Gas prices in Wisconsin are on the way up.

The average is $4.18 per gallon for regular unleaded according to AAA and GasBuddy data as of Thursday, April 30. The average price in Wisconsin climbed nearly 50 cents in one week, jumping from $3.68 to $3.69.  

The higher prices are due to a combination of spring demand, an outage at the Whiting, Indiana refinery and tension in the Middle East, specifically oil flow disruptions in the Strait of Hormuz.

U.S. gas prices jumped past an average of $4 a gallon for the first time since 2022 at the end of March, according to the Associated Press. Since the U.S. and Israel launched the war against Iran, the cost of crude oil — the main ingredient in gasoline — has spiked and swung rapidly.
