HONOLULU -- Hawaii on Monday reached the dubious milestone of being the first state in recent years to reach the $4 average for a gallon of regular unleaded gasoline. According to AAA's Daily Fuel Gauge Report, the Aloha State's $4 a gallon is the highest in the nation and a few cents higher than California's average of $3.959. Alaska was third at $3.902.

Some cities have already hit the $4 mark, including San Francisco, but Hawaii is the first state to reach the mark since 2008.

The national average is $3.558 a gallon, up a nickel from a week ago and 43 cents higher than a month ago.

Wyoming had the cheapest gas in the nation at $3.268.
