Arizona gas prices are forecast to rise next week, with the average for regular unleaded expected to reach **$3.63-$3.66 per gallon** by May 12-18, 2026, up 5-8 cents from the current **$3.58 per gallon** average reported May 8, 2026. This uptick stems from higher crude oil prices, spring driving demand, and the mandatory switch to more expensive summer-blend fuel across the state. AAA Arizona expects prices to continue climbing but at a slower pace through late May, remaining roughly 20 cents above the national average.
Current Arizona Gas Price Snapshot
As of Friday, May 8, 2026, Arizona's average gas price for regular unleaded stands at $3.58 per gallon, marking a 17-cent increase from the prior week. This price surge reflects broader market dynamics including geopolitical tensions and seasonal fuel transitions.
- Regular unleaded average: $3.58/gallon (May 8, 2026)
- Weekly change: +17 cents from May 1, 2026
- National average comparison: ~20 cents higher than U.S. average
- Year-to-date increase: Approximately $1.29 since early January 2026
- Peak 2026 price so far: $3.66 projected for May 15, 2026
Maricopa County, home to Phoenix, faces even steeper costs, averaging $3.72 per gallon-among the highest in the state. Tucson residents pay slightly less, around $3.48 per gallon, while Flagstaff stations average $3.89 due to regional supply constraints.
| Metro Area | Regular Unleaded Average | Weekly Change | Versus State Average |
|---|---|---|---|
| Phoenix (Maricopa County) | $3.72/gallon | +19 cents | +14 cents |
| Tucson (Pima County) | $3.48/gallon | +15 cents | -10 cents |
| Flagstaff (Coconino County) | $3.89/gallon | +21 cents | +31 cents |
| Yuma | $3.54/gallon | +16 cents | -4 cents |
| Statewide Average | $3.58/gallon | +17 cents | - |
Next Week's Forecast: May 12-18, 2026
Analysts project Arizona's gas prices next week will continue their upward trajectory, driven by three primary factors: rising crude oil costs, seasonal demand spikes, and refinery maintenance in the Southwest. AAA Arizona spokesman Julian Paredes stated, "Prices will continue to climb, but likely at a slower pace," indicating a more gradual increase than the 17-cent jump seen this past week.
- May 12 (Monday): $3.60/gallon - Initial uptick as summer blend fully takes effect
- May 13 (Tuesday): $3.61/gallon - Continued pressure from crude oil futures
- May 14 (Wednesday): $3.63/gallon - Midweek demand surge from commuters
- May 15 (Thursday): $3.65/gallon - Pre-weekend price adjustment
- May 16-18 (Weekend): $3.66/gallon - Peak for the week amid spring travel
This forecast assumes crude oil remains above $85 per barrel and no unexpected refinery outages occur. The summer-blend transition typically adds 3-5 cents per gallon in May as refineries switch to cleaner-burning fuel required by EPA regulations.
Key Drivers Behind Rising Prices
Several concurrent factors explain Arizona's fuel cost increase in early May 2026. First, crude oil prices have risen due to ongoing geopolitical tensions, including U.S.-Israel strikes on Iran that disrupted supply expectations. Second, spring driving season has begun, increasing demand as families embark on road trips and school ends. Third, Southwest refineries are undergoing routine maintenance, creating temporary supply shortages.
"There are three primary factors in the steady increase of gas prices in the state: seasonal demand, oil prices and refinery maintenance." - Julian Paredes, AAA Arizona spokesperson
The war in Ukraine and Middle East conflicts have also impacted global oil prices, forcing refiners to adjust pricing across all regions including Arizona. Additionally, Arizona's dependence on a limited number of refineries makes the state more vulnerable to supply chain disruptions than states with diverse refining capacity.
How Arizona Compares Nationally
Arizona's gas prices remain elevated compared to the national average, which sits around $3.38 per gallon for regular unleaded as of May 2026. This 20-cent premium reflects Arizona's unique combination of remote geography, limited refining infrastructure, and stringent environmental fuel requirements.
| Region | Regular Unleaded Average | Weekly Change |
|---|---|---|
| Arizona Statewide | $3.58/gallon | +17 cents |
| National Average (U.S.) | $3.38/gallon | +12 cents |
| California | $4.89/gallon | +15 cents |
| Texas | $2.98/gallon | +10 cents |
| Neighboring New Mexico | $3.29/gallon | +14 cents |
California remains the most expensive state at $4.89/gallon, while Texas offers the lowest prices among neighboring large states at $2.98/gallon. Arizona ranks approximately 18th highest nationally, behind Pacific and Northeast states but ahead of most Southern and Midwestern regions.
Historical Context: 2026 Price Trends
Arizona gas prices have experienced significant volatility in 2026. Prices started the year at $2.98 per gallon in early January, then spiked more than $1 after the U.S.-Israel strikes on Iran in late March. The January low of $0.98 per liter (~$3.71/gallon) contrasts sharply with the May 4, 2026 high of $1.44 per liter (~$5.45/gallon) in Octane-95 data.
Regular unleaded followed a similar pattern, increasing 42 cents per gallon in April alone during one particularly sharp rise. The year-to-date swing of over $1.29 represents one of the most dramatic price movements in recent Arizona history. Historically, Arizona sees its highest prices in June-July during peak summer travel, so May's rise aligns with seasonal patterns.
When Will Prices Drop?
Most analysts do not expect significant price drops until late June or early July 2026, after the Memorial Day travel surge subsides and refineries complete maintenance. Some Gasbuddy analysts predict prices could fall 10-15 cents by mid-July if oil prices stabilize and demand normalizes.
However, geopolitical risk remains a wildcard. Any escalation in Middle East conflicts could push prices higher again, potentially exceeding $4.00/gallon statewide. The forward outlook remains cautious, with most forecasts predicting sustained elevated prices through summer 2026.
Saving Money on Gas in Arizona
While consumers cannot control global oil markets, experts recommend several strategies to reduce fuel expenses. GasBuddy analyst Gregg Laskoski suggests checking tire pressure, replacing air filters, and avoiding rapid acceleration or braking to improve mileage.
- Use smartphone gas apps to find the lowest prices near your location
- Fill up early in the week, as prices often rise toward weekends
- Drive in Tucson or Yuma when possible instead of Phoenix metro
- Combine errands to reduce total miles driven during high-price periods
- Consider public transit or carpooling for daily commutes in Maricopa County
These tactics can save drivers 5-15 cents per gallon effectively, even when pump prices rise. Timing your fill-ups by just 2-3 days can also yield noticeable savings given the weekly price volatility.
Conclusion: What to Expect Through May 2026
Arizona drivers should prepare for continued gas price increases through mid-to-late May 2026, with regular unleaded likely reaching $3.66/gallon by the weekend of May 16-18. The combination of seasonal demand, summer-blend fuel, and geopolitical pressure creates a challenging market environment.
While prices may stabilize by late June, significant drops remain unlikely before July 2026. Staying informed about weekly trends and using cost-saving strategies can help Arizona residents manage higher transportation costs during this period.
