Florida’s gas prices are climbing. According to AAA,  the average gas price is currently at $2.908 per gallon, as of March 22, up 84 cents from the same time last year. It’s also the highest price Florida drivers have seen since May 2018.

Florida’s gas prices have increased by over 70 cents since the start of the year. AAA said in March alone, gas has increased 30 cents.

The organization said the upward trend stems from tightening global crude supplies and market optimism that widespread vaccinations will boost fuel demand.

A large factor was recent winter weather that tightened the supply of gas after power outages at a group of refineries in Texas.
