The national average price for a gallon of regular gasoline is $3.67, up from $3.55 just one week ago, according to the AAA Daily Fuel Gauge Report. A month ago, the price of gas averaged $3.60 per gallon nationwide.

CNN Money spoke with Tom Kloza, the chief oil analyst at, about the recent upswing in gas prices. Kloza predicts that prices will continue to climb, and says there is a 50 percent chance that prices may surpass this year’s high of $3.79 per gallon, which was reached in February. One reason for the spike in prices is because we’re in the peak of the summer driving season, which has reduced the supply of gasoline. CNN Money also says that domestic oil refineries are operating at full capacity. If a refinery closes down for repair or is impacted by a hurricane or other summer storm, supplies may further tighten, which could also send the price up.

Luckily for drivers, prices may not climb that much higher. CNBC spoke with AAA representative Michael Green, who said that it is unlikely that most states will reach the $4 per gallon threshold. CNBC says there are a few tricks to save some money at the pump, including credit cards that offer money back on gasoline purchases, or using smartphone apps like GasBuddy or AAA TripTik, that show the best gas prices near you.
