“The national average price of gasoline has seen its first weekly increase since May 11, snapping a streak of eight straight weekly declines, with prices climbing in nearly four out of five states,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “The turnaround comes as oil prices have surged following the collapse of the ceasefire between the U.S. and Iran and the start of new attacks, with oil jumping another 4% in Sunday evening trading, an ominous sign that could bring additional gas and diesel price increases in the week ahead.”
Historical gasoline prices in Modesto and the national average going back five years show the lowest price of $4.15 per gallon in Modesto was on July 13, 2021 while the lowest U.S. average price of $3.11 was on July 13, 2025.
