LOS ANGELES, Calif. — A brief but intense “mini heat wave” swept across Southern California over the weekend, setting record temperatures in several areas and prompting over two dozen heat-related rescues, mainly involving hikers caught off guard by the unseasonal heat.
The highest impact was felt on Saturday, when temperatures soared into the upper 90s and low 100s, creating dangerous conditions for those engaging in outdoor activities.
Record Heat Triggers Emergency Response
According to a report by the Los Angeles Times, 15 rescues were conducted in Orange County and nine in Riverside County on Saturday alone. Most of the incidents involved hikers experiencing heat exhaustion or dehydration along popular Southern California trails.
“Over a dozen people have been rescued collectively,” the Orange County Fire Authority (OCFA) reported in a Facebook post.
“According to the National Weather Service, it’s currently 96°F in Aliso Viejo.”
Among the most serious cases was a 55-year-old man who suffered heat exhaustion while hiking near the Hollywood Sign. The Los Angeles Fire Department (LAFD) responded with an airlift rescue to transport him to a hospital for emergency care.
Where the Heat Hit Hardest
Saturday’s temperature spikes were significant, with multiple locations setting or nearing daily records:
- Riverside: 104°F
- Woodland Hills: 103°F
- Anaheim: 98°F
- Aliso Viejo: 96°F
These unusually high temperatures for early May prompted public health and safety officials to issue advisories urging caution, especially for those heading outdoors.
“Unless you’re an experienced hiker or rider in this terrain and weather, we recommend waiting until it cools down,” the OCFA cautioned.
“If you do head out, please bring plenty of hydration with you.”
Social Media Highlights Dangerous Conditions
The OCFA also shared video footage of one of the rescues, showing firefighters assisting a hiker off a trail in sweltering conditions. The footage served as a reminder of how quickly a recreational outing can become a medical emergency in extreme heat.
Social media posts across the region highlighted scenes of fire crews carrying water, guiding lost hikers, and working with rescue helicopters in rough terrain.
Forecast: Relief on the Way
The good news for residents is that the heat wave began to taper off by Sunday. Although temperatures remained above seasonal averages, no new records were broken.
“We’re already seeing temperatures drop slightly across the region,” said KTLA meteorologist Kaj Goldberg in his Mother’s Day forecast.
“The hottest part of this short heat wave is behind us, and we’ll see a cooling trend begin this week.”
Still, public officials urged vigilance, noting that even moderate heat can be dangerous when combined with strenuous outdoor activity, especially for those unaccustomed to such temperatures.
Safety Reminders from Authorities
Agencies across Southern California issued reminders for staying safe during future heat waves or warm weekends:
🔥 Heat Safety Tips for Outdoor Activities:
- Hydrate often, even if you don’t feel thirsty
- Avoid peak sun hours (10 a.m. to 4 p.m.) for strenuous exercise
- Wear light, breathable clothing and a hat
- Bring more water than you think you’ll need
- Use sunscreen and reapply every two hours
- Tell someone where you’re going and when you expect to return

California’s Heat Trend: A Familiar Warning
This heat wave comes amid increasing concern over the frequency and severity of heat-related emergencies in California. Studies show that climate change is contributing to longer and more intense heat events, even outside traditional summer months.
“This wasn’t a typical summer heat wave, but it still had real consequences,” said one fire official.
“People need to remember that heat emergencies can happen anytime temperatures spike suddenly.”
With wildfire season approaching and drought conditions still persisting in parts of the state, emergency preparedness will remain a key focus for local agencies.
Looking Ahead
The cooling trend expected throughout this week will offer temporary relief, but forecasters caution that more warm spells are likely as the region heads into late spring and summer. Emergency services are urging the public to stay aware and prepare for more extreme weather ahead.
