May 2026 has seen relentless upward pressure on gas prices, starting at $4.64 on May 1 and climbing to the current $4.85 by mid-month, a 4.5% monthly gain.

| Date | Regular ($/gal) | Premium ($/gal) | Change from Prior Month |
|---|---|---|---|
| May 1, 2026 | 4.64 | 4.98 | +0.19 |
| May 7, 2026 | 4.72 | 5.05 | +0.25 |
| May 13, 2026 | 4.85 | 5.14 | +0.38 |
| Projected May 31 | 4.95 | 5.25 | +0.48 |
Historical context shows this May's averages surpassing 2025's $4.12 peak by 18%, fueled by persistent supply chain issues from Southern California refineries.
Key Factors Driving Prices
- Refinery Maintenance: Major facilities in Southern California, which supply 90% of Arizona's fuel, underwent unscheduled downtime in early May, reducing output by 15%.
- Summer Blend Switch: The mandatory shift to pricier summer-blend gasoline (lower volatility) added 20-30 cents per gallon starting April 15.
- Crude Oil Volatility: Brent crude hovered at $86/barrel on May 10, up 12% from April, due to OPEC+ cuts and Middle East tensions.
- Arizona Taxes and Fees: State excise tax at 18 cents/gallon, plus federal 18.4 cents and environmental fees, totals 37 cents-higher than neighboring states.
- Demand Surge: Phoenix's population boom (adding 50,000 residents yearly) and spring break travel spiked consumption by 8%.
"Arizona is at a major disadvantage... refineries in Southern California are undergoing major maintenance, and we sit at the end of pipelines," says Patrick De Haan, GasBuddy head of petroleum analysis.
Historical Comparison
Phoenix gas prices in May 2026 dwarf recent years: $4.85 regular vs. $3.95 in May 2025, $4.23 in May 2024, and the all-time high of $5.70 in June 2022. This year's spike echoes 2022's post-pandemic crunch but is tempered by improved domestic production.
Compared to peers, Phoenix trails only California ($5.42) and Hawaii ($5.18), while Tucson averages a more palatable $4.64. Nationally, the U.S. average of $4.63 ranks Arizona third priciest.
Cost Impact on Households
For the average Phoenix commuter driving 15,000 miles yearly at 25 MPG, May's $4.85 gas translates to $2,910 annually-$450 more than 2025. Families filling a 15-gallon tank weekly face $375 monthly, straining budgets amid 3.2% regional inflation.
Utility bills compound this, with APS electricity up 7% and water rates rising 5% in 2026, per city council data. Low-income drivers in South Phoenix neighborhoods report cutting groceries to cover fuel.
Tips to Save on Gas
- Avoid idling: Saves 5-10 cents/gallon equivalent per hour.
- Use apps like GasBuddy: Find stations 20-30 cents cheaper, e.g., $4.55 vs. $4.85.
- Maintain tires: Proper inflation boosts MPG by 3% (0.1 gal savings/10 miles).
- Drive 55-65 mph: Reduces consumption 15% vs. 75 mph highway speeds.
- Combine trips: Cuts fill-ups 20% for weekly commuters.
Regional Breakdown
Prices vary sharply within the Valley: Scottsdale averages $4.98, Tempe $4.87, while Glendale offers $4.76 lows. Maricopa County mandates exceed Yuma's $4.29 by 56 cents due to urban density.
| Area | Regular ($/gal) | Diesel ($/gal) | Cheapest Station |
|---|---|---|---|
| Phoenix Proper | 4.88 | 4.75 | $4.62 (Costco) |
| Mesa | 4.92 | 4.78 | $4.65 (QuikTrip) |
| Scottsdale | 4.98 | 4.82 | $4.71 (Shell) |

Expert Forecasts and Outlook
Tom Kloza of Gulf Oil predicts national averages hitting $4.75 by July if oil stays above $85/barrel, with Phoenix potentially touching $5.10. Conversely, Julian Paredes of AAA sees relief by August as inventories rebuild.
"Prices should ease into fall, but expect volatility from election-year policies," notes Patrick De Haan. Long-term, Arizona's push for cleaner fuels may add 10 cents permanently.
Broader Economic Ripple
These high gas prices inflate Phoenix's CPI by 0.8 points, hitting retail and dining hardest-grocery deliveries up 12%. Tourism thrives, but locals curb discretionary drives, boosting rideshares 15%.
Statewide, Arizona's $4.72 average trails California's $5.42 but exceeds Nevada's $4.51, per GlobalPetrolPrices. Policymakers eye tax holidays, as proposed May 10 by Gov. Hobbs.
"OPEC cuts and regional supply issues account for 60% of the climb-drivers, buckle up," warns oil analyst Donnellan.
