Yes, summer travel season will likely bring gas price spikes, though predictions vary widely depending on global events and market conditions. As of May 2026, the national average gas price stands at $4.55 per gallon—a substantial jump from last year’s prices. In Kentucky, drivers face prices of $4.31 per gallon, up $1.47 compared to the same period in 2025, meaning a typical road trip to the beach or mountains will cost significantly more than it did a year ago.
The critical question for millions of Americans planning summer vacations is not whether prices will spike, but how high they might climb. The U.S. Energy Information Administration (EIA) has provided multiple scenarios, and the uncertainty itself reflects broader market instability. Unlike typical forecasts that offer a single expected outcome, current projections show a range from modest relief to potential price shocks, depending on factors largely outside domestic control—particularly global oil supply disruptions and geopolitical tensions affecting the Strait of Hormuz.

What Are Current Gas Prices and How High Could They Go?
The gap between official EIA projections and real-world pump prices reveals a disconnect worth examining. The EIA forecasts gasoline will average $3.638 per gallon in May 2026, yet actual prices are already running significantly higher at $4.55 nationally. This 90-cent discrepancy matters because it signals either that forecasts are overly optimistic or that real-time market conditions include factors the models didn’t fully anticipate. For consumers, it means planning a 2,000-mile summer road trip based on EIA averages could leave your household budget short by hundreds of dollars. Expert predictions for summer pricing diverge dramatically.
GasBuddy projects prices may dip into the $3.20s during the seasonal gasoline blend switch, likely declining after June. However, other analysts are less optimistic, with some forecasting prices could remain in the $3.50 to $3.80 range through much of June depending on crude oil trajectory. The worst-case scenario—one that AAA acknowledges as possible—is prices reaching $5 per gallon or higher if the Strait of Hormuz remains closed. A family of four paying $5 per gallon instead of $4.55 would spend an extra $135 on a 1,000-gallon summer fuel budget, effectively funding several additional vacation expenses or canceling trips altogether. The unpredictability itself is a risk factor. AAA stated bluntly: “Because the situation is changing so quickly, AAA can’t predict how high prices might go.” This admission reflects the reality that oil markets respond to geopolitical events in real time, and forecasters working with outdated assumptions provide false confidence to consumers planning major purchases.
How Geopolitical Events Are Influencing Gas Prices
The Strait of Hormuz closure has become the dominant wildcard in summer gas price forecasts. This narrow waterway between Iran and Oman handles roughly one-third of all seaborne traded oil globally, and any disruption creates an immediate supply shock that ripples through pump prices within weeks. The closure is not hypothetical; it’s actively constraining global oil supply and creating the uncertainty that has led AAA and other experts to essentially throw up their hands at precision forecasting. Oil prices climbing above $100 per barrel amplify this pressure. Higher crude prices flow directly to the refinery, creating upward pressure at the pump.
The relationship is not perfectly linear—refinery capacity, seasonal maintenance schedules, and profit margins complicate the math—but the direction is consistent. When crude breaches $100, consumers should expect their next fill-up to feel noticeably more expensive. Compounding this, the EIA’s own forecasts show oil prices will remain elevated, meaning the structural pressure on gasoline prices will persist through the summer travel season rather than providing relief as driving season winds down. The limitation of discussing geopolitical factors is that Americans have zero control over Middle Eastern tensions or supply corridor disruptions. Unlike gas taxes or fuel economy standards—policy levers that exist within the domestic political system—the Strait of Hormuz situation is largely determined by international actors and events. Consumers can only adjust their behavior and expectations, not influence the underlying cause.
Summer Seasonal Factors and Travel Impact
Summer brings predictable seasonal demand increases for road trips, vacations, and leisure driving. These increased volumes create upward pressure on prices ahead of peak season as refineries adjust production mix and retailers prepare for higher volumes. Historically, pump prices rise 20 to 40 cents per gallon between late spring and mid-summer simply due to seasonal demand. In 2026, this natural seasonal increase is layered atop already-elevated prices, creating a compounding effect. GasBuddy analyst Patrick De Haan advised travelers to “prepare to pay more and set aside extra funds for summer road trips.” This isn’t alarmism; it’s acknowledgment that summer 2026 will be more expensive than most recent years for driving-based vacations.
A family planning a week-long road trip should budget for $4.50+ per gallon, not the $3.50 or lower prices that were common before 2024. This changes vacation planning calculus: flights become more competitive with driving for longer distances, family road trips requiring multiple fill-ups become luxury items rather than affordable getaways, and consumers in rural or exurban areas—where driving distances are longer—face disproportionate impacts. The example of Kentucky is instructive. With gas $1.47 higher per gallon than last year, a typical Kentucky driver purchasing 15 gallons per week spends an extra $22 weekly, or roughly $1,100 over a 50-week period. For middle-income households, that’s substantial money redirected from discretionary spending to fuel costs. For low-income households, it forces genuine tradeoffs between driving to work and other basic expenses.
What Consumers Should Expect and How to Prepare
The EIA’s mid-range projection suggests monthly average prices may peak near $4.30 per gallon around April (though current prices are already above that), then average more than $3.70 per gallon for the year. For summer specifically, June could see prices between $3.50 and $3.80 depending on events, though this forecast comes with substantial caveats given the Strait of Hormuz uncertainty. Practically speaking, consumers should plan for $4+ per gallon throughout summer and view any lower prices as welcome relief rather than the norm. Preparation strategies differ by vehicle type and trip distance.
For vehicles with poor fuel economy, ridesharing or flying becomes cost-competitive at current prices. A 300-mile road trip in a 20-mpg SUV costs roughly $60 in gas at $4.55 per gallon, versus $400+ in flights when adding airport transportation, parking, and fees—but a 1,000-mile trip tips toward flying at current prices. For households planning longer road trips, advance fuel purchases at lower-price periods (early mornings, mid-week) provide modest savings of a few percent, and app-based price tracking can identify 10-20 cent variations between nearby stations. The tradeoff is that some forecasts suggest waiting for the blend switch in June might provide temporary relief to the $3.20-$3.80 range, but betting on price declines is risky given geopolitical headwinds. Locking in fuel costs through rideshare or flight alternatives may be prudent for families that can adjust their plans.
The Gap Between Official Forecasts and Current Reality
The EIA forecast of $3.638 for May 2026 missed the actual May national average of $4.55 by more than 90 cents per gallon. This discrepancy suggests either the forecasting models lag real-time market developments, or the EIA’s projections assumed resolution of geopolitical tensions that haven’t materialized. For consumers relying on official government forecasts to plan budgets, this gap is a limitation worth understanding: EIA projections are useful directional guidance, not precise price predictions. Industry analysts like GasBuddy face similar uncertainty. Their projections of potential dips to the $3.20s depend on “seasonal gasoline blend switches” occurring as planned and broader geopolitical stability materializing.
If the Strait of Hormuz closure persists or deepens, these optimistic scenarios evaporate. The honest acknowledgment from multiple forecasters is that 2026 is simply more uncertain than typical years, making historical relationships between crude prices and pump prices less reliable than normal. This limitation affects policy too. If government agencies, industry associations, and private forecasters all struggle to predict prices within 90 cents per gallon, then policy responses—whether price controls, fuel tax suspensions, or strategic petroleum reserve releases—operate in an information vacuum. Policymakers may undertake costly interventions based on forecasts that miss actual conditions by wide margins.
Year-Over-Year Context and Market Projections
The EIA projects gasoline prices will fall 6 percent in 2026 compared to 2025, but then increase 1 percent in 2027. This year-over-year comparison is important context: while summer 2026 prices feel punitive to consumers accustomed to lower prices from a few years ago, they’re actually declining relative to 2025 levels. The problem is that 2025 itself had elevated prices, so a 6 percent decline still leaves 2026 expensive in historical terms.
For example, if 2025 averaged $4.85 per gallon, a 6 percent decline puts 2026 at roughly $4.56—approximately where May prices currently sit. This means summer may not see the improvements some forecasters imply; instead, prices may simply track near current levels for several months. The forward-looking concern is the 2027 increase, which suggests market fundamentals remain tight and upward price pressure persists beyond the 2026 summer season.
What Happens After Summer—Fall and Beyond
As summer travel season winds down in September, historical patterns suggest gas prices typically decline 20 to 40 cents per gallon simply due to reduced seasonal demand. However, this pattern assumes normal refinery operations and stable oil supply, neither of which is certain in 2026 given geopolitical tensions. If the Strait of Hormuz remains constrained through fall, the typical seasonal relief may not materialize. The longer outlook depends largely on factors beyond the U.S.
government’s direct control. A resolution of Middle Eastern tensions would provide substantial relief, potentially bringing prices down toward the EIA’s lower forecasts. Continued tension or further supply disruptions could extend elevated prices through 2027. For consumers, this suggests preparing for sustained high fuel costs through the winter and avoiding assumptions that fall and winter will bring the traditional seasonal price declines of recent years.
Conclusion
Summer 2026 will almost certainly bring gas price spikes from a historical perspective, though the precise magnitude remains uncertain. Current prices of $4.55 nationally and $4.31 in Kentucky are substantially elevated compared to last year, and the range of expert forecasts ($3.20s to $5+) reflects genuine uncertainty driven by geopolitical factors largely outside domestic control. Families planning summer travel should budget for $4+ per gallon, prepare contingency plans if prices approach $5, and recognize that traditional seasonal patterns may not provide the relief they’ve come to expect in previous years.
The key takeaway is that 2026 gas prices are fundamentally different from the pre-2022 era when forecasts were more predictable and geopolitical shocks less frequent. Even official government forecasts are running 90 cents off actual prices, signaling that consumers should plan conservatively and avoid assuming prices will decline rapidly once summer ends. Road trips aren’t impossible—millions will still take them—but they’ll be noticeably more expensive than the historical average, and families should adjust vacation budgets and travel planning accordingly.
