AUGUSTA (AP) — The average retail cost of a gallon of gas in Maine has jumped another nickel.

Price-monitoring website GasBuddy.com reported Monday that gas in Maine is now up to an average of $3.54 per gallon.

That’s 14 cents above the national per-gallon average.

Maine prices are still almost 30 cents lower now than they were a year ago at this time, but more than 6 cents higher than a month ago.

A company analyst said prices are expected to continue to rise as refineries are in their maintenance season before switching over to more expensive summer gasoline.

The average is based on a survey of more than 1,200 Maine gas stations.
