F on Tuesday and 76°F on Wednesday and Thursday, before cooling slightly to 73°F on Friday.
In the city of Escondido, the heat will be even more intense, with high temperatures expected to hit 78°F on Monday, 86°F on Tuesday, and reaching up to 89°F on Wednesday and Thursday. By late in the week, some inland valley locations in the county may even experience temperatures exceeding 100°F. This surge in temperature comes amid ongoing concerns over drought, as below-normal seasonal rainfall raises the risk of fire hazards in the region.
Since the start of the rainy season on October 1, Escondido has received only 8.20 inches of precipitation, which is 5.99 inches below average for this time of year. This lack of rainfall contributes to heightened concerns from firefighters, who are closely monitoring the heat situation. The forecast for Tuesday indicates that it will be the coolest day of the week at the coast, with temperatures 5 to 10 degrees below average, while valleys and deserts may see highs that are 10 to 15 degrees below normal.
Wind Conditions and Advisories
A wind advisory is in effect for the county’s deserts and mountains from 5 a.m. Monday until at least 5 a.m. Wednesday. Peak wind gusts are anticipated to range from 45 to 55 mph in the desert-mountain slopes and surrounding areas. Additionally, marine conditions will see strengthening northwest winds on Monday and Tuesday, with sustained winds of 15 to 20 knots and gusts up to 25 knots expected across outer coastal waters.
On Monday, downtown San Diego is expected to enjoy mostly sunny weather with a high of around 68°F and light afternoon winds. The overnight low in San Diego is forecasted to drop to about 57°F. As the week progresses, marine forecasters warn of high risks for rip currents with surf heights reaching from 3 to 5 feet on Tuesday. A small craft advisory will also be in effect from 2 a.m. Monday until at least 11 p.m. Tuesday for waters extending from San Mateo Point to the Mexican Border, as conditions remain volatile.
Upcoming Weather Changes
Conditions will begin to change mid-week, as temperatures are expected to stabilize closer to seasonal averages. Inland valley highs may experience a dramatic drop of 20 to 25 degrees compared to the peak heat anticipated earlier in the week. Mountain areas will likely see a mix of partly cloudy skies and patchy fog until Tuesday, transitioning toward mostly sunny conditions by mid-week with highs in the mid-60s to low 70s.
The combination of elevated temperatures and lower rainfall levels has raised alarm for potential fire risks throughout the region, prompting both residents and local authorities to be vigilant as the forecast develops. With conditions shifting rapidly, residents are urged to prepare for fluctuations and take necessary precautions.
