Washington State Gas: Current Prices And Trends
Washington State Gas: Current Prices and Trends
Gas in Washington costs about $5.76 per gallon on average for regular unleaded as of May 7, 2026, according to AAA, while the national average is $4.56 per gallon. In the Seattle-Bellevue-Everett area, the average is even higher at $5.96 per gallon, which helps explain why Washington drivers are paying some of the highest fuel costs in the country.
What drivers are paying
The state average is not the same everywhere in Washington, and metro prices can swing by 50 cents or more depending on where you fill up. AAA's latest data shows regular gas at $5.96 in Seattle-Bellevue-Everett, $5.88 in Tacoma, $5.80 in Olympia, $5.73 in Vancouver, $5.70 in Bellingham, and $5.37 in Spokane.
| Washington area | Regular | Mid-grade | Premium | Diesel |
|---|---|---|---|---|
| State average | $5.763 | $6.002 | $6.260 | $6.845 |
| Seattle-Bellevue-Everett | $5.957 | $6.159 | $6.413 | $7.025 |
| Tacoma | $5.881 | $6.084 | $6.333 | $6.972 |
| Spokane | $5.368 | $5.605 | $5.873 | $6.562 |
Why prices are high
Washington's fuel taxes are a major reason gas is expensive, but they are not the only reason. A June 2025 state increase lifted the gasoline tax from 49.4 cents to 55.4 cents per gallon, and another inflation-linked annual increase begins July 1, 2026; diesel taxes rose too, according to reporting on the new law.
Geography also matters because the Pacific Northwest has fewer refineries than many other regions, so Washington fuel often depends on complex supply chains and long-distance transportation. That combination of taxes, logistics, and regional supply makes Washington structurally more expensive than the U.S. average even when crude oil prices are stable.
"Washington always has among the nation's highest gas prices, a function of tax policy and geography."
Recent trend
The price trend has been moving up in 2026. AAA shows Washington's regular gas average at $5.392 a month ago, $5.570 a week ago, and $5.763 today, which means drivers have seen a steady increase rather than a brief spike.
Longer-term EIA data shows the state's monthly gasoline price at 4.870 dollars per gallon in March 2026, up from 4.041 in February and 3.774 in January, reinforcing the pattern of rising prices this spring. Washington also posted 2025 monthly averages mostly above $4.00, with 2026 already moving well above that level.
How Washington compares
Washington is not just above average; it is far above the U.S. national benchmark. AAA's latest readout places Washington at $5.763 for regular fuel versus the national average of $4.558, a gap of about $1.21 per gallon.
That spread is why Washington regularly ranks near the top of state gasoline prices, alongside California and Hawaii. Recent reporting also noted that Washington was the second- or third-highest state at various points in spring 2026, depending on the exact day measured.

Best places to save
Within Washington, the cheapest big-city averages in AAA's latest data are in Spokane and the Tri-Cities region, while Seattle-area and Tacoma-area stations remain the most expensive among the major metros listed. Drivers who can time purchases around weekly swings may save a few cents per gallon, but the larger advantage usually comes from choosing a lower-cost metro or neighborhood.
- Check the local metro average before you buy, since city-to-city gaps are large.
- Compare stations on the same road corridor, because prices often cluster by neighborhood.
- Use regular unleaded if your vehicle does not require premium, since premium runs about 50 cents higher statewide.
- Watch for weekend and holiday spikes, when demand can temporarily push prices upward.
Current outlook
The near-term outlook is for continued volatility rather than a sharp drop. AAA's own national commentary has tied recent increases to oil-market pressure, and Washington's price structure means local drivers often feel those changes more strongly than the rest of the country.
For Washington motorists, that means the best answer to "how much is gas?" is: roughly $5.76 a gallon statewide right now, with many metro areas ranging from the mid-$5s to nearly $6.00 for regular unleaded. If you drive in Seattle, Tacoma, or Olympia, expect to pay closer to the top of that range; if you drive in Spokane, Yakima, or the Tri-Cities, you may find meaningfully lower prices.
