The average price at the pump has now increased for 32 straight days, reports NBC News. Including the most recent increase, the price of gas is up 43 cents during that time. That gives an average price of $3.73 per gallon — the highest in four months — and in places including California and Hawaii, gas is already more than $4 per gallon.
An analyst with Gasbuddy.com said gas prices are increasing earlier than normal.
“This is what we usually see in late winter, early spring, but prices have started to rally two months earlier than usual,” Patrick Dehan told NBC News.
Maintenance at refineries and one refinery closing, as well as increased demand and a switch to more expensive summer fuel are all causing the price to rise.
