Washington State 2026 Gas Prices Shock Drivers Right Now
As of May 12, 2026, the average gas price in Washington state stands at $5.75 per gallon for regular unleaded, marking a new record high driven by global supply disruptions and state-specific taxes.
Current Prices Overview
Washington state's gas prices have surged dramatically in 2026, with the statewide average hitting $5.75 per gallon on May 11, according to AAA data. This figure surpasses the previous record of $5.67 set just days earlier on May 4. In the Seattle metro area, prices are even higher at approximately $6.19 per gallon, as reported at select stations.
Compared to the national average of $4.53 per gallon, Washington drivers face a premium of over $1.22, largely due to the state's climate tax and gas tax totaling $1.07 per gallon. Only California ($4.83) and Hawaii ($4.48) rank higher nationally.

- Mid-grade: $6.05 estimated average

2026 Price Trends
Gas prices in Washington began 2026 at $3.84 per gallon in late January, bucking a national decline to $2.81. By February, they climbed to $4.33 after a 17-cent weekly jump. March saw further rises to $4.87 by month-end per EIA data.
April escalated with warnings of $10 potential amid Strait of Hormuz tensions, pushing averages to $5.38. May's record $5.67 on May 4 gave way to $5.75 by May 11, up 19 cents weekly due to refinery outages and Middle East conflicts.
| Month | WA Average ($/gallon) | National Average ($/gallon) | Key Event |
|---|---|---|---|
| January 2026 | 3.84 | 2.81 | State policies elevate costs |
| February 2026 | 4.33 | 2.94 | 17-cent weekly surge |
| March 2026 | 4.87 | N/A | Refinery transitions |
| April 2026 | 5.38 | N/A | Geopolitical tensions |
| May 2026 (as of 5/12) | 5.75 | 4.53 | Record high set |
Key Drivers of the Surge
The primary culprit is global oil supply volatility from ongoing Middle East conflicts, including Iran-related disruptions in the Strait of Hormuz, which could push Seattle prices to $10 per gallon if unchecked. Patrick De Haan, GasBuddy's head petroleum analyst, noted, "With so many moving pieces, the outlook remains highly fluid, and broader price volatility is likely to persist."
Washington's unique factors compound this: the cap-and-trade program, now a carbon tax, adds roughly $0.52 per gallon, requiring refineries to buy credits. Combined with the $0.554 gas tax, state levies total $1.07, keeping prices $1.32 above the national average.
- Global refinery outages and seasonal maintenance reduce supply.
- Middle East war escalations, up 50% in national prices since onset.
- State carbon tax and gas tax: $1.07 total add-on.
- Historical context: 2022 peak was $5.56; 2026 shattered it.
- Supply chain bottlenecks from prior years linger.
Historical Context
Washington has long ranked among the priciest states for gas. In 2025, annual average was $4.04 per gallon per EIA, up from $3.92 in 2024. The 2022 record of $5.56 held until May 2026's $5.67 breakthrough.
Energy expert commentary highlights state policies: "It's absolutely because of Washington state's cap-and-trade program...requiring refineries to purchase credits." This system, shared with California, explains why WA ($5.75) outpaces most states despite national drops.
"Washington and California have some of the highest prices because of this new system that essentially requires refineries to purchase credits to operate." - Energy expert, January 2026
Regional Variations
Prices vary sharply within Washington. Seattle stations hit $6.19 as of May 4, while rural areas like Moses Lake saw the statewide record impact. Tacoma averaged $4.47 in February but has risen proportionally.
As of early May, Washington topped state rankings at $4.42 (pre-surge data), ahead of Oregon ($4.02) and Nevada ($3.91). Eastern Washington often sees slight relief, but the May spike erased differences.
- Seattle: Up to $6.19/gallon
- Statewide: $5.75/gallon
- National contrast: $4.53/gallon, 27% lower
- WA vs. OR: $1.73 higher
- Taxes contribution: 19% of pump price
Impact on Drivers
At $5.75 per gallon, a typical 400-mile monthly commute costs drivers an extra $92 compared to January's $3.84, totaling $230 monthly versus $154. Families filling a 15-gallon tank pay $86.25 weekly, up 50% since year-start.
"Sharp increases across the nation...ongoing conflict in the Middle East," notes De Haan, signaling pain at pumps. Washington motorists, already premium payers, face heightened financial strain amid 2026's shocks.
Future Outlook
Experts predict continued volatility. Axios warns of $10/gallon if Hormuz disruptions worsen. Relief may come from refinery restarts post-maintenance, but "localized relief may emerge" per GasBuddy.
