| Region | Today ($) | Week Ago ($) | % Change |
|---|---|---|---|
| Phoenix | 4.92 | 4.78 | +2.9% |
| Tucson | 4.76 | 4.69 | +1.5% |
| Flagstaff | 4.88 | 4.82 | +1.2% |

| State Avg | 4.83 | 4.72 | +2.4% |
"The recent spike reflects tighter refinery output post-spring maintenance," notes AAA analyst Maria Contreras in a May 7 statement. Historical peaks, like June 2022's $5.39, loom as warnings if geopolitical tensions escalate.
Monthly and Yearly Analysis
Month-over-month, prices edged up 1.6% from April's $4.75 average, bucking seasonal norms where May typically sees relief. Year-over-year, the 15.6% jump stems from 2025's supply disruptions, including Hurricane impacts on Gulf refineries affecting Southwest pipelines.
- January 2026: $3.85 (post-holiday low)
- February: $3.95 (+2.6% amid winter demand)
- March: $4.46 (+12.9% refinery switchovers)
- April: $4.75 (+6.5% summer blend transition)
- May 8: $4.83 (+1.6% current)
FRED economic data for Phoenix shows unleaded regular at $4.464 in March, climbing steadily into spring. This trajectory suggests $5.00 by Memorial Day if oil holds above $80.
Key Drivers Behind the Surge
Rising crude oil prices, now at $82.50 per barrel (WTI), account for 60% of the pump increase, per U.S. Energy Information Administration models. Arizona's reliance on California and Gulf Coast refineries amplifies effects from regional outages.
- Refinery maintenance: 12% capacity offline in Q2 2026
- Geopolitics: OPEC+ cuts extended through June
- Demand rebound: Spring break travel up 8% YoY
- Taxes stable: 18.9¢ federal + 19¢ state unchanged
"Drivers in the Southwest face a perfect storm-higher crude, logistical bottlenecks, and no new pipelines since 2023," says petroleum economist Dr. Lena Torres, University of Arizona.
Regional Variations
Maricopa County leads with $4.91 averages, driven by commuter demand, while Pima County lags at $4.76 due to lower tourism. Flagstaff's elevation and winter stockpiles keep it at $4.88, 1% above state norms.
| County | Avg Price ($) | vs State | Top Station |
|---|---|---|---|
| Maricopa | 4.91 | +1.7% | Scottsdale: $5.02 |
| Pima | 4.76 | -1.5% | Tucson: $4.82 |
| Coconino | 4.88 | +1.0% | Flagstaff: $4.95 |
| Yuma | 4.65 | -3.7% | Yuma: $4.68 |
| Mohave | 4.72 | -2.3% | K. Havasu: $4.78 |
Cheapest gallons cluster at Costco and QuikTrip outlets, often 20¢ below independents. Rural differentials widen: Prescott at $4.69 vs. urban premiums.
Forecast for Next 30 Days
Analysts project a 5-8% rise to $5.07-$5.22 by early June, contingent on oil stabilizing under $85. EIA's Short-Term Energy Outlook predicts peak summer demand pushing Arizona to $5.35 absent relief. A mild downside risk exists if Canadian imports surge 10%.
Historical May trends show +4.2% averages since 2020, with 2022's 18% outlier from Ukraine shocks. Monitor OPEC meetings on May 15 for volatility cues.

"Patterns repeat-spring transitions ignite 10-15% runs," reflects 20-year veteran pump watcher Tom Reilly, AZ Fuel Association.
National Comparison
Arizona ranks pricier than Texas ($4.32) or Oklahoma ($4.15) but below California's $5.89. National $4.546 average trails due to Midwest refinery density. Southwest isolation costs 12-18¢ extra statewide.
