Yes, Memorial Day could trigger meaningfully higher gas prices. GasBuddy analysts forecast that the national average gasoline price could reach $5.00 per gallon by the end of May 2026, coinciding with the holiday travel period. As of May 7-8, 2026, the national average for regular unleaded sits at $4.55 per gallon—already 25 cents higher than the previous week and $1.40 above where prices stood in May 2025. With the summer driving season ramping up and geopolitical tensions continuing to roil crude oil markets, the trajectory points upward during the final weeks of May.
The combination of seasonal demand and unresolved supply uncertainty creates a perfect storm. Families planning Memorial Day weekend road trips face the prospect of paying significantly more at the pump than they did a year ago. Some regional markets are already approaching that $5.00 threshold. California’s average has reached $6.16 per gallon, Washington state $5.76, and Hawaii $5.66. These aren’t speculative; they’re live prices that Americans are paying today.

When Will Gas Prices Peak Around Memorial Day?
The specific timing matters because memorial day falls on May 26, 2026—right in the middle of the window when analysts expect prices to test $5.00 or potentially exceed it. gasBuddy’s forecast suggests the peak could arrive by late May, precisely when millions of Americans hit the road. The energy forecasters at the Energy Information Administration (EIA) project that the monthly average peaked around $4.30 per gallon in April, but that was a monthly average. Daily prices have climbed since then, meaning the week of Memorial Day could see spot prices materially higher than that April average.
Moody’s Analytics economist Mark Zandi takes a longer view, predicting that gas prices will settle around $3.50 per gallon by the end of 2026. That would represent a roughly 50-cent premium over pre-conflict levels, suggesting the current spike is temporary relative to the year as a whole. However, “temporary” doesn’t help the driver filling up on May 24th for a holiday road trip. The distinction between annual averages and daily prices is critical: the yearly forecast offers little consolation to someone paying $5 per gallon in the moment.
Why Geopolitical Tensions Are Driving the Memorial Day Price Surge
The Iran conflict that escalated in late February 2026 injected roughly $1.50 per gallon of geopolitical risk premium into crude oil prices. The Strait of Hormuz, through which roughly one-third of seaborne traded oil flows, suddenly became a focal point of concern. When tensions spiked, markets repriced immediately. Even partial announcements about reopening shipping lanes triggered rapid reversals, demonstrating how sensitive oil markets are to Middle East developments. The limitation of this analysis is that geopolitical risk is inherently unpredictable.
No analyst can forecast when a new incident might occur or when tensions might de-escalate. This volatility extends the range of possible outcomes. GasBuddy warns that prices could reach $6 per gallon later in the summer if tensions escalate further or supply disruptions materialize. Conversely, if Middle East tensions ease unexpectedly, prices could fall sharply. Consumers planning travel shouldn’t assume the worst case, but they should recognize that upside surprises remain possible.
Which Regions Will See the Worst Memorial Day Pump Prices?
The West Coast and Hawaii face structurally higher prices that will likely persist through Memorial Day. California’s $6.16 average reflects state fuel blends, refinery constraints, and carbon pricing mechanisms. Washington at $5.76 and Oregon at $5.34 similarly reflect West Coast-specific factors. For a family in California planning a 500-mile drive over Memorial Day weekend, the cost difference compared to the national average adds up quickly.
A car with a 15-gallon tank would cost roughly $90 to fill in California versus $68 at the national average—a $22 difference per fill-up. Illinois stands as the only Midwest state currently above $4.99 per gallon, while most other states cluster in the $4.40 to $4.70 range. Regional variation matters because it affects where Americans choose to travel and how they budget. A family living on the East Coast will face lower prices than their West Coast counterparts, but “lower” is still relative—even regional lows remain elevated compared to historical norms.
How Households Should Budget for Memorial Day Travel
The immediate calculation is straightforward: take your planned mileage, divide by your vehicle’s fuel economy, and multiply by the current regional gas price. A household driving 800 miles roundtrip in a 28-mpg sedan would need roughly 29 gallons at $4.55 per gallon, totaling $132. Compare that to the same trip at last year’s prices around $3.15 per gallon, which would have cost $91—a $41 difference on fuel alone. For families in California, that same trip could cost $178, a $87 swing compared to 2025.
The tradeoff is immediate: delay the trip to June if possible when prices may moderate slightly, shift to a long weekend in early May, or adjust the destination to reduce mileage. Some households may choose to skip Memorial Day travel altogether and revisit these plans for July Fourth or summer vacation. Others can absorb the cost and proceed as planned. The point is to calculate the actual impact on household budget rather than abstractly knowing prices are high.
The Uncertainty Ahead: Why Prices Could Spike Further
GasBuddy’s warning about potential $6 per gallon prices later in summer reflects genuine supply chain risks. If the Iran conflict escalates or if a new disruption occurs—a refinery outage, hurricane damage to Gulf production, or a shipping incident in the Strait of Hormuz—crude oil prices would spike immediately. Gasoline prices at the pump typically lag crude moves by a few days, but the speed and magnitude of adjustment can be dramatic. A $10 per barrel jump in crude translates roughly to 25 cents per gallon at the pump.
The limitation of forward guidance is that it cannot account for surprises. The EIA’s baseline forecast assumes no major supply disruptions beyond what’s already priced in. Real-world geopolitical events don’t respect forecasts. Consumers should recognize that $5 may not be the ceiling, and planning should include some buffer for higher-than-expected prices rather than assuming GasBuddy’s $5 prediction represents a hard cap.
What the Annual Outlook Means for Summer Driving
The EIA projects that 2026 will average above $3.70 per gallon for the year, with the spike concentrated in the spring and early summer. That average already incorporates the Iran-driven premium. By October or November, if geopolitical tensions normalize, prices could fall noticeably.
A family considering multiple summer trips might prioritize the heaviest-mileage journey for late August or September when seasonal demand begins to ease and any geopolitical premium may have begun to fade. The trade-off is accepting the weather constraints of later-summer travel versus accepting higher fuel costs now. Some families have flexibility; others don’t. But understanding the annual pattern—that summer 2026 is likely to be expensive, but fall may offer relief—helps contextualize the Memorial Day spike as a peak rather than a permanent new normal.
Looking Past Memorial Day: Summer 2026 Fuel Outlook
Memorial Day is not the end of the story; it’s the beginning of peak summer demand season. June and July typically see the highest seasonal fuel consumption as families take vacation trips. If geopolitical risk remains elevated through June, prices could sustain near the $5 level or higher.
The seasonal demand curve typically peaks in early summer and begins declining in mid-August. The forward-looking insight is that households should view Memorial Day as a preview of conditions likely to persist through July. By August, if no new geopolitical shocks occur, prices may begin moderating as seasonal demand curves start declining. Moody’s forecast of ~$3.50 by year-end implies a significant decline from current levels, but that decline would likely begin in the late summer or early fall rather than immediately after Memorial Day.
Conclusion
Memorial Day 2026 will likely see gas prices at or near $5 per gallon across much of the country, driven by the combination of seasonal demand, Iran-related supply concerns, and structural tightness in refining capacity. Families planning holiday travel should budget accordingly, factoring in current regional prices rather than historical averages. The difference between a family in the Midwest and one in California could easily be $50 or more on fuel costs for the same trip.
The broader reality is that 2026 fuel costs remain elevated compared to 2025, but this elevation is temporary in the context of the full year. By fall, prices are expected to moderate toward $3.50 per gallon if geopolitical conditions stabilize. For now, households should plan, compare prices across potential travel dates and routes, and recognize that Memorial Day represents a peak rather than a permanent regime shift.
