"Gas prices have been stuck in somewhat of a limbo and remain near 2021 highs long after Hurricane Ida has dissipated. The damage done to oil production has been left behind and so far has prevented prices from resuming their seasonal decline," said Patrick De Haan, head of petroleum analysis for GasBuddy. "Ida caused the loss of over 30 million barrels of oil production in the Gulf of Mexico, and with gasoline demand remaining relatively high for the season, oil inventories remain relatively tight, preventing any organized decline in gas prices for the time being. As a result, we may have to wait a couple more weeks until hurricane season slows for oil inventories to start to rise and gas prices to fall."

GasBuddy is the authoritative voice for gas prices and the only source for station-level data spanning nearly two decades. Unlike AAA's once daily survey covering credit card transactions at 100,000 stations and the Lundberg Survey, updated once every two weeks based on 7,000 gas stations, GasBuddy's survey updates 288 times every day from the most diverse list of sources covering nearly 150,000 stations nationwide, the most comprehensive and up-to-date in the country.
