When Is Gas Cheapest in California?
Gas prices in California follow seasonal patterns. Winter months typically offer the cheapest prices, while spring and summer bring higher costs.
Current Price Trends
As of February 2026, California's statewide average is $4.23 per gallon. This represents the lowest level since June 2021. However, prices are beginning to edge higher as February progresses because refineries are switching to summer-blend gasoline production.
Here's what's happening with California gas prices:
- Winter prices are dropping: Gas fell for two straight months at the start of 2026
- Spring transition pushes prices up: Refineries switch blends in late winter and early spring
- Summer prices peak: Summer-blend requirements and higher driving demand drive costs up
- Fall prices start falling again: Lower demand and winter-blend transition lower prices
Regional Price Variations
Prices vary significantly across California:
| Region | Current Price | Year-Over-Year Change |
|---|---|---|
| Los Angeles-Long Beach | $4.38 | Down 6 cents |
| San Diego | $4.42 | Down 9 cents |
| Central Coast | $4.35 | Down 8 cents |
| Riverside | $4.13 | Down 19 cents |
| Bakersfield | $4.30 | Up 2 cents |
Riverside offers the cheapest regular gas in Southern California at $4.13 per gallon. If you live in the 94103 zip code (San Francisco), you'll pay premium prices year-round compared to inland areas.
Future Price Outlook
California faces significant price pressures ahead. Two major oil refineries are scheduled to close: Phillips 66 in Los Angeles and Valero in Benicia. These closures will reduce the state's refining capacity by 21 percent over the next three years. This supply reduction could push prices substantially higher by late 2026.
Your Action Plan
Fill up your tank during winter months when prices are lowest. If you drive frequently, consider filling up in lower-cost regions like Riverside or Bakersfield when possible. Monitor gas prices weekly to catch dips before seasonal increases take hold. Track prices using AAA's gas price tool to find the cheapest stations in your area.
