Extreme Heat, Fire Risk in Santa Barbara County Forecast Through the Week

Santa Barbara County residents are bracing for a stretch of dangerous weather this week, as the National Weather Service has issued an extreme heat warning and a red flag warning covering much of the region through Friday, with little relief expected even after the official warnings expire.

Daytime temperatures in the city of Santa Barbara are forecast to reach the low 90s from Tuesday through Friday, with Thursday expected to be the hottest day at around 94 degrees, according to the Noozhawk. Inland areas will fare far worse: the Santa Ynez Valley and Cuyama Valley are expected to top 100 degrees, while coastal communities such as Goleta and Carpinteria will see highs in the mid-to-upper 80s.

The extreme heat warning covers most of southwest California, including Santa Barbara, Ventura and Los Angeles counties. Ryan Kittell, a senior meteorologist with the National Weather Service, said the extreme temperatures should last through Friday — but warned residents not to expect a meaningful cooldown after that.

"Even after Friday, the relief is really minimal," Kittell told Noozhawk. "Saturday will still be really hot, and even through the foreseeable future we don't see any big cool down."

Elevated Fire Danger Across the South Coast

The NWS has also issued a red flag warning for high fire-risk weather covering the Santa Barbara South Coast, the Cuyama Valley and the interior mountains of the county through Friday.

Mike Gray, public information officer for the Santa Barbara County Fire Department, said the combination of hazards is raising alarms among fire officials.

"The combination of extreme heat, very deep mixing heights, dry fuels, low humidity and locally gusty winds can lead to rapid fire growth and extreme fire behavior, including the potential for large plume-dominated fires," Gray said.

Southern Santa Barbara County will also see strong winds beginning Monday afternoon and continuing until Saturday night, with the strongest gusts expected Tuesday evening and Saturday night. Officials predict sustained winds of 15 to 30 mph, with gusts of 30 to 45 mph, particularly near the Gaviota coast, Refugio and the San Marcos Pass corridor — terrain familiar to longtime locals as the county's most fire-prone wind funnels.

Officials are urging residents to prepare an evacuation plan with at least two escape routes, and to avoid hiking or using front-country trails during red flag conditions. Residents should also refrain from using machinery that could spark near dry vegetation. Any smoke, fire or suspicious activity should be reported immediately to 9-1-1, with an exact location if possible.

The county's ReadySBC emergency alert system is also warning of possible public safety power shutoffs throughout the week due to fire risk. Residents can check whether their area could be affected on county websites and track outages on Southern California Edison's online map.

Who Is Most at Risk

Dr. Daniel Shepherd, deputy health officer for the Santa Barbara County Public Health Department, said the department's priorities during a heat wave are ensuring medical facilities are prepared and keeping residents informed about how to stay safe.

Those most at risk include elderly residents, people with underlying medical conditions and those taking certain medications, Shepherd said. People working or exercising in the sun are also particularly vulnerable, and he recommended proper sun cover in addition to staying hydrated.

Shepherd noted that many Santa Barbara residents, accustomed to the region's typically mild coastal climate, may not take heat precautions seriously enough — including runners and hikers heading into the canyons.

"The main thing is not to underestimate it," Shepherd said.

He encouraged residents to have a heat plan in place ahead of time, particularly if they rely on medical equipment that could fail during a power outage, and to seek out cool public spaces such as libraries if their homes lack air conditioning.

Where to Cool Down

The city of Goleta will host a cooling center Tuesday through Friday, open from noon to 6 p.m. in the Council Chambers at Goleta City Hall, 130 Cremona Drive.

Goleta's splash pad at Jonny D. Wallis Neighborhood Park in Old Town will also remain open through Labor Day weekend, operating from 10 a.m. to 6 p.m. six days a week, with closures on Wednesdays for maintenance.

Residents can sign up for ReadySBC alerts to receive the latest updates on extreme weather and emergencies.

How This Heat Stacks Up

While Kittell noted it is difficult to rank the hottest years because different metrics can be used, some data points illustrate just how unusual this summer has been. Downtown Los Angeles has recorded 23 days over 90 degrees since July — approaching the record of 25 days set in 1925, a mark expected to fall this year.

For beach communities, the heat will still be noticeable. Kittell said coastal areas will likely hit the upper 80s, with some of the hottest spots reaching 90. The Lompoc and Santa Maria valleys are expected to reach the 80s and are under a heat advisory.

The hottest readings in the broader region will be in inland valley areas such as Van Nuys, Burbank and Pasadena, where triple-digit heat is likely.

With the warnings in effect through Friday — and minimal relief forecast beyond — officials are asking Santa Barbara County residents to treat this week as an extended emergency-weather event: stay hydrated, check on vulnerable neighbors, avoid outdoor exertion during peak afternoon heat, and keep phones charged and ready for ReadySBC alerts in case fire conditions escalate.
