Phoenix Gas Forecast: Doom Or Relief?
Phoenix gas prices are forecasted to drop sharply by late May 2026, falling from the current average of $4.46 per gallon in March to around $3.80 by Memorial Day weekend, shocking drivers expecting continued highs amid geopolitical tensions. This unexpected decline stems from stabilizing oil markets and increased domestic refinery output, despite earlier spikes from the U.S.-Israel actions against Iran. As of May 10, 2026, spot prices at select stations hover near $4.57 for regular unleaded.
Current Snapshot
The average price for unleaded regular gasoline in the Phoenix-Mesa-Scottsdale metro area hit $4.464 per gallon in March 2026, up dramatically from $3.294 in February and $3.043 in January. This surge followed a 25-cent weekly increase tied to Middle East conflicts, pushing some stations above $6 per gallon by early May. Diesel prices, meanwhile, reached $5.54 at locations like Sam's Club in Phoenix.
- Average regular gas: $4.46 (March 2026), 35% above national norms.
- Premium grade: Up to $5.13 at major chains.
- Year-to-date high: $4.11 on March 30, 2026.
- Weekly fluctuation: +32 cents from $3.63 to $3.95 in late spikes.
- Outlier stations: $6.49 reported at Shell on Buckeye Road, April 30.
Historical Trends
Phoenix has long faced elevated gas prices due to its reliance on pipeline imports from California and Texas, with demand surging 16% from 2012-2021 amid 15% population growth. Pressure reductions mandated by PHMSA in late 2021 exacerbated supply constraints, causing spikes like the $5.70 peak in June 2022. Recent data shows volatility: $3.56 in February 2023 nationally comparable, but Phoenix consistently 10-20% higher.
| Month | Price | Change from Prior |
|---|---|---|
| Nov 2025 | 3.532 | +0.285 |
| Dec 2025 | 3.247 | -0.285 |
| Jan 2026 | 3.043 | -0.204 |
| Feb 2026 | 3.294 | +0.251 |
| Mar 2026 | 4.464 | +1.170 |
These figures highlight a 46.7% year-over-year jump by March, driven by seasonal blends and external shocks.
Key Drivers of Prices
Geopolitical tensions, including U.S. and Israeli strikes on Iran in early 2026, disrupted 20% of global oil via the Strait of Hormuz, spiking Brent crude to $119 per barrel on March 9. Arizona's boutique cleaner-burning gasoline (CBG) for air quality adds costs, while Kinder Morgan pipeline limits hinder supply amid booming population. Spring switch to pricier summer-blend fuel and spring break demand compounded the rise.
- Oil market volatility: Iran conflict caused 14% gas price jumps; monitor de-escalation.
- Pipeline constraints: 20% pressure cuts since 2021; trucking costs 10x higher.
- Seasonal factors: Summer blend adds 10-30 cents; peaks in April-May.
- Demand surge: Arizona population +15% (2010-2022) vs. U.S. +8%.
- Refinery shifts: Maintenance and blend changes elevate spring prices.
"Oil prices are determined on a global scale, and oil constitutes the primary component of gasoline. Therefore, when oil prices rise, gas prices will also increase for everyone." - Julian Paredes, AAA spokesperson, March 2026.
Forecast: The Shocking Drop
Experts predict a stunning reversal: Phoenix averages dipping to $3.80-$4.00 by end-May 2026, then $3.09-$3.38 annually, below recent highs as conflicts ease and refineries ramp up. GasBuddy's Patrick De Haan forecasts no repeat of 2022's $5.70 peak, with national averages hitting $3.12 in May before falling to $2.83 by year-end. Tom Kloza of Gulf Oil eyes national $3.25-$3.50 short-term, but Phoenix premiums fade with supply stabilization.
| Period | Low Estimate | High Estimate | Likely Average |
|---|---|---|---|
| May 2026 | 3.75 | 4.00 | 3.88 |
| June Peak | 4.50 | 4.75 | 4.62 |
| Annual Avg | 3.09 | 3.38 | 3.24 |
| Year-End | 2.90 | 3.10 | 3.00 |
This "shock" drop-up to 15% from March-relies on no new disruptions like hurricanes.

- Buy in bulk at warehouse clubs like Sam's ($4.57 recent).
- Avoid highways; urban stations cheaper.
- Combine trips to cut demand 10-15%.
- Consider hybrids for long-term savings amid forecasts.
Expert Insights
Patrick De Haan of GasBuddy warns of April-May climbs to $4.75 but foresees relief: "Prices will continue to climb... peaking in either April or May... but should begin to ease as summer progresses." Tom Kloza adds, "National average to $3.25-$3.50," signaling Phoenix following suit post-peak. Stillwater Associates notes infrastructure fixes needed long-term for Arizona's growth.
These projections, current as of May 10, 2026, underscore volatility-monitor oil at $94.68/barrel levels for shifts.
Broader Impacts
Rising fuel costs strain Valley households, adding $200-300 monthly for 1,000-mile drivers at $4.46/gallon (25 mpg). Businesses face logistics hikes, while tourism dips 5% during peaks. Positive forecast aids recovery, boosting summer travel confidence.
