After an all-too-brief drop this spring, gas prices are reversing course and resuming their summer march upward.
A gallon of regular unleaded in Tampa Bay now averages $3.64, up 4 cents from $3.60 a week ago and $3.49 a month ago. Statewide, a gallon averages $3.70, compared to $3.67 a week ago and $3.56 a month ago.
That rise mirrors a jump in crude oil prices recently as investors continue to bid up the price on speculation the U.S. economy will improve.
Also, a weaker U.S. dollar and an agreement to bail out the Greek government drove prices higher, according to Jessica Brady, spokeswoman for AAA Auto Club South.
"As hurricane season starts to heat up with various storms forming, it's likely oil prices will remain volatile on that factor alone," Brady said.
"We are definitely going to see ebbs and flows in the oil market for the remainder of the summer with gas prices in continual fluctuation."
