Gas Prices in Jacksonville Today

Jacksonville drivers are paying around $3.40 per gallon for regular unleaded as of mid-March 2026, roughly in line with the Florida state average and well below the national average of $3.72. But prices have climbed sharply since the Iran conflict began in early March, with crude oil surging past $110 per barrel and Strait of Hormuz disruptions threatening about 20% of the world's oil transit. Jacksonville's port access provides some supply advantages, but no market is immune to a 26.9% spike in crude costs.

Port City Fuel Access

Jacksonville sits on the St. Johns River with one of the busiest ports on the East Coast. JAXPORT handles fuel imports that supplement the Colonial Pipeline supply feeding most of Florida. This dual supply route, pipeline from the Gulf Coast plus seaborne imports through the port, gives Jacksonville a modest pricing advantage over inland Florida metros that depend entirely on pipeline deliveries.

That port access matters more than usual right now. With global oil markets disrupted by the Iran war and tanker traffic through the Strait of Hormuz under threat, having multiple supply channels provides some insulation against the worst price shocks.

Where to Find the Cheapest Gas in Jacksonville

Jacksonville is the largest city by land area in the contiguous US, and gas prices vary significantly across its sprawling footprint. The Westside and suburban areas south of the city generally offer the lowest prices, while beach communities and the San Marco area run higher.

• Arlington / Regency, 32225, northeast suburban pricing, solid competition
• Fleming Island, 32003, Clay County suburb, often undercuts Duval County prices

The Georgia Border Option

Jacksonville sits just 20 miles south of the Georgia state line, and Georgia's gas prices typically run 15–25 cents below Florida's. Drivers in northern Jacksonville or Nassau County who regularly cross into Georgia for work or shopping can take advantage of this differential. Kingsland and St. Marys stations just across the border on I-95 are popular fill-up spots for Jacksonville commuters heading north.

Florida's Tax Structure and Gas Prices

Florida has no state income tax, but its gas tax sits around 36 cents per gallon, moderate by national standards. Georgia's gas tax is lower at 29.1 cents per gallon, which accounts for much of the cross-border price difference. Florida legislators periodically debate gas tax holidays, but as of March 2026 no such relief is in effect to offset the Iran-driven price surge.

Seasonal Demand Patterns

Jacksonville experiences less extreme seasonal swings than South Florida tourist markets like Miami or Orlando. But spring and summer still bring increased driving along I-95 and I-10, and the current price environment, already elevated from the Middle East crisis, will likely worsen as summer travel ramps up.
