Average retail gasoline prices in Savannah have risen 4.5 cents a gallon in the past week to $3.27 a gallon on Sunday, according to GasBuddy's daily survey of 262 gas outlets in Savannah.
The national average has not moved in the last week and sits at $3.24 a gallon, according to gasoline price website GasBuddy.com.
Prices Sunday were 14.3 cents a gallon higher than the same day one year ago and are 0.6 cents a gallon lower than a month ago.
The national average has decreased 19.1 cents a gallon during the last month and stands 1.3 cents higher than a year ago.
"With just hours to go before Christmas, it appears that the national average may set a new all-time record high, barely edging out 2011 as the most expensive average for gasoline on Christmas Day," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. "The bad news likely won't stop there. Gasoline prices in six out of the last seven years have increased between Christmas Day and January 15 of the following year. If the national average rises to at least $3.26 a gallon before New Year's Day it will mark the highest start for gas prices ever on the first day of the year."
