Tucson Gas Prices Tick Down Over the Week, Still Markedly Higher Than a Year Ago
Drivers in the Tucson metropolitan area saw the average price for a gallon of regular gasoline fall modestly over the last week, with the prevailing retail price measured at $4.58 as of June 1, 2026. That figure is 11 cents lower than the price reported a week earlier, reflecting a 2.4% decline over seven days. Despite the short-term dip, the price level is substantially higher than it was a year ago, representing a $1.59 increase — a 53.0% jump compared with the same date in 2025.

On a statewide basis, the typical price in Arizona registers a bit higher than in Tucson, with the state average at $4.68 per gallon. Tucson’s retail price therefore sits 10 cents below that statewide figure. Looking back over recent years, the most expensive regular gasoline price recorded in the region was $4.98 on June 17, 2022; the current Tucson average is 40 cents lower than that historical peak.
Fuel for commercial and heavy-duty vehicles also showed a small weekly decline. Diesel averaged $5.69 per gallon in the Tucson area on June 1, down three cents from the prior week, a 0.5% decrease. Compared with the same point last year, diesel is markedly higher — rising $2.38, a 72.0% year-over-year increase. Diesel’s most recent high-water mark came on April 10, 2026, when the retail average reached $6.00 per gallon; the current level is 31 cents below that recent high.
Across the country, there is still a wide gap between the least and most expensive metro areas for regular gasoline. At the low end, several Midwestern metros report the cheapest pump prices: Kokomo, Indiana, and Fort Wayne, Indiana, both show averages of $3.54 per gallon, and Gary, Indiana, posts $3.55. By contrast, a number of California metros remain at the top of the list for costly fuel. The five most expensive metropolitan areas for regular gasoline are led by Napa at $6.28 per gallon, followed by Santa Cruz-Watsonville at $6.22, San Luis Obispo-Atascadero-Paso Robles and San Francisco tied at $6.20, and Salinas at $6.18.
The difference between Tucson’s average and the priciest metro — Napa at $6.28 — measures $1.70 per gallon. Those regional disparities reflect how local markets can diverge sharply from the statewide and national pictures on any given day.

The most recent seven-day decline in Tucson’s regular gasoline price erased a small portion of the gains recorded over the preceding 12 months, but prices remain well above the levels motorists paid in mid-2025. Diesel’s week-to-week movement was smaller in absolute terms, though its year-to-year rise is larger in percentage terms than that of regular gasoline. These metrics offer a snapshot of retail pump conditions in the Tucson metro for the start of June 2026: regular gasoline at $4.58 and diesel at $5.69, with short-term easing contrasted against substantial year-over-year increases and with regional extremes ranging from roughly $3.54 to $6.28 per gallon.
