In San Francisco, gas prices increased by 53 cents from an average of $3.73 a gallon a month ago.

In Oakland, gas prices increased by 53 cents from an average of $3.65 a gallon a month ago.

Patrick DeHaan, an industry analyst at GasBuddy.com says relief is coming.

"As most cities in California have seen or are very close to a peak, gas prices could fall over 50c/gal by early/mid November now as refinery issues are abating. Don't be in a rush to fill your tank. I expect every city to drop back UNDER $4/gal in a few weeks," tweeted DeHaan.
