Missoula, MT (KGVO-AM News) - Average gas prices in Montana have now increased in 22 out of 27 weeks. After prices increased three weeks in a row, they finally dropped this week. Patrick De Haan is the head of petroleum analysis at GasBuddy, and he provided the current numbers.

“Average gasoline prices in Montana have fallen 2.1 cents per gallon in the last week, averaging $3.26 per gallon today,” De Haan said. “Prices in Montana are 7.5 cents per gallon higher than a month ago and stand 23.7 cents per gallon lower than a year ago.”

As of Monday morning, many stations in Missoula still had their prices set to around $3.27 per gallon.

According to GasBuddy price reports, the cheapest station in Montana was priced at $2.88 per gallon yesterday, while the most expensive was $4.09 per gallon.

Montana is currently ranked 12th in the U.S. when it comes to the average price of gas, which is one spot lower than last week.

“The national average price of gasoline has fallen 5.3 cents per gallon in the last week, averaging $3.09 per gallon today,” De Haan said. “The national average is down 1.1 cents per gallon from a month ago and stands 37.4 cents per gallon lower than a year ago. The national average price of diesel has decreased 3.2 cents in the last week and stands at $3.64 per gallon.”

According to De Haan, nearly every state saw average gas prices decline for the second straight week, even as the nation celebrated July 4 with the lowest national average for Independence Day since 2020.

"That downward momentum may continue, as OPEC’s weekend decision to boost production by a larger-than-expected 548,000 barrels per day in August adds further pressure to oil prices, potentially accelerating supply builds,” De Haan said. “If tensions in the Middle East remain contained and the Gulf is spared from major hurricanes, the odds are improving that the national average could dip below $3 per gallon later this summer, but in the meantime we could see the national average falling to its lowest summer level since the pandemic."
