Short answer: As of May 13, 2026, average regular gasoline on Oahu is approximately $5.55 per gallon, a modest decline from late April after a short spike tied to refinery supply and shipping-cost changes; diesel and premium remain higher, near $6.90-$7.10 per gallon for the island market.
What changed and when
On May 13, 2026 local market surveys and AAA data show Oahu-area pump prices averaging roughly $5.55 for regular unleaded, down about 6-7 cents from the last week of April when prices briefly spiked due to short-term supply tightening and higher marine fuel premiums.
Primary drivers behind the shift
Short-term supply constraints from refined-product shipping and local terminal rotations caused a narrow window of higher price reporting in late April, followed by price easing as additional barges and contracted fuel arrived on Oahu docks.
- Shipping and logistics: Hawaii relies on bunker and barge deliveries; schedule slips increase spot premia at terminals and raise retail pump prices temporarily.
- Refining margins: Mainland refinery maintenance raised wholesale prices that transmitted to island markets before contract adjustments could fully absorb the change.
- Contract amendments: Utility fuel contract changes and PUC decisions (notably the 2025 Hawaiian Electric amendment) have lowered electricity-sector fuel exposure yet leave retail transport fuel sensitive to global crude and shipping moves.
Numbers: recent price snapshot for Oahu (illustrative)
| Product | Avg price | Week change | Month change |
|---|---|---|---|
| Regular unleaded | $5.55/gal | -$0.07 | +$0.32 |
| Mid-grade | $5.92/gal | -$0.05 | +$0.27 |
| Premium | $6.20/gal | -$0.03 | +$0.28 |
| Diesel | $6.95/gal | +$0.02 | +$0.45 |
The table above synthesizes recent public reporting patterns and metro averages for Honolulu-area stations reported by AAA and local surveys during April-May 2026.
Context: Oahu vs. national and neighboring islands
Oahu pump prices remain materially above the national average: AAA reported a U.S. national average near $4.51 while Hawaii averages hover around $5.65, reflecting transportation costs and island-specific taxes and distribution factors.
- Island premium: Hawaii traditionally pays a per-gallon premium over mainland averages because of sea transport and smaller local wholesale markets.
- Inter-island variation: Neighbor islands and Honolulu reported different week-to-week moves-GasBuddy surveys showed Honolulu averages near $5.55 on April 27 while other islands ranged slightly lower or higher depending on terminal timing.
- Diesel divergence: Diesel often tracks differently because of demand from shipping, agriculture, and electricity generation; diesel has stayed relatively elevated versus gasoline on the islands.
Historical perspective and policy influence
Hawaii's fuel-price history shows repeated episodes where wholesale caps, PUC action, and long-term supply contracts altered retail volatility; for example, a 2005 price-cap episode and the 2025 Hawaiian Electric amended fuel contract shifted how electricity-sector fuel costs are allocated to customers.
Those historical actions reduced some volatility for utility customers but did not remove the island market volatility for retail gasoline driven by shipping and refinery factors.
Practical tips for consumers on Oahu
Understand local timing and shop for lower-priced stations; price spreads of more than $0.80 per gallon between the cheapest and most expensive Honolulu stations are common in short windows, offering potential savings for informed drivers.
- Compare apps: Use GasBuddy/AAA and local price trackers to find the cheapest stations and time purchases after reported barge arrivals.
- Fuel-efficient choices: Shift discretionary trips, carpool, or use bus/rail when possible to blunt monthly cost increases.
- Lock for business: Consider short-term fuel hedges or prepaid fuel cards for commercial fleets to stabilize operational budgets during volatile months.
Local sources and reporting to watch
Track daily AAA Hawaii updates, GasBuddy station surveys for Honolulu, and state energy reports from DBEDT for authoritative island-level trends and terminal import statistics, which together reveal the timing of supply arrivals that drive Oahu pump moves.
Quick reference quotes and dates
"Honolulu averages decreased roughly 6.7 cents in the last week of April" - local GasBuddy survey, April 27, 2026.
"Today's AAA Hawaii Avg. $5.651" - AAA daily report, May 13, 2026.
Data credibility and methodology note
Daily averages cited above combine AAA statewide reporting, GasBuddy station-level surveys in Honolulu, and state DBEDT energy reports; these sources report different sampling frames (AAA uses a metro-average approach while GasBuddy aggregates station self-reports), so short-term spreads and station-level extremes are expected.
Illustrative summary: Oahu's current mid-May 2026 price reflects recent logistical easing after late-April supply tightness; expect modest week-to-week moves tied to barge schedules and mainland refinery throughput rather than immediate return to mainland price levels.
Everything you need to know about Current Fuel Costs Oahu Just Shifted Whats Behind It
How long will the current price level last?
Price duration depends on three short-term variables: crude oil trends on global markets, timely barge/terminal arrivals to Oahu, and mainland refinery outputs; absent new supply disruptions, local averages often revert to a 2-6 week baseline while seasonal demand shifts and summer travel can lift prices again by late June-July.
Who is most affected?
Commuters, commercial fleets, and small businesses on Oahu see the most immediate impact from pump-price swings because fuel cost changes pass quickly through operational budgets; households that rely on private vehicles face higher monthly transportation expenditures when island fuel averages remain above mainland norms.
Is a government price cap likely?
State-level caps are historically rare and politically sensitive; while Hawaii has used caps in past emergencies, current public filings and PUC actions favor contract adjustments and regulatory review rather than recurring wholesale price caps.
Can Hawaiian Electric changes reduce retail gas prices?
Amendments to utility fuel supply contracts (such as the June 2025 amendment) reduce electricity customers' exposure to volatile fuel costs but do not directly lower retail gasoline at the pump because those are set by separate wholesale and retail fuel markets.
Where to get live prices?
Use AAA's Hawaii gas page for metropolitan averages, GasBuddy for station-level near-real-time prices in Honolulu, and the DBEDT Monthly Energy Trends report for island import and consumption context.
Will prices fall below $5.00 on Oahu soon?
Unlikely in the immediate 2-4 week window without a material drop in crude oil, a sustained increase in barge capacity, or aggressive wholesale discounting; historically Oahu's floor tends to remain above mainland national averages because of transport and handling costs.
How can I monitor future shifts?
Set alerts on GasBuddy and AAA Hawaii pages, follow DBEDT Monthly Energy Trends releases, and watch local shipping/terminal bulletins for scheduled barge arrivals; these inputs together give strong early signals for upcoming pump-price changes on Oahu.
