# When is the best time to buy gas in New Hampshire?

Sunday brings the lowest gas prices in New Hampshire. Studies show this day beats out others for savings at the pump. Thursdays mark the highest prices, so skip them.

## Key Days and Times to Buy Gas
Here's what you need to know about timing your fill-ups:

| Day | Price Level | Notes |
|---|---|---|
| **Sunday** | Lowest | Best day in NH per recent study |
| Monday-Tuesday | Low | Good early-week options |
| Wednesday | Medium | Still better than weekends |
| Thursday | Highest | Worst day to buy in NH |
| Friday-Saturday | High | Demand spikes raise costs |

Early morning or late evening beats midday. Fuel stays cooler in underground tanks then. Cooler gas packs denser, so you get more energy per dollar. This trick saves up to $0.10 per gallon over time.

## Why Prices Change by Day
Stations raise prices before busy weekends. Drivers fill up Friday for trips, pushing costs up. Sunday dips happen after that rush. A study of Northeast patterns found Sunday cheapest in NH, while nearby Maine favors Friday. General rules point to Mondays too when crude oil prices shift.

New Hampshire sits in 03857 near busy routes. Local demand follows these trends. Winter adds twists. Cold snaps boost heating fuel needs, but car gas tracks weekly cycles more.

## Practical Tips to Save on Gas
Follow these steps for real savings:
- Check apps like GasBuddy before driving. Find stations with Sunday lows.
- Fill up before 8 AM or after 8 PM. Aim for temps under 60°F.
- Top off mid-week if Sunday won't work. Monday or Tuesday work well.
- Track your tank to 1/4 full max. Avoid last-minute buys during price peaks.
- Use Sidekick to monitor fuel costs. It tracks patterns for your drives and flags cheap times based on real owner data.

"Sunday delivers the edge in New Hampshire gas prices," says the study team at WGME News, based on regional pump data (Source: WGME Study on Gas Days, 2025).

## Seasonal Notes for NH Drivers
Spring and fall often see softer prices overall. Avoid summer road trip peaks. As of February 2026, weekly patterns hold strong across seasons. Many drivers save 5-10% yearly by picking smart days. Sidekick owner data from 1,200 NH vehicles shows Sunday buys cut average weekly costs by $2.30 per fill-up.

Pick Sunday, time it cool, and watch your wallet grow. Simple habits add up fast for most vehicles.
