Trails across Southern California are becoming increasingly hazardous as an unseasonably early heatwave prompts rattlesnakes to emerge weeks ahead of their typical schedule. Wildlife officials are issuing warnings following a spate of snake bites, including two fatal incidents.

In Ventura County, authorities have reported several rattlesnake bite incidents in recent weeks, with one proving to be fatal. A 46-year-old woman from Moorpark lost her life after being bitten while hiking in Wildwood Regional Park. Although snake bites are not uncommon in the area, fatalities are considered unusual, emphasized local officials.

Just days before this incident, a teenage girl was bitten while riding her bicycle near the Wendy Drive trailhead in Newbury Park. Firefighters had to hike up the trail to reach her, and she was subsequently hospitalized. Fortunately, she sustained only minor injuries and was in stable condition.

This premature snake activity in Southern California echoes a similar unfortunate event in Orange County. In early February, a 25-year-old man was bitten while mountain biking near Irvine. Tragically, his condition worsened and he passed away in March.

Experts attribute this early snake activity to unusually warm temperatures, which are disrupting the rattlesnakes’ typical dormancy period, causing them to emerge sooner than expected.

Officials and wildlife experts say warmer‑than‑normal temperatures are driving rattlesnakes out of their hibernation-like state of dormancy sooner than usual.

The situation is so bad, it’s prompted the U.S. Forest Service to issue an alert reminding outdoor lovers that “as temperatures rise, rattlesnakes become more active in the forest.” San Bernardino National Forest rangers are urging hikers to watch their step and keep pets close. 

Rattlesnakes are shy by nature and usually avoid humans, but they will strike when surprised or threatened.

They can strike at a distance of more than five feet, and several species native to the region, including the Western Diamondback and Southern Pacific rattlesnakes, are known for their potent venom. 

Experts say the early surge in sightings and bites is tied to a combination of dry conditions and unusually warm weather that has brought people outdoors earlier this spring.

Officials advised that hikers stay on clear paths, avoid tall grass and brush, and give any snake plenty of space.

They also repeated standard venom‑bite guidance: call 911 immediately, keep the bite victim still, keep the injured limb lower than heart level, and avoid tourniquets, cutting the wound, ice or sucking out venom. 

The recent spike in rattlesnake encounters underlines how quickly the natural world responds to changes in weather.

With warm conditions expected to continue, authorities are urging anyone planning outdoor activities to be extra cautious and prepared, because in rattlesnake country, the danger is real and the season has hardly begun.
