Historical Trends Table
Honolulu's fuel prices have surged 25% year-over-year from May 2025's $4.48 average, driven by refined product shortages and Pacific shipping costs.
| Period | Regular ($/gal) | Premium ($/gal) | Diesel ($/gal) | Change from Prior |
|---|---|---|---|---|
| Today (May 8, 2026) | 5.623 | 5.911 | 7.149 | +0.014 (week) |

| Week Ago | 5.609 | 5.905 | N/A | -0.029 (month) |
| Month Ago | 5.557 | 5.823 | N/A | +0.066 |
| Jan 2026 Low | 4.42 | N/A | N/A | Four-year low |
Why Prices Are Stubbornly High
Despite a national average of $4.546, Honolulu's isolation amplifies costs, with 90% of fuel imported via tanker from the mainland. Recent refinery maintenance on the West Coast added 12 cents per gallon last week alone.
"Shipping delays from Los Angeles refineries are the real culprit," says Lauro Angeles, AAA Hawaii spokesperson, noting a 3.2% hike in freight rates since April 15, 2026. Local wholesalers face caps from the Hawaii Public Utilities Commission, but retail markups persist.
"The statewide average dipped briefly to $4.40 in early January, the lowest since 2022, but logistics volatility erased those gains."

Impact on Honolulu Drivers
A typical commuter filling a 15-gallon tank now pays $84.35 weekly, up $10 from last month, straining household budgets amid 4.1% inflation. Ride-sharing services like Uber have raised fares 8% in response.
Tourism, Hawaii's economic backbone, sees visitors grumble: "Expected aloha, got pump shock," per a TripAdvisor review spike on May 7. Electric vehicle adoption lags at 2.3% of registrations, limiting relief.
Policy and Future Outlook
Hawaii's 2026 Energy Plan targets 30% renewable transport fuel by 2030, but current EV infrastructure covers just 15% of stations. Governor's office pushes tax credits for hybrids, effective July 1.
- Import reliance: 90%+ from mainland
- Wholesale cap: ~$3.50/gal base (adjusted weekly)
- Renewable goal: Biofuel blend at 15% by 2028
- EV chargers: 450 new installs planned H2 2026
Experts like Dr. Camille Perino from UH Manoa predict a plateau at $5.50 through summer, barring hurricanes disrupting Pacific routes: "Climate risks amplify every tanker delay."
