California gas prices hit record highs on March 5, 2026, due to Middle East tensions, strikes, and supply disruptions.

Gas prices in California surged on March 5, 2026, with San Diego County reaching $4.894 per gallon—the highest since November 2023—following a 15-day streak of increases. The statewide average hit $4.81, driven by escalating Middle East tensions, U.S.-Israel strikes on Iran, and disruptions to oil routes like the Strait of Hormuz. Crude prices rose, fueling a national average of $3.251. Refinery closures, seasonal shifts to costly summer-blend fuel, and declining inventories are compounding supply pressures, raising concerns about further price spikes.
