For Bay Area residents planning to travel by car this summer, gas prices in California are expected to stay below $4 and trend lower in most states nationwide.  

As of June 3, Bay Area gas prices were around or below $4 per gallon with prices in San Francisco the highest in the region, according to AAA.

Here’s a ranking of average gas prices in each county as of June 3.

1. San Francisco — $4.1812. San Mateo — $4.0313. Sonoma — $4.0194. Alameda — $4.0195. Napa — $4.0176. Contra Costa — $3.9937. Marin — $3.9878. Santa Clara — $3.9769. Solano — $3.913 A recent hike in California prices was due to lower production this spring at California refineries, which produce gas specific to the state’s requirements, according to Michael Blasky, spokesman for AAA in Northern California.

“The good news is we are seeing production at California refineries returning to normal levels. Without another incident at a refinery, or a major economic incident that causes the global price of oil to fall or rise dramatically, I would expect to see gasoline prices remain under $4 for summer,” Blasky said.
