Weekly Trends
Phoenix gas prices have climbed steadily this week, with regular jumping from $4.09 a week ago to $4.41 today, a 7.8% increase tied to OPEC supply cuts. Diesel saw the sharpest rise at 8.5%, reflecting broader freight demand in the Southwest.
- April 30: Average regular at $4.23, pre-OPEC announcement stability.
- May 4: Spike to $4.49 at many Valley pumps after oil hit $86/barrel.
- May 8: Current $4.41, with forecasts holding through Memorial Day.
- Projected May 15: Potential drop to $4.30 if refineries resume full output.
- Historical Peak: $5.39 in June 2022, unlikely to repeat this cycle.
Factors Driving Prices
The surge in Phoenix AZ gas prices stems from multiple layers: crude oil at $85-86 per barrel accounts for $2.04/gallon base cost, refinery processing adds 50-70 cents, and Arizona's 18-cent state tax plus 18.4-cent federal levy pushes totals higher. Regional issues, like spring maintenance shutdowns in Texas and New Mexico, have tightened summer blend gasoline supply by 15%.
"The cost of crude oil today was like $85/$86 on average, which would give you a built-in cost of probably $2.04 a gallon just for the crude oil," explained industry expert Donnellan.
Historical Context
Phoenix has endured cyclical high gas prices, ranking third nationally behind California and Hawaii at times. In June 2022, averages hit $5.39 amid post-pandemic demand; 2023 saw $4.70 statewide, over $1 above national norms. Year-to-date 2026 peaked at $4.11 for regular on March 30, down from $5.23 highs at outlier Mesa stations.
- 2022 Peak: $5.39 average, driven by Ukraine conflict oil shocks.
- 2023 Average: $4.58 in April, summer blend transition culprit.
- 2025 YTD: Stabilized at $3.92 diesel low before recent climb.
- 2026 Trend: +12% YOY, correlating with 8% crude rise.
