LAKE COUNTY, Calif. — Thanks to dropping gas prices, drivers in Northern California have something to be extra cheerful about this holiday season.

The average price of gasoline in the Golden State has continued to drop for a sixth straight week, according to AAA.

The average price for self-serve regular gasoline in California is $4.31, which is three cents lower than a week ago and 28 cents lower than a year ago, AAA reported.

But AAA said that trend may not stick around for long, as fuel prices are starting to rise nationally.

The average national price per gallon this week is $3.04, two cents higher than a week ago.

“Lower gas prices are great news for those planning year-end holiday travel,” said AAA Northern California spokesperson Doug Johnson. “With nearly 90 percent of travelers driving to their holiday destinations, that’s a lot of fuel — and a lot of savings.”

Here’s what the average price of self-serve regular gasoline is in each city:

San Francisco: $4.46.
Oakland: $4.30.
San Jose: $4.26.
Sacramento: $4.21.
Fresno: $4.21.
Stockton: $4.09.

AAA’s records show Lake County’s prices are falling about the middle range of prices in the state, coming in around $4.385 to $4.266 per gallon.

Meanwhile, the national average per kilowatt hour of electricity at a public EV charging station remained at 34 cents. In California, that average cost is 37 cents, AAA reported.
