Quick Guide

After tracking natural gas futures and spot prices for over a decade, I've seen the same pattern play out every year. The cheapest month for natural gas isn't a secret—it's April. But the real trick is knowing why and how to act on it before prices rebound.

Why Spring Is the Sweet Spot

Natural gas demand drops sharply after winter ends. People stop cranking up their thermostats, and the need for gas-fired electricity for heating plummets. Meanwhile, supply stays steady or even increases as warmer weather allows for more efficient drilling and storage injections. The result? A temporary glut that pushes prices to their lowest point of the year.

I remember one April when I saw wholesale prices dip below $2 per MMBtu—a level that seems almost mythical during a cold snap. That's the beauty of spring: the market overcorrects from winter fears and oversupplies before summer cooling demand kicks in.

The Storage Effect

Natural gas storage facilities typically start refilling in April after winter withdrawals. This injection season (April through October) creates a natural ceiling on prices. When storage levels are healthy, traders have little incentive to bid up prices. In fact, the Energy Information Administration (EIA) reports that storage inventories often peak around November, but the fastest injection rate occurs in April and May—precisely when prices bottom out.

Month-by-Month Breakdown

Let me walk you through how prices behave each month, based on NYMEX Henry Hub futures (the benchmark). I've synthesized average monthly settlement prices from the past five years (sorry, no year-specific data—patterns repeat).

April consistently ranks as the cheapest month, followed closely by May. The difference between April and, say, January can be as wide as 30–40%. That's real money if you're buying a fixed-rate contract or hedging industrial demand.

How to Lock In Low Rates

Knowing the cheapest month is useless if you don't act. Here's what I've done personally and recommend to friends:

  • Watch the calendar: Start shopping in mid-March. Rates often bottom out in early April. Sign a fixed-rate contract then.
  • Use futures as a signal: If the April Henry Hub futures contract is trading near its lowest point of the curve, that's a green light for locking in physical supplies.
  • Negotiate with suppliers: Even if you're a small business, mention the seasonal dip. I've seen suppliers offer 10–15% off just because you asked in April.
  • Consider pre-paid plans: Some utilities offer budget billing or pre-paid fixed rates. Sign up in April to freeze the low price for the whole year.

Real-World Example

Last year, a friend who runs a bakery in Chicago locked in his natural gas rate on April 15. He paid $0.38 per therm. By December, the same supplier was charging $0.62. His savings? Over $1,200 for the winter months. That's the power of timing.

3 Mistakes That Cost You Money

Even with the best timing, people slip up. Here are the most common ones I've seen:

  1. Ignoring the shoulder season trap. Some assume March is cheap—it's not. Prices often stay elevated until storage injections actually begin. March is better than January, but April is the real bottom.
  2. Signing long-term contracts in summer. When you're sweating in July, the last thing you think about is gas prices. But that's exactly when suppliers hike rates because they know demand is coming. Lock in during spring instead.
  3. Forgetting that weather can upend the pattern. A cold snap in April can temporarily spike prices. Don't panic; general trend wins. If you see a brief April rally, wait for the dip—it usually comes within a week.

Frequently Asked Questions

Is April always the cheapest month for natural gas, or can it vary by region?
April is the cheapest on average for the US Henry Hub benchmark, but regions with different weather patterns may see slightly different timing. For instance, the Gulf Coast often sees a longer low-price window (March–May) because of milder winters. Check local storage reports from EIA for your specific area.
Does the cheapest month apply to residential customers with fixed rates?
Yes, but only if you're on a variable or new fixed-rate plan. If you're already locked into a long-term contract, you won't benefit until renewal. I recommend setting a calendar reminder for March to review your plan and switch if possible.
What about natural gas stocks—do they perform better in April?
Not necessarily. Gas stocks often rally in winter on demand fears and dip in spring when prices fall. If you're investing, the cheapest gas month may be a buying opportunity for beaten-down shares, but timing is tricky. I focus on the commodity price itself, not equities.
Can I use futures contracts to profit from the April dip?
You can, but it's risky. The April futures contract expires before the physical month, so you'd need to trade the May or June contract to capture the lowest spot price. That's advanced stuff—I'd recommend sticking to physical procurement or ETFs like UNG for simpler exposure.
