Gas Price Heatmap

Gas price trends over the next 24 hours

When is gas cheapest on Ethereum?

Cheap gas times follow recurring weekly rhythms. Looking at recent data, the lowest-fee windows cluster around:

  • Saturday late night to Sunday morning UTC — usually the week's cheapest stretch.
  • Weeknights 02:00–06:00 UTC — US sleeps, Asia not yet ramped.
  • Sunday evening UTC — pre-Monday lull.
  • Right after spike resolution — base fee falls fast once demand cools.

Why gas prices follow these patterns

Ethereum gas is a market for block space. Three forces shape the weekly pattern:

  • Time zone overlap. Demand peaks when US, EU, and Asia are awake at once. It troughs when most of those regions sleep.
  • DeFi and NFT calendars. Token launches and mints tend to be scheduled mid-week US time, pushing fees up.
  • Base fee inertia. EIP-1559 base fee adjusts every block, but a quiet hour really does mean cheaper transactions.

How to time transactions for cheap gas

  • Read the heatmap, then pick a window. Even a few hours of patience can cut your fee in half.
  • Check the next-best-time card. It surfaces the upcoming window without you having to interpret the heatmap.
  • Set a gas alert. Pick your target Gwei and forget about it. Create an alert.
  • Avoid hype windows. Big mints and token launches can wipe out the savings of a normally-cheap hour.
  • Use Layer 2s for routine activity. If you don't need mainnet settlement, L2 is always cheaper than even the cheapest mainnet hour.

Frequently asked questions

What time is gas cheapest on Ethereum?

Gas is typically cheapest between roughly 00:00–08:00 UTC on weekdays and across most of Saturday and Sunday, when US and European users are off-network. The 7-day heatmap above shows the exact pattern.

What day of the week has the lowest gas fees?

Saturdays are usually the cheapest day on Ethereum, followed by Sundays. Tuesday through Thursday during US market hours tend to be the most expensive.

Are gas fees lower on weekends?

Yes, on average. Weekend trading volume is lower across DeFi and NFTs, base fee tends to drop, and competition for block space eases.

How much can I save by waiting for cheap gas times?

On a typical week, the gap between peak and off-peak gas can be 50–80%. A transaction that costs $25 during US market hours might cost $5–8 the same night.

Why is gas expensive during US market hours?

US users dominate active DeFi and NFT volume. When their day starts, demand for block space rises, base fee climbs, and priority tips inflate to compete.

Does the cheap gas window change week to week?

The shape is stable but the exact low can shift by NFT mints, token launches, or macro news. The live heatmap above reflects the most recent week, not a fixed schedule.
