Gas prices: Decreases at the pumps after Memorial Day Weekend
The national average price for a gallon of regular gas decreased over the last week, as Thursday’s fuel costs dropped to $3.166.
The expected Memorial Day weekend gas price surge never quite happened. National gas prices held steady around the country, with some places even reporting a drop in costs compared to earlier in the week. A week ago, the average price for regular gas in the country averaged $3.195 per gallon, according to AAA. By Sunday of Memorial Day weekend, that cost dropped to $3.18 per gallon. There was a significant drop in gas prices on Memorial Day weekend in 2024, when the national average price was $3.59 per gallon.
This year’s national average gas prices for Memorial Day weekend were the least expensive since 2021. And more importantly, while there has been some slight fluctuation in pricing, overall, fuel costs have held steady over the last 30 days. The average price for a gallon of regular gas a month ago was $3.16, essentially a negligible difference from today’s costs.
Gas prices have fluctuated a great deal in the last half a year, especially so in 2025. From December’s average prices being close to $3 per gallon to rising to nearly $3.30 per gallon in the winter, fuel costs have increased and decreased many times since the Christmas holiday. Several geopolitical factors, including oil supply and demand, changes of presidential administrations, tariffs, and wars, have contributed to the inconsistent costs associated with gas. That being said, typically, the main determinant for how much one spends on gas is based on the state in which he or she resides.
People living on the West Coast reside in states with the most expensive gas in the nation, whereas those living within the states located near the Gulf of America have the cheapest fuel costs.
