If you filled your gas tank anywhere in Riverside County on Sunday, you already know that prices spiked, but how much?

The average retail gasoline prices in Riverside have risen 1 cent per gallon in the past week, averaging $3.18 per gallon on Sunday, according to GasBuddy’s daily survey of 481 gas outlets in Riverside.

This compares with the national average that has not moved  in the last week to $2.53 per gallon, according to gasoline price website GasBuddy.com.

Including the change in gas prices in Riverside during the past week, prices yesterday were 40.5 cents per gallon higher than the same day one year ago and are 15.1 cents per gallon higher than a month ago. The national average has increased 8.8 cents per gallon during the last month and stands 22.7 cents per gallon higher than this day one year ago.

According to GasBuddy historical data, gasoline prices on January 22 in Riverside have ranged widely over the last five years: $2.78 per gallon in 2017, $2.83 per gallon in 2016, $2.41 per gallon in 2015, $3.58 per gallon in 2014 and $3.70 per gallon in 2013.

Areas near Riverside and their current gas price climate:

  • San Bernardino- $3.17 per gallon, up 2.1 cents per gallon from last week’s $3.14 per gallon.
  • Orange County- $3.24 per gallon, up 2.9 cents per gallon from last week’s $3.21 per gallon.
  • Los Angeles- $3.27 per gallon, up 2.9 cents per gallon from last week’s $3.24 per gallon.

“After several weeks of rising gasoline prices, it appears that perhaps the tide has turned and the bigger increases have started to fade,” said Patrick DeHaan, head of petroleum analysis for GasBuddy, in a prepared statement. “Oil prices remain near multi-year highs but do show some signs of buckling at least slightly, but for motorists, we have not and may not see sizable relief just yet.”

Great Lakes refinery issues continue to flare up with no warning, and gas prices there may continue to be more volatile in coming weeks, DeHaan added.

“Meanwhile, total U.S. oil inventories stand 127 million barrels lower than a year ago, which has led gas prices to these seasonally high levels. What continues to impress is the large spread in prices between stations nearby, even as gas prices remain somewhat low, unsuspecting motorists have seen price differences of 10 to as much as 50 cents per gallon between neighboring stations in some large cities.”
