Gas Prices in St. Augustine, FL Today

St. Augustine drivers are paying around $4.25 to $4.45 per gallon in May 2026, slightly below Jacksonville and roughly in line with the broader northeast Florida I-95 corridor. The historic district carries a small visible tourist premium at a handful of stations, but St. Augustine is fortunate to sit close enough to Jacksonville's fuel infrastructure that most stations track competitive regional pricing rather than the captive-island pricing that hits the Florida Keys.

Why St. Augustine Tracks Jacksonville More Than the Keys

St. Augustine is roughly 40 miles south of Jacksonville's Port of Blount Island fuel terminal, where most northeast Florida gasoline arrives by tanker from Gulf Coast refineries. That short overland delivery distance means stations here see resupply nearly as fast and cheaply as Jacksonville suburbs, and the price difference between the two metros usually runs 5 to 10 cents at most.

Florida's 36.4 cent state gas tax applies uniformly. St. Johns County adds local option fuel taxes that put the total state and local burden slightly higher than Duval County (Jacksonville). That's why St. Augustine stations often run a few cents above Jacksonville exurbs despite the otherwise similar supply chain.

Where to Find Cheaper Gas in St. Augustine

The metro covers Historic St. Augustine, St. Augustine Beach, and the inland suburbs along I-95 and US-1.

• West St. Augustine / I-95 corridor, 32084, the most competitive pricing in the metro, high-volume stations with short refill cycles
• South St. Augustine / SR-312 area, 32086, reliable mid-range pricing
• St. Augustine Beach, 32080, beachside stations carry 10 to 20 cent tourist premium, particularly on A1A
• World Golf Village area, 32092, suburban Sam's Club / Costco-style high-volume corridor, often the cheapest
• North St. Augustine / Vilano Beach side, 32084, mixed pricing depending on station

Practical Tips for St. Augustine Drivers

If you're visiting and parking near the Historic District, fill up before you arrive at one of the I-95 corridor stations. Stations within the old town walking radius cater to a captive tourist population and run 10 to 25 cents above stations 3 miles inland. The Costco location at World Golf Village is the cheapest reliable fill in St. Johns County and is worth the detour for a full tank.

Year-round residents benefit from the Sam's Club and BJ's Wholesale options along the I-95 corridor, both of which run 25 to 40 cents below the local retail average. Loyalty programs at Wawa and Murphy USA also stack visible savings if you fuel weekly.

Tire maintenance matters in Florida humidity: heat causes valve seal failures and slow leaks faster than drier climates. A monthly check with a pressure gauge prevents 2 to 3 percent MPG loss from underinflation. A fuel system cleaner every 3 to 4 months keeps injectors clean and helps maintain MPG on older vehicles.

Tourist Season Pricing

St. Augustine runs two distinct peak seasons: late spring (March through May, driven by school break travel) and the late-fall and winter snowbird season (November through February). Both push beachside and historic-district stations into a sustained 10 to 15 cent premium versus the I-95 corridor. The inland ZIPs run more stable pricing year-round.
