The average price is 12.3 cents more than one week ago, 55.1 cents higher than one month ago and 28.4 cents greater than one year ago.

The Orange County average price rose for the 24th consecutive day, increasing 2.5 cents to $4.269, the highest amount since Oct. 26 and second highest in the state.

The Orange County average price is 12.7 cents more than one week ago, 56.3 cents higher than one month ago and 28 cents greater than one year ago.

The Orange County average price has risen 55.1 cents during the streak, the longest since a 27-day streak from Feb. 5-March 2, 2012.

The increasing prices are the result of reduced supplies caused by low levels of production in Southern California stemming from refinery maintenance, according to Jeffrey Spring of the Automobile Club of Southern California.
