We cannot predict San Diego’s gas prices for May 14, as that date is four days beyond today’s report. However, as of early May 2026, San Diego County’s average gas price stands at $6.141 per gallon for self-serve regular—the highest level since October 4, 2023. If current price trends continue, drivers should expect to pay roughly this amount or higher at the pump on May 14, though geopolitical developments in the Strait of Hormuz could shift prices in either direction.
For context, a single week saw prices jump 16 cents, so volatility remains high. The San Diego area ranks 10th highest in California for gas prices, reflecting both state-wide supply constraints and regional refining capacity limits. Drivers filling a 15-gallon tank today pay approximately $92 before taxes, compared to $77.40 a year ago—a difference of nearly $15 per fill-up driven by crude oil disruptions affecting the state’s refineries.

What Are San Diego’s Current Gas Prices?
San Diego County’s average gas price as of May 3, 2026 was $6.141 per gallon, marking the highest price since early October 2023. This represents the reality facing local drivers—not a prediction, but today’s cost at the pump. Rankings within California show San Diego holding the 10th position among the state’s regions, trailing only areas like the San Francisco Bay Area and Los Angeles County, where prices hover slightly higher. The variance across California ranges from $5.97 to $6.30 per gallon depending on local refining infrastructure and proximity to supply terminals. Price volatility has been dramatic.
Overnight, prices jumped 3 cents. Over one week, the increase reached 16 cents per gallon. Over one month, drivers saw a 21-cent climb. This acceleration reflects immediate supply concerns rather than gradual market movements. A driver who filled up on April 3 paid roughly $5.93 per gallon; by May 3, that same fill-up cost $6.14—an increase of over $3 per tank for typical vehicles.

Why Are San Diego Gas Prices Soaring?
The primary culprit is turmoil in the Strait of Hormuz, which disrupted crude oil shipments destined for California refineries. California depends heavily on crude imports from the Middle East and other overseas sources, as in-state production has declined significantly. When the Strait of Hormuz experiences supply disruptions, the effect reaches California’s pumps within days, not weeks. The last oil shipment from the region to arrive before the crisis had already been accounted for in recent pricing, meaning further tightening is expected if disruptions persist. California’s refining infrastructure exacerbates this vulnerability.
The state has limited refining capacity relative to demand and has closed several refineries in recent years. Unlike Texas or the Gulf Coast, California cannot quickly substitute supply from other U.S. regions due to strict environmental regulations that require special fuel blends. This regulatory framework, while designed to reduce emissions, limits flexibility during supply emergencies. A refinery outage in the Bay Area or los angeles directly impacts San Diego’s prices because crude must flow through existing pipelines.
How Does San Diego Compare to the Rest of California?
The California state average stands at $6.06 per gallon—the highest level since July 2022. San Diego, at $6.141, exceeds this average by about 8 cents. Los Angeles and the Bay Area rank higher, with some urban areas approaching $6.30. Rural and inland regions like Bakersfield or the Central Valley see prices in the $5.97 to $6.05 range, reflecting lower transportation costs from refineries and different supply logistics.
The 30-cent spread between California’s cheapest and most expensive regions illustrates how local geography and refining proximity matter. San Diego’s position as the 10th highest in California reflects its size, fuel demand, and distance from major refineries. The city’s population of 1.4 million requires constant fuel supply, competing with San Francisco, Los Angeles, and Sacramento for limited crude inventory. Winter blend fuel in cooler months would bring slightly lower prices, but we are heading into summer blend season, which costs more to produce and purchase due to stricter volatility standards.

What’s Driving the Broader Price Surge?
Geopolitical instability in the Strait of Hormuz—a chokepoint through which roughly 20 percent of global crude oil passes—has created immediate market anxiety. Even before disruptions fully materialize, traders and refiners adjust prices upward as a risk premium. Refineries that typically schedule six-week-ahead purchases now face uncertainty: Will the next tanker arrive on time? Will shipping costs spike? This uncertainty translates to higher prices at the pump today.
Crude oil futures markets reflect this anxiety directly. When Hormuz tensions spike, West Texas Intermediate (WTI) crude jumps, and California crude—which trades at a premium to WTI due to its special grade requirements—spikes even more sharply. A $2 increase in crude translates to roughly 5-6 cents per gallon at retail pumps after processing, distribution, and retailer margin. The year-over-year increase of $1.44 per gallon is largely attributable to crude price movements rather than local factors like taxes or retail markup changes.
How Severe Is This Price Spike Historically?
The $6.141 average marks a significant spike but not an all-time record for San Diego. In 2022, during the global energy crisis following Russia’s invasion of Ukraine, California saw peak prices above $6.40 in some regions. However, hitting $6.14 in May 2026 is notable because it is among the highest levels in recent years, and it arrived faster than expected. Drivers in 2022 saw prices climb gradually over months; in 2026, the climb accelerated in weeks, leaving less time to adjust consumption or plan expenses.
One limitation of current pricing data is that it is based on surveys of major chains and independents, which may not capture all retail stations. Some discount stations or remote locations may offer prices 10-20 cents lower, but availability is limited. Conversely, premium brands or convenience stores in high-traffic areas may charge 10-15 cents more. Budget-conscious drivers must actively seek out competitive pricing, as the “average” obscures meaningful variation. Additionally, wholesale prices can shift daily, so prices posted today may differ by evening.

Year-Over-Year Price Comparison
A year ago, in May 2025, San Diego’s average gas price was approximately $4.70 per gallon—making today’s $6.141 a stunning $1.44 increase year-over-year. In practical terms, a 15-gallon fill-up cost roughly $70.50 in May 2025 and now costs $92.12—an extra $21.62 per tank.
For drivers commuting 30 miles daily in a vehicle averaging 25 miles per gallon, the annual fuel cost difference is approximately $2,640 per year, assuming no reduction in driving. This comparison illustrates why the price surge has become a major issue for families and small business owners dependent on fuel expenses.
What’s the Outlook for May 14 and Beyond?
Predicting exact prices for May 14 remains impossible without knowing whether Strait of Hormuz disruptions resolve or escalate. If calm returns, expect gradual price declines of 5-10 cents per week as refinery confidence increases. If disruptions persist or worsen, prices may climb another 10-15 cents toward $6.30 by mid-May. Historical patterns suggest California prices peak in late May or early June when summer blend production fully transitions, so the timing of any resolution matters significantly.
Longer-term relief depends on either stabilizing the global crude market or increasing U.S. crude production from domestic sources that meet California’s special fuel requirements. Policy discussions around fuel standards, refinery capacity, and emergency reserves continue, but these are political and regulatory debates unlikely to influence prices in the near term. Drivers should prepare for sustained prices in the $5.95-$6.25 range through summer unless major supply disruptions resolve or new production comes online.
Conclusion
San Diego gas prices as of early May 2026 stand at $6.141 per gallon, driven primarily by crude oil supply disruptions in the Strait of Hormuz and California’s limited refining flexibility. While we cannot predict May 14 prices precisely, current trends suggest drivers should budget for prices at or slightly above current levels unless geopolitical conditions shift. The year-over-year increase of $1.44 per gallon represents a real burden for household budgets and business operations, with no immediate policy solutions in place.
Drivers seeking relief should monitor geopolitical news about the Strait of Hormuz, consider fuel efficiency strategies, and explore gas price apps that identify the cheapest stations in their area. In the short term, expect volatility to continue as global energy markets digest supply uncertainty. In the medium term, California’s fuel policies and refining capacity decisions will determine whether prices moderate or remain elevated.
