The chart of gas prices at The News Tribune’s Gas Deal Finder is beginning to look like an electrocardiogram with wide swings between highs and lows this summer.
Today’s average price for a gallon of unleaded regular in the Tacoma was $3.87 this morning, nearly 20 cents higher than it was just a week ago.
But that price is still 45 cents less than it was during the Memorial Day weekend.
Today’s price, however, is almost 40 cents more a gallon than it was a little more than a month ago.
Analysts are blaming a fire at Chevron’s San Francisco Bay area refinery for the spike in the last few days.
Nationwide, gas prices are moving upward but not as sharply as they are on the West Coast, a market that’s isolated by geography from the rest of the nation’s gasoline market.
The national average was $3.676 a gallon today compared with $3.427 a month ago.
The lowest price in the Tacoma area today was at a 7-Eleven at 19825 Mountain Highway where unleaded regular was selling form $3.61 a gallon. A 7-Eleven at 3541 Martin Way E was the lowest price source of gas in the Olympia area. That store was selling gas for $3.54 a gallon.
