Average gasoline prices in Louisiana rose sharply over the past week, climbing 33.4 cents per gallon to reach $3.36 per gallon, according to the latest survey of 2,436 stations by GasBuddy.
The current statewide average is 95.2 cents higher than a month ago and 69.0 cents above the price recorded one year ago.
Nationally, gasoline prices also moved higher. The U.S. average increased 23.2 cents over the last week to $3.68 per gallon. That figure is up 80.0 cents compared with a month ago and 66.1 cents higher than the same period last year, based on GasBuddy data compiled from more than 11 million weekly price reports across more than 150,000 stations.
Diesel prices saw even steeper movement. The national average price for diesel rose 34.0 cents in the past week, reaching $4.951 per gallon.
Within Louisiana, station-level prices varied significantly. The lowest reported price Sunday was $2.89 per gallon, while the highest reached $4.39 per gallon, a spread of $1.50 per gallon across the state.
Several metro areas also posted notable weekly increases. Baton Rouge averaged $3.35 per gallon, up 32.0 cents from the prior week. Prices in Jackson rose 40.8 cents to $3.42 per gallon, while New Orleans climbed 36.2 cents to $3.36 per gallon.
Historical data shows how current prices compare with recent years. On the same date in 2025, gasoline averaged $2.67 per gallon in Louisiana, compared with the U.S. average of $3.02. Prices were $3.08 in 2024, $3.04 in 2023, $4.11 during the 2022 energy spike, and $2.61 in 2021.
Patrick De Haan, head of petroleum analysis at GasBuddy, said geopolitical developments and seasonal fuel changes are driving the latest increases.
“Consumers continue to feel the sting of rising oil, gasoline, and diesel costs as geopolitical tensions in the Middle East remain elevated, pushing gasoline prices to their highest levels in years while diesel could soon approach the $5-per-gallon mark nationally,” De Haan said. “Until we see a meaningful resumption of oil flows through the Strait of Hormuz, upward pressure on fuel prices is likely to persist. At the same time, seasonal forces are beginning to intensify as several regions complete the transition to summer gasoline, creating a double headwind that could continue driving pump prices higher in the weeks ahead.”
