MADISON (WKOW) -- When you head to the pump this summer, you might get hit with a little bit of sticker shock.
This summer could be the most expensive in four years.
Wisconsin's average gas price is up more than 30 cents from this time last year. Compared to the national average, Wisconsin is still a little cheaper. Wisconsin is $2.68 per gallon, nationally it's $2.81.
These are the highest gas prices we've seen since 2014.
The U.S. Energy Information Administration says rising oil prices are part of the problem and that translates into higher gas prices.
AAA also says as we head into the summer months we're also starting to see an increased demand.
"As the economy continues to improve more and more people are hitting the road," AAA Public Affairs Director, Nick Jarmusz. "Both for their daily commutes as well as taking advantage of leisure time and vacations to hit the road."
AAA couldn't tell us when it expects to see prices start to go down, but in the meantime, it suggests shopping around to find the best price.
"You can save money by stopping to get gas when you see the best prices, instead of waiting until you're on empty."
AAA also has an app that helps people search gas prices by location in real time -- it's called the TripTik mobile app. You don't have to be a AAA member to download the app and use it.
