After a relatively warm start to the 2024–25 winter heating season (November–March), colder-than-normal temperatures across much of the United States in January and February resulted in increased consumption of natural gas and more withdrawals from U.S. natural gas storage than normal. By the end of March, the least amount of natural gas was held in U.S. underground storage in the Lower 48 states since 2022, with inventories 4% lower than the previous five-year average for that time of year, according to our Weekly Natural Gas Storage Report.
