Industry analyst Trilby Lundberg of the Lundberg Survey says Sunday that the jump follows a rise in crude oil costs.
Lundberg says the price at the pump is 15 cents lower than it was a year ago.
The highest average price in the nation is $3.38 a gallon in the San Francisco Bay Area.
The lowest average is $2.03 in Baton Rouge, Louisiana.
