Drivers may have hit the highways for the holiday weekend, but average gasoline prices in Modesto were unchanged in the last week, averaging $4.71/gallon on May 27, according to GasBuddy’s survey of 201 stations in Modesto.

The national average price of gasoline is unchanged in the last week, averaging $3.13/gallon. The national average is up 3.1 cents per gallon from a month ago and stands 43.0 cents per gallon lower than a year ago, according to GasBuddy data compiled from more than 11 million weekly price reports covering over 150,000 gas stations across the country.

“While the national average didn’t fall quite as far as anticipated for Memorial Day, it was still one of the most affordable since 2021 – and, when adjusted for inflation, among the cheapest in nearly a decade,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “As we move into the heart of summer, I believe we’re likely to see a relatively stable stretch for gas prices as refinery maintenance wraps up. Don’t expect the national average to rise above $3.30 per gallon, nor drop much below $3 for now. While refining issues on the West Coast are beginning to ease, several factors could still influence prices in the weeks ahead – including growing uncertainty around the upcoming hurricane season.”

Neighboring areas and their current gas prices were all unchanged from the week prior, with Stockton at $4.73 per gallon, Oakland at $4.94 and San Jose at $4.95 per gallon.

Historical gasoline prices in Modesto and the national average going back 10 years show the highest Modesto average was $5.95 on May 27, 2022 and the highest U.S. average was on that same date in 2022, at $4.60 per gallon.
