Seattle drivers are paying sharply more at the pump, with average gasoline prices jumping 28 cents per gallon in just the past week to reach $5.06, driven by ongoing disruptions to oil flows through the Strait of Hormuz and the seasonal transition to summer gasoline blends.
Average gasoline prices in Seattle have risen 28.3 cents per gallon in the last week, averaging $5.06 a gallon today, according to GasBuddy’s survey of 775 stations in Seattle. Prices in Seattle are 75.1 cents per gallon higher than a month ago and stand 83.5 cents per gallon higher than a year ago.
Across the country, the national average price of gasoline has risen 23.2 cents per gallon in the last week, averaging $3.68 a gallon today. The national average is up 80.0 cents per gallon from a month ago and stands 66.1 cents per gallon higher than a year ago, according to data compiled from more than 11 million weekly price reports covering over 150,000 gas stations. Diesel prices are also climbing, with the national average increasing 34.0 cents compared to a week ago and standing at $4.951 per gallon.
In Seattle, GasBuddy price reports showed the cheapest station was priced at $4.25 a gallon yesterday, while the most expensive was $6.09 a gallon, a difference of $1.84 per gallon. Statewide, the lowest price yesterday was $3.69 a gallon, and the highest was $6.09 a gallon, a difference of $2.40 per gallon.

Nearby areas also saw increases. Tacoma averaged $4.87 a gallon, up 32.7 cents per gallon from last week’s $4.54 a gallon. The statewide average in Washington was $4.86 a gallon, up 28.6 cents per gallon from last week’s $4.58 a gallon. Yakima averaged $4.51 a gallon, up 26.7 cents per gallon from last week’s $4.24 a gallon.
“Consumers continue to feel the sting of rising oil, gasoline, and diesel costs as geopolitical tensions in the Middle East remain elevated, pushing gasoline prices to their highest levels in years while diesel could soon approach the $5-per-gallon mark nationally,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Until we see a meaningful resumption of oil flows through the Strait of Hormuz, upward pressure on fuel prices is likely to persist. At the same time, seasonal forces are beginning to intensify as several regions complete the transition to summer gasoline, creating a double headwind that could continue driving pump prices higher in the weeks ahead.”
Historical data shows Seattle’s average price on March 16, 2025, was $4.22 a gallon, compared with a U.S. average of $3.02 a gallon. The current $5.06 average represents a significant jump even compared to recent years, with March 2024 seeing $4.46 per gallon and March 2022, during the Russia-Ukraine war spike, averaging $4.91 per gallon. The rapid escalation reflects how quickly the Iran conflict has disrupted global energy markets and pushed prices higher than most recent historical comparisons.
