U.S. Gas Prices See Biggest October Year-Over-Year Drop Since 2009

It's true: gas prices have continued their decline.

The national average on October 21 was lower than the same day last year for the 76th day in a row. It currently sits at $3.36 per gallon, down about two cents from last week.

Gas Buddy Chief Oil Analyst Tom Kloza predicts that the 82-day drop streak will be broken by next weekend. Gas Buddy analysts also believe there is a great chance that, before year's end, U.S. gasoline prices will dip to levels not witnessed since February 2011, when the Arab Spring was in full swing.

This is the first time since 2009 when October prices have been lower than the previous year for the majority of the month. In 2009, 26 out of 31 days in October had prices lower than the same day in 2008.

Monday recorded the lowest year-to-date national average ($3.549 per gallon) since June 10, when the yearly average up to that point was also $3.549 per gallon. Monday also saw the lowest 30-day average since this past Valentine's Day, at $3.407 per gallon, and the lowest seven-day average ($3.371 per gallon) since February 1, when the previous seven days averaged $3.366 per gallon.

The change from the beginning of the year is the lowest since January 28, when the average was $3.337 per gallon.

As of October 21, four percent of the country was under $3.00 per gallon. A month ago, less than one percent of the country saw prices under that mark. Conversely, only 0.6 percent of the United States could find prices over $4 per gallon, a welcome sign for many.
