Yes, gas prices will almost certainly be higher this summer compared to last year. As of May 7, 2026, the national average for regular gasoline stands at $4.55 per gallon—a 66.71 percent increase compared to May 2025. For a typical family planning a summer road trip, this translates to roughly $876 more in fuel costs if prices remain elevated through the season. The price surge has been sharp and sustained: gasoline is up 17.34 percent in just the past month alone, with wholesale prices jumping 1.88 percent on a single day (May 8) to reach $3.52 per gallon.
The core driver behind these increases is not seasonal demand patterns or refinery maintenance. Instead, a geopolitical crisis is directly responsible. The disruption of the Strait of Hormuz—a vital shipping lane carrying roughly 20 million barrels per day of oil and refined fuels—has created a global supply shock that has rippled through American gas stations. This is not speculation about future costs; it is a present reality already reflected in the prices consumers face at the pump.

What Are Gas Prices Doing Right Now in May 2026?
The national average for regular gasoline is $4.55 per gallon as of May 7, 2026. This figure masks enormous regional variation. In California, drivers are paying $6.16 per gallon, while consumers in Oklahoma enjoy prices as low as $3.98 per gallon—a spread of over $2 per gallon for the same fuel. Washington state residents face $5.76 per gallon, and Hawaii drivers contend with $5.66 per gallon. On the opposite end, Mississippi ($4.00), Louisiana ($4.02), and Arkansas ($4.02) offer the lowest prices outside of Oklahoma and Nebraska ($4.08).
These price differences matter enormously for household budgets. A California driver with a 14-gallon fuel tank will pay about $86 to fill up at $6.16 per gallon. That same tank costs just $55.72 in Oklahoma. Over a summer of weekly fill-ups, the difference reaches $1,600 or more depending on location. For vacation planning, this means that a family in a high-price state faces a genuine financial penalty simply for living in or traveling through expensive regions, while families in lower-price regions enjoy relative relief from fuel costs.
Regional Price Variations: Why Does Your State Matter?
The five most expensive states for gasoline—California, Washington, Hawaii, Oregon, and Nevada—all share certain characteristics. These are typically west coast states with unique fuel formulations mandated by environmental regulations, limited refining capacity, and long supply chains that create logistical costs. California’s price of $6.16 per gallon is particularly notable because it reflects both these structural factors and the impact of state-level fuel taxes and environmental standards.
However, there is an important limitation to consider: even in low-price states like Oklahoma and Mississippi, prices have still increased significantly compared to a year ago. The national trend of rising fuel costs affects virtually every market, though the regional variations determine whether drivers face moderate or severe increases. A Mississippi driver enjoying the nation’s second-lowest prices at $4.00 per gallon is still paying substantially more than they did in May 2025. The location advantage is real, but it does not insulate anyone from the underlying global supply shock driving prices upward across the board.
The Summer Vacation Impact: How Much More Will You Pay?
For a typical American family planning summer vacation road trips, the math is unforgiving. The Energy Information Administration (EIA) projects an average price of $4.16 per gallon for Q2 (April through June) and $3.91 per gallon for Q3 (July through September). While Q3 shows a modest decline from Q2 levels, both figures substantially exceed historical norms and guarantee elevated fuel costs throughout the vacation season. Consider a concrete example: a family of four taking a 2,000-mile summer road trip in a vehicle that gets 25 miles per gallon would need 80 gallons of fuel.
At the projected Q3 average of $3.91 per gallon, that trip costs $313 in fuel alone. Five years ago, the same trip might have cost $150 to $180 depending on the year. The $876 figure cited for typical car owners reflects not just a single vacation but the cumulative impact of higher prices across the entire summer season and all driving activities—commuting, weekend trips, and vacation travel combined. This cost increase hits households with lower incomes and those without the flexibility to reduce driving most severely.
Summer 2026 Fuel Cost Forecast: What to Expect from June Through September
The EIA’s official Short-Term Energy Outlook projects that gasoline will average $4.16 per gallon in Q2 and decline slightly to $3.91 per gallon in Q3. For the full year 2026, retail gasoline prices are forecasted to average more than $3.70 per gallon—well above historical averages from the 2010s and comparable to elevated price periods during previous global crises. The projection includes an assumption that supply disruptions ease somewhat during Q3, which explains the anticipated price decline from Q2 to Q3, but this improvement remains relative to Q2’s higher levels. The limitation to keep in mind is that these forecasts are based on current geopolitical conditions and assumptions about how long supply disruptions will persist.
If tensions escalate further or if new disruptions emerge, prices could remain higher than projected. Conversely, if diplomatic resolution occurs earlier than expected, prices could fall more sharply. The EIA forecasts represent the agency’s best assessment given available information, but they are not guarantees. Families planning summer budgets should assume gas prices will remain elevated throughout the vacation season and build financial contingency into their plans.
The Root Cause: Geopolitical Tensions and the Strait of Hormuz Disruption
The Strait of Hormuz, a narrow waterway between Iran and Oman, is one of the world’s most critical energy chokepoints. Roughly 20 million barrels per day of oil and refined fuels—approximately 20 percent of global supply—flows through this passage. Since early March 2026, this traffic has been suspended due to US-Iran conflict, creating a supply shock that has reverberated through global energy markets and directly into American gas prices. This is not a temporary disruption or routine maintenance.
The suspension reflects active geopolitical conflict, and the timeline for resolution remains uncertain. As long as the Strait remains disrupted, the supply shortage will continue exerting upward pressure on global oil prices, which directly translates to higher gasoline prices at US pumps. The warning here is clear: this price pressure will persist as long as the underlying geopolitical conflict remains unresolved. No amount of domestic policy change or refinery adjustments can offset the impact of 20 million barrels per day in disrupted supplies when that volume represents such a large share of global consumption.
What Drivers Should Know About Managing Fuel Costs This Summer
Individual consumers have limited ability to influence wholesale gasoline prices or geopolitical events. However, several practical steps can reduce the impact of elevated fuel costs. Consolidating trips to reduce total driving, properly maintaining vehicle tire pressure (which improves fuel efficiency by 3 to 5 percent), and avoiding aggressive acceleration all contribute to better fuel economy. For drivers in high-price states like California or Washington, filling up near state borders or planning purchases to coincide with price dips offers modest savings.
The comparison with previous high-price periods is instructive. During the 2008 energy crisis, American households responded by reducing driving and shifting consumption patterns. Current prices, while elevated, have not yet reached the absolute peaks seen in 2008 when inflation-adjusted prices exceeded $5 per gallon nationally. This suggests that while the current situation creates genuine financial strain, especially for lower-income households, it falls short of the most severe historical episodes. However, the uncertainty about how long geopolitical disruptions will persist means households should prepare for sustained elevated prices rather than expecting rapid declines.
Looking Ahead: Summer 2026 and Beyond
The EIA’s forecast of $3.91 per gallon for Q3 (July-September) reflects an assumption that supply disruptions may ease somewhat during the summer months, potentially through diplomatic channels or altered shipping patterns. However, this modest improvement should not be mistaken for a return to historical price levels. Even the projected $3.91 average for Q3 remains substantially above the $2 to $3 range that characterized much of the 2010s and early 2020s.
For the remainder of 2026 and potentially into 2027, gasoline prices will likely remain elevated by historical standards. The full-year forecast of more than $3.70 per gallon reflects this persistent pressure. Families planning extended summer travel should budget accordingly, understand regional price variations, and recognize that relief is unlikely to arrive quickly. The underlying cause—geopolitical disruption of critical energy supply routes—will not resolve on a schedule convenient for vacation planning.
Conclusion
Gas prices will be significantly higher this summer compared to 2025. The national average of $4.55 per gallon as of May 2026 represents a 66.71 percent increase over the prior year, and projections for Q3 average $3.91 per gallon. Regional variations are dramatic, with California drivers paying $6.16 per gallon while Oklahoma drivers pay $3.98 per gallon, but no region escapes the upward pressure created by global supply disruptions. For a typical family, this means roughly $876 additional fuel costs across the summer vacation season if prices remain elevated—a meaningful increase in household expenses.
The root cause is the disruption of the Strait of Hormuz since early March 2026, which has halted the flow of roughly 20 million barrels per day of global oil supply. Until this geopolitical conflict resolves, American consumers will face elevated gasoline prices at the pump. Families should budget for sustained higher fuel costs throughout the summer and fall, plan road trips strategically, and understand that relief is unlikely to arrive quickly. The EIA’s official forecasts provide the most reliable guidance available, but they assume conditions that may or may not hold as events unfold.
