BALTIMORE, MD—After falling last week, the nation’s average price of gasoline has returned to a rise, climbing 10.0 cents from a week ago to $3.34 per gallon this week according to GasBuddy data compiled from more than 12 million individual price reports covering over 150,000 gas stations across the country.

The national average is up 22.0 cents from a month ago but 3.2 cents per gallon lower than a year ago. The national average price of diesel has fallen 2.7 cents in the last week and stands at $4.03 per gallon—33 cents lower than one year ago.

“A majority of the nation’s 50 states have seen gasoline prices rise, with the national average posting a gain for the second straight week, a trend that is hardly surprising for this time of year, and will likely continue as the entire nation has now made the first step toward summer gasoline,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “The pinch at the pump has been manageable for now, with prices about 30 cents higher than mid-January, but that will likely change as we enter the madness we tend to see in March with refinery maintenance hitting its peak, impacting how much gasoline can be produced as we make the changeover to the summer blends. This always crimps supply, leading to further gas price increases.”

The most common U.S. gas price encountered by motorists stood at $3.29 per gallon, up 30 cents from last week, followed by $2.99, $3.49, $3.09, and $3.19 rounding out the top five most common prices. The median U.S. gas price is $3.22 per gallon, up 9 cents from last week and about 12 cents lower than the national average. The top 10% of stations in the country average $4.58 per gallon, while the bottom 10% average $2.77 per gallon. The states with the lowest average prices: Texas ($2.80), Oklahoma ($2.80), Mississippi ($2.82). The states with the highest average prices: California ($4.79), Hawaii ($4.66), and Washington ($4.08).
