When Should I Expect Higher Summer Gas Prices?
Expect higher gas prices from May to September. They peak in July and August. This pattern holds for most drivers, including those in the Detroit area (48202).
Here's what you need to know:
- Summer blend fuel: The EPA requires cleaner gas from June 1 to September 15. It costs more to make. Refineries switch in May, so prices climb early.
- Driving season: More road trips mean higher demand. AAA data shows 70 million Americans hit the road each summer weekend.
- Recent trends: In 2025, national average hit $3.85 in late July. Michigan prices topped $4.10 then, per GasBuddy.
Key Factors Driving Summer Price Spikes
| Factor | Impact | Typical Timing |
|---|---|---|
| Summer blend switch | +20-40 cents/gallon | May-June |
| Memorial Day travel | Demand surge | Late May |
| Peak vacations | Highest demand | July-August |
| Labor Day rush | Final spike | Early September |
