California gas prices have jumped to shocking levels in March 2026. One Los Angeles station charged nearly $9 per gallon. The California gas prices average now stands at $5.84, far above the U.S. average of $3.98. This surge links directly to the Iran-U.S. war and oil supply disruptions. The Strait of Hormuz blockage has tightened global crude supply fast. Fuel demand remains steady, but supply is under pressure. This gap is driving California gas prices higher each week. Experts say volatility may continue. Small relief signs have emerged after limited tanker movement resumed. Still, drivers face rising costs daily across California.
