A rattlesnake found struggling in a Rancho Santa Fe swimming pool is drawing attention for what it may signal about snake activity across Southern California.
The snake, discovered in a residential pool in the San Diego County community, appeared to have been trapped for hours, circling the water and unable to escape. A professional handler with SoCal Rattlesnake Removal said the season is already “busier than prior years and started earlier” — a notable shift for a region where peak snake activity typically arrives later in spring.
This year’s March 2026 heat wave pushed Southern California temperatures 20 to 25 degrees above normal, with inland areas reaching the 90s to near 100°F — levels that are unusual for this time of year.
By comparison, typical March conditions are far cooler, generally in the upper 60s to low 70s, meaning this year’s spike represents a sharp early-season jump rather than normal spring warming.
Officials in Southern California have warned that the record-breaking March heat triggered an early surge with a growing number of snake reports across the region.
According to the Orange County Fire Authority, the warm weather is “marking the start of rattlesnake season” and bringing increased activity into public and residential spaces.

In Orange County, Mission Viejo Animal Services Center responded to multiple calls in a single day — including a rattlesnake found under a backyard patio chair and another stretched across a residential sidewalk near a park. A spokesperson said recent conditions “brought the rattlesnakes out earlier than last year.”
Landscapers working in those same areas report the shift is noticeable on the ground. Crews with BrightView Landscape Services described frequent encounters in park-adjacent neighborhoods. “Sometimes we see two or three a day,” one worker said.
Farther south, the trend is even more quantifiable. In San Diego County, snake wranglers with San Diego Rattlesnake Removal reported more than 40 calls in February, compared to just 18 during the same period last year — a sharp increase before the season has fully developed.
Public sightings are rising alongside those calls. At Mission Trails Regional Park, in central San Diego County, rattlesnake reports have effectively doubled as temperatures climb, with experts noting that warmer conditions are bringing snakes out earlier and increasing movement across trails and open spaces.
Wildlife officials say warmer weather accelerates emergence, while rain-driven vegetation supports more prey — drawing snakes into the same environments people occupy, including backyards.
“San Diego’s original residents are beginning to stir,” one regional report noted, as snakes emerge across coastal and inland habitats alike.
The reports point to a consistent trend — snakes are active earlier, moving more, and showing up in places where human activity overlaps with habitat.
Southern California pool professionals should watch out. The Rancho Santa Fe incident may be the only recent case to make headlines, but the conditions behind it — increased movement, earlier emergence, and more frequent backyard encounters — are already in place.
And that means the window for encountering snakes on a routine service stop may be opening sooner than expected.
