After more than a month of plateaus and slight increases, Southern California gas prices moved solidly downward in the last week, according to the Automobile Club of Southern California's Weekend Gas Watch.
The state average is $3.623 a gallon for regular as of Thursday -- 4.1 cents lower than last week.
The average price of self-serve regular gasoline in San Diego is $3.647, which is 4.3 cents below last week, 1.6 cents higher than last month, and 4 cents lower than last year.
In the Los Angeles-Long Beach area, the average price is $3.657 per gallon, which is 3.8 cents less than last week, 1.2 cents higher than last month, and 5.4 cents lower than last year. On the Central Coast, the average price is $3.679, down 3.5 cents from last week, 1.5 cents higher than a month ago, and 3 cents less than last year. In the Inland Empire, the average per-gallon price is $3.644, down 3.5 cents from last week, 3.5 cents higher than last month, and 3 cents less than last year.
"Los Angeles wholesale prices have now dipped below even the lowest levels of 2013, so if this trend holds, we should continue to see more gas stations selling regular unleaded for less than $3.50 a gallon," said Auto Club spokesman Jeffrey Spring.
