The cheapest gas in Seattle clocks in at nearly $5 a gallon this week, with no relief in sight.
Average gasoline prices in Seattle have risen 3.9 cents per gallon in the last week, averaging $5.36 a gallon today, according to GasBuddy's survey of 775 stations in Seattle. Prices in Seattle are 4.7 cents per gallon higher than a month ago and stand 84.1 cents per gallon higher than a year ago.
GasBuddy price reports show the cheapest station in Seattle was priced at $4.75 a gallon Sunday, while the most expensive was $6.19 a gallon, a difference of $1.44 a gallon.
Across Washington state, the lowest price Sunday was $4.19 a gallon, and the highest was $6.19 a gallon, a difference of $2.00 a gallon.

The national average is down 5.0 cents per gallon from a month ago and stands 92.6 cents per gallon higher than a year ago, according to GasBuddy data compiled from more than 11 million weekly price reports covering over 150,000 gas stations across the country.
The national average price of diesel has increased 16.6 cents compared to a week ago and stands at $5.584 per gallon.
In nearby areas, Tacoma’s average price is $5.16 a gallon, up 8.1 cents per gallon from last week’s $5.08. The statewide average in Washington is $5.19 a gallon, up 6.9 cents per gallon from last week’s $5.13. Yakima’s average is $5.05 a gallon, up 15.8 cents per gallon from last week’s $4.89.
“Average gasoline prices moved higher in the majority of states over the last week, with fewer than 10 states seeing declines, while diesel surged nearly 17 cents per gallon nationally, leaving it less than 25 cents away from an all-time record high,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Gasoline, while not at all-time records, is at its highest level ever recorded this late in the calendar year, meaning Americans could for the first time ever see a national average price of gasoline above $4 per gallon on Labor Day — eclipsing the previous record of $3.83 per gallon set in 2012."
De Haan noted that while some oil shipments are apparently getting through the Strait of Hormuz, the dominant force propping up both gasoline and diesel prices is increasingly the growing loss of Russian refinery capacity due to the ongoing war with Ukraine.
GasBuddy’s historical data shows Seattle’s average price on Aug. 24 was $4.52 a gallon in 2025, $4.38 in 2024, $5.19 in 2023, $4.94 in 2022 and $4.02 in 2021. The U.S. average on those dates was $3.12 in 2025, $3.33 in 2024, $3.80 in 2023, $3.86 in 2022 and $3.14 in 2021.
