Yes, gas prices are significantly higher heading into summer 2026, and they will make your road trips noticeably more expensive than they were just a year ago. The national average gas price hit $4.55 per gallon as of May 7, 2026—up 25 cents in just one week—and sits $1.40 higher than May 2025. This represents a 53% price increase from the lows of late February, when gas averaged just $2.96 per gallon.
For families planning summer road trips, these elevated prices mean a 1,000-mile round trip that cost $80 in gas in 2023 will now run $100 to $110, a 25-37% increase in fuel expenses alone. The cost increases extend beyond just the pump. AAA reports that the average summer vacation now costs $7,249—up 11% from 2024 and more than double the cost from 2022. Supply constraints from the Strait of Hormuz closure and reduced crude oil flows are driving much of the current spike, and energy analysts expect gas prices to remain above $4 per gallon through the entire summer season, with some forecasts suggesting they could potentially reach $5 per gallon if geopolitical tensions persist.

How Much Have Gas Prices Actually Risen Since Last Year?
The year-over-year comparison is stark. One year ago in May 2025, drivers were paying approximately $3.15 per gallon on average. Today, that same gallon costs $4.55—a difference of $1.40 per gallon. On a typical 15-gallon fill-up, that’s an additional $21 per tank. For someone taking a 1,000-mile summer road trip with a vehicle averaging 25 miles per gallon, the difference between 2025 and 2026 fuel costs translates to roughly $56 extra just for gas—and that’s using the current prices, not accounting for further increases. What makes this particularly striking is the speed of the increase.
In just over two months—from late February to early May—gas prices climbed from $2.96 to $4.55 per gallon. That 53% spike happened faster than most consumers could adjust their vacation budgets or travel plans. Energy Information Administration data shows this is not a gradual seasonal trend but a sharp, sustained movement upward driven largely by reduced crude oil supplies flowing through the Strait of Hormuz. The regional impact varies significantly. Californians are paying the most at $6.16 per gallon, followed by Washington at $5.76, Hawaii at $5.66, Oregon at $5.34, and Nevada at $5.23. Meanwhile, drivers in Oklahoma pay just $3.98, Mississippi $4.00, and Louisiana $4.02. That $2.18 difference between California and Oklahoma makes a significant impact on road trip economics, especially for families willing to adjust their routes to pass through cheaper fuel markets.
Why Are Summer Gas Prices So Much Higher This Year?
The primary culprit is supply disruption. The closure of the Strait of Hormuz—a critical global chokepoint for oil shipments—has reduced the flow of both crude oil and refined petroleum products into the American market. This supply constraint pushes prices higher across the board, and the effect compounds during summer months when demand naturally increases as more families hit the road and refineries conduct maintenance shutdowns. What many drivers don’t realize is that summer gas prices are typically higher than winter prices due to seasonal demand patterns and environmental regulations. Refineries switch to special summer-grade blends that cost more to produce, and the season hasn’t even officially started yet.
When you combine seasonal factors with a genuine supply shortage, the result is a significant price spike that forecasters expect will persist throughout the summer driving season. Some analysts warn that if the Strait of Hormuz situation doesn’t improve, gas could approach or exceed $5 per gallon in certain regions—and national averages could hit $5 in high-cost states like California by July or August. The limitation here is that consumers have little immediate leverage. Prices are determined by global supply and geopolitical events largely outside individual drivers’ control. Filling up in a cheaper state helps on the margin, but if you live in California or another high-cost region, you’re constrained by geography and can’t simply choose to buy cheaper gas consistently. Strategic planning—choosing road trip timing, route, and destinations—becomes essential.
What Will Summer Road Trip Costs Look Like at Current Prices?
The concrete numbers reveal the financial burden. Frommers reports that the average summer vacation now costs $7,249, representing an 11% increase from 2024 and more than double the $3,500 average cost in 2022. That $7,249 figure includes lodging, food, activities, and gas—but the gas component is growing faster than other expense categories. Elliott Report analysis shows that per-mile fuel costs are 20-30% higher in 2026 than they were in summer 2023. Consider a practical example: A family driving from Chicago to the Florida Keys for a two-week vacation covers roughly 2,000 miles round trip. With a vehicle averaging 25 miles per gallon and current gas at $4.55 per gallon, they’ll spend about $364 just on fuel. In summer 2023, that same trip cost $284 in gas—a difference of $80.
Add that to their hotel bills, restaurant meals, attraction tickets, and parking fees, and the financial pressure becomes real. For families on fixed incomes or with limited vacation budgets, a $56-80 increase in gas costs might force them to shorten trips, choose closer destinations, or skip vacations entirely. Regional road trips see smaller but still meaningful impacts. A weekend drive from Denver to Utah’s national parks (roughly 600 miles round trip) costs about $109 in gas at current prices—compared to $84 in 2023. That’s a $25 difference on what might be a $800-1,200 weekend trip, representing a 2-3% increase in total trip cost. For some families, that’s manageable. For others living paycheck to paycheck, it tips the scales toward a staycation.
Where Can Drivers Find the Cheapest Gas for Summer Travel?
Strategic route planning can save substantial money. Drivers in high-price regions should consider filling up before entering California, Washington, or Hawaii if planning travel to those states. Conversely, if you’re driving through Oklahoma, Kansas, or North Dakota, fuel prices are roughly 50-80 cents cheaper per gallon than in the most expensive states. Planning a road trip with strategic fill-ups in lower-cost states can reduce overall fuel expenses by $15-50 depending on trip length and route. Beyond geography, discount stacking offers measurable savings. Grocery store fuel rewards programs (typically 3-10 cents per gallon) combined with 3% cash-back credit cards can reduce your effective price per gallon by $0.40-$0.50 when properly executed.
Over 15 gallons, that’s $6-7.50 per fill-up—not transformative, but meaningful. However, the tradeoff is time: you need to accumulate grocery store rewards before your trip, carry multiple cards, and stay disciplined about tracking which vendor offers the best deal. For road-trippers on tight schedules, the convenience of a single fill-up might outweigh the savings from optimization. The limitation is that these savings are incremental, not transformative. Even with aggressive strategy, you can’t escape the fundamental reality that gas is expensive right now. A family saving $50-75 through smart tactics still faces a $300+ fuel bill for a 1,500-mile road trip, compared to $200-250 two years ago. Cost-saving measures help but don’t eliminate the impact of the underlying price increase.
What’s the Outlook for Gas Prices Through Summer and Fall?
Energy analysts expect prices to remain elevated through the entire summer season and potentially into fall. Current forecasts suggest the national average will hold above $4 per gallon, with the possibility of reaching $5 per gallon in some regions if geopolitical tensions persist. WBKO weather and energy reporting indicates that refineries facing maintenance shutdowns coupled with sustained supply constraints create the conditions for prices to stay high or even climb further. The concerning scenario is if the Strait of Hormuz situation remains unresolved or worsens. That chokepoint handles roughly 20-30% of global oil trade, and prolonged disruptions could push crude prices higher, triggering further increases at the pump.
Even a 20-cent-per-gallon increase would add another $3 to a typical fill-up and extend the financial strain on summer vacation budgets. Conversely, if supply improves faster than expected, drivers might see some relief by late August or September, though experts emphasize this is optimistic and not the base-case scenario. The warning here is clear: families planning summer vacations should build gas prices at $4.50-5.00 per gallon into their budgets, not use the current national average as a baseline. Waiting until June or July to finalize road trip plans risks sticker shock when you fill up. Making decisions now, with current pricing in mind, allows families to choose trips and budgets realistically rather than discovering unaffordable fuel costs mid-vacation.
How Are Families Responding to Higher Road Trip Costs?
Consumer behavior is shifting. Some families are choosing destinations within a 300-500 mile radius rather than cross-country trips. Others are consolidating multiple weekend trips into one longer vacation to reduce total fuel consumption. Travel booking sites report increased interest in flights for longer distances—counterintuitively, airfare plus rental car sometimes rivals the all-driving option when current gas prices are factored in, though this varies by route. A concrete example: A family in Michigan considering a road trip to Maine for a week-long vacation (roughly 2,000 miles round trip) is now comparing costs with flying to Boston and renting a car for local exploration.
At current gas prices and tolls, the all-driving option costs approximately $400-450 in fuel alone. Flying and renting a compact car for one week runs roughly $500-600 total for flights and car rental. For families with time constraints, the tiny cost difference makes flying attractive despite the added airport hassles. For families prioritizing the journey itself and road-trip experience, they’re accepting the higher fuel costs. This economic pressure is genuinely altering vacation patterns.
What Should Drivers Know Before Hitting the Road This Summer?
The fundamental takeaway is that summer 2026 road trips will cost significantly more than recent years due to sustained elevated gas prices. The $1.40-per-gallon year-over-year increase isn’t temporary—energy analysts expect prices to remain high through summer. Families should plan road trips with realistic fuel budgets, consider shorter distances or alternative transportation, and look for strategic cost-saving opportunities through geographic arbitrage and discount stacking.
Looking ahead, gas prices have become a major factor in summer vacation planning that rivals lodging and food costs for many families. While we can’t control global oil markets or geopolitical events, we can control our decisions about trip length, route, timing, and vehicle efficiency. Families taking these factors seriously before booking trips can reduce financial strain and make more informed choices about how to spend vacation time and money.
Conclusion
Summer road trips in 2026 will be more expensive than in recent years, driven by gas prices that sit $1.40 higher than a year ago and represent a 53% increase since February. The national average of $4.55 per gallon is expected to hold steady or climb further through the summer season, with some regions already paying over $6 per gallon. When you add gas costs to lodging, food, and activities, the average family vacation now tops $7,249—up 11% from 2024 alone.
Families planning summer travel should adjust budgets upward, consider destinations within 300-500 miles to reduce fuel costs, and pursue cost-saving opportunities through geographic arbitrage and discount programs. The good news is that awareness of these costs, combined with strategic planning, allows you to make informed decisions about vacation trade-offs. The hard reality is that external factors—global oil supply, geopolitical events, and seasonal demand patterns—mean we have limited control over gas prices themselves. Plan accordingly, and make choices that align with your family’s priorities and budget.
