The average price of a gallon of self-serve regular gasoline in San Diego County rose two-tenths of a cent Monday to $4.893, its highest amount since April 27, increasing for the 11th time in 12 days.

The average price has risen 7.6 cents over the past 12 days, including eight-tenths of a cent Sunday, according to figures from the AAA and the Oil Price Information Service. The run of increases follows a 23-day streak of decreases totaling 9.2 cents.

The increases are expected to continue because of refinery issues, according to Patrick De Haan, head of petroleum analysis at GasBuddy, which provides real-time gas price information from more than 150,000 stations.

The average price is the second-highest on Memorial Day, behind only the $6.075 average in 2022.

The national average price rose four-tenths of a cent to $3.582, one day after dropping one-tenth of a cent. It is 4.2 cents more than one week ago but 3.3 cents less than one month ago and $1.028 lower than one year ago.

The national average price has dropped $1.434 since rising to a record $5.016 on June 14. It is also the second-highest amount for a Memorial Day, behind only the $4.619 average in 2022.
