Gas prices have dropped for over 30 days. Where is gas the cheapest – and most expensive?

U.S. gasoline prices have dropped for over 30 consecutive days as of Friday, helping out drivers at the pump after prices reached averages of more than $5 per gallon last month.

The average cost of a gallon of regular gasoline in the U.S. hit $4.577 on Friday, according to AAA, with mid-grade costing $5.025, premium costing $5.320 and diesel at $5.572. Although current gas prices have dropped from last month, they are still up from the national average a year ago – $3.155.

But this week hasn’t brought entirely good news for U.S. consumers. Inflation jumped again in June, hitting another 40-year high. Prices increased 9.1% from a year earlier.

Patrick De Haan, head of petroleum analysis at GasBuddy, told USA TODAY that he predicts gas prices could continue declining in the coming weeks, though factors around the world could drive prices up again.

“I foresee the next few weeks us going down, barring an unexpected development or even something like unexpectedly good economic data,” he said. “If we do tip into a recession, that could push prices down. If there is data that we aren’t going to tip into a recession, that could cause prices to go up.”

“But really, I’m worried about the unforeseeable events like refinery shutdowns due to a hurricane or other factors,” he added.
