Staying safe in California
California's landscapes bring hazards that can catch visitors off guard: cold Pacific surf and sneaker waves, wildfire smoke, desert heat, mountain altitude, and coastal road closures. Plan for the conditions in your particular region and follow current local warnings.
The ocean and the coast
The Pacific is cold and powerful year-round. Rip currents are a major beach hazard: stay calm, do not fight the current toward shore, and swim along the shoreline to escape its pull before angling back. If you cannot reach shore, relax and call or wave for help. Choose beaches with lifeguards on duty. On the rugged North Coast around Mendocino and at Big Sur, sneaker waves can surge far up the beach — never turn your back on the ocean and keep off wet, low rocks.
Tide pools, bluffs, and cliff edges are beautiful but unstable; stay on marked trails at reserves like Point Lobos and Torrey Pines, and check tide times before exploring coves and sea caves.
Wildfire, heat, and altitude
Wildfires can occur throughout the year, with dry, hot or windy periods bringing particular risk. Smoke can affect air quality far from the flames. Check AirNow and CAL FIRE, but follow local emergency alerts and evacuation orders without waiting for a website update; never drive around closures. In the Palm Springs desert, summer heat can be dangerous. Carry ample water and snacks, choose short early-morning outings in suitable conditions, and avoid strenuous activity during extreme heat. Check the forecast and know the signs of heat illness.
At Lake Tahoe and on the Palm Springs Aerial Tramway you gain altitude quickly; take it easy on arrival, hydrate, and be aware that Sierra weather can change fast even in summer.
Roads, earthquakes, and everyday precautions
State Route 1 through Big Sur and other coastal and mountain roads can close for wildfire, rockslides, storms or winter chain controls. Check Caltrans QuickMap before remote drives and download maps where coverage is poor. During an earthquake indoors, drop, cover and hold on; do not rush outside while the building shakes. If outdoors, move to an open area away from falling hazards. If driving, pull over carefully away from bridges, trees and power lines and stay in the vehicle until the shaking stops.
Take ordinary precautions against theft: keep valuables out of sight in parked cars at trailheads, beaches and city lots, and take essential belongings with you. In an emergency, call 911.
