Temperatures in the U.S. are heating up, but the national average price for regular gas keeps falling, dropping to $3.838 per gallon on Thursday, according to AAA. It is the second straight week that fuel costs have remained under $4 per gallon, and they have been under $3.92 per gallon for seven days. Gas prices have dropped over 45 cents per gallon in the last month.

Gas prices have varied considerably throughout 2026, with fuel costs setting both a five-year low and a four-year high in a matter of months. The national average price for a gallon of regular gas dropped to $2.79 on Jan. 12, 2026. This was the lowest national average gas price since 2021. Severe winter weather across the country began causing gas prices to rise slightly in late January, continuing to rise into the $2.90 range in February.
