California's risk isn't one disaster, it's a stack of them. Wildfire season, the constant earthquake risk, and the utilities cutting power on purpose for days at a time. Prepping in California means planning for a grid that goes dark when the wind picks up — not just when a storm rolls through.
Long fire seasons mean evacuation readiness and air quality matter as much as the flames — smoke can make staying put dangerous even miles from the fire.
No warning, and they break water mains and gas lines. Stored water and a way to shut off utilities are non-negotiable here.
Utilities cut power deliberately during high-wind/fire-risk days. These can last 1-5 days and aren't an emergency to the grid operator — so you're on your own for power.
Water restrictions and a stressed supply make personal water storage and filtration smart year-round, not just in a crisis.
Mediterranean overall — dry, hot summers and mild winters near the coast, but it swings hard inland and in the mountains. California gets some of the best solar potential in the country (roughly 5.5-6 peak sun hours), which makes solar backup genuinely viable here, not just a nice-to-have.
The PSPS program is the thing most people underestimate. When utilities pre-emptively cut power, it can be out for days with no 'restoration' coming because nothing's technically broken. A power station with solar input is the single highest-value prep in California — it rides out a shutoff and recharges off that strong sun. Size it for your fridge, medical devices, and phones at minimum.
Two angles here: a quake can snap water mains with zero warning, and drought keeps the supply tight. Store at least one gallon per person per day for two weeks, and keep a filter on hand in case you're drawing from a questionable source after a quake.
Backup power with solar input. The PSPS shutoffs are predictable, frequent, and last for days — and California's sun makes solar recharging actually work. It covers your fridge, devices, and medical needs through a shutoff.
At least one gallon per person per day for two weeks, since an earthquake can cut the mains instantly. Keep a filter too in case you're sourcing water after a quake. Use our water storage calculator to size it for your household.
Yes — and they call for different things. Earthquakes are about stored water and utility shutoffs; wildfires are about evacuation readiness and air quality. A 72-hour kit covers the evacuation side; water storage and backup power cover the shelter-in-place side.
