Disclosure: This is not financial advice. It does not promise a seasonal price.
Introduction
Natural gas seasonality is the habit of reading U.S. storage in two named parts of the year: an injection season and a withdrawal season. The title says prices follow those seasons. A price is a separate quote. This page shows how to label a storage week with the season the Energy Information Administration describes, and how to write a quote beside it without turning the calendar into a forecast.
The weekly series is the EIA Weekly Natural Gas Storage Report. An EIA Today in Energy note describes the withdrawal season as November 1 through March 31 and the injection season as April 1 through October 31: natural gas storage and the seasons. Copy the dates from that note when you use them. Another EIA note says injections can continue past the traditional end of the injection season: injections beyond October. Read it before you treat October 31 as a wall.
Why the year is split
The EIA’s account is about storage, not about a guaranteed price path. Gas is added to underground storage when the weekly report shows an injection. Gas is taken out when the report shows a withdrawal. Heating demand is the reason people talk about winter withdrawals. Power generation is one reason people talk about summer use. Production does not pause because the calendar page turned. Storage is the buffer the report is measuring.
Natural gas seasonality, on this page, means you write the season name next to the week you opened. It does not mean you know the next price.
What to copy from the weekly report
Open the EIA storage page. Write the week ending date. Write the region if you are not using the Lower 48 total. Write the working-gas level as printed. Write the change from the prior week as printed: injection or withdrawal, and the amount only if it is on the page. If the page compares the level with a five-year range, copy that comparison’s words or figures from the page. Do not type a percent from memory.
An EIA Today in Energy article has discussed where inventories stood versus a five-year average at the end of an injection season. If you want that comparison, open the article and cite its date: inventories at the end of an injection season. This page does not restate the figure.
The sheet for natural gas seasonality
- Week-ending date from the EIA report.
- Season label you are using, and the EIA page that defined the dates.
- Lower 48 working gas, or the region, as printed.
- Weekly change: injection or withdrawal, as printed.
- Any five-year comparison, copied, or “not on the page I opened.”
- A futures or spot quote with source and time, or “quote not opened.”
- Weather note with its publisher, or “weather not opened.”
- The sentence you will not add, such as “winter will be higher.”
If the season cell and the storage cell are from different weeks, the sheet is wrong. Natural gas seasonality is a label on a week, not a slogan.
How people connect the seasons to prices
Readers say winter contracts often sit above summer contracts because heating demand is expected. That sentence is a description of a curve you have not opened until you open it. Write the two contract months and the two prices from the screen, with the time. If you did not open the screen, write “curve not opened.” Do not say the premium is large or small without those two numbers.
A storage surprise is the gap between the EIA change and someone else’s estimate. Name the estimator and the date, or do not use the word surprise. The only difference you can compute from EIA alone is this week versus last week, or this week versus the level the EIA table compares it with.
Futures can gain or lose. The CFTC explains the contract: futures market basics. A seasonal label does not change that. Check a firm in NFA BASIC before you pay anyone to trade the quote. Investor.gov is the risk primer. It does not pick a month.
What can make the week look unlike the season name
The EIA notes that injections do not always stop when the traditional injection season ends, and that a hot week can show a withdrawal in summer. So the season name and the weekly sign can disagree. When they disagree, write both. Do not correct the EIA change to match the calendar.
A weather forecast is not the storage report. If you mention a cold snap or a heat wave, name the forecast office and the date. Liquefied natural gas exports, production outages, and power-plant demand are stories. They belong in a note beside the storage row, with a source. They are not a reason to invent a price.
Hurricanes and terminal outages are event notes. Write what the EIA or the operator published. If you only have a social post, it is a clipping. The CFTC warning on internet hype is Understand Risks and Markets before Reacting to Internet Hype.
A weekly routine
On the day the EIA posts the storage report, save the week-ending date and the change. Mark injection season or withdrawal season using the dates in the EIA note, and add “sign disagrees with season” if the change does. Once a month, open two futures months, one in each season, and write both prices or write “not opened.”
Do not buy a winter month because the page says winter exists. The page says the storage calendar has two names. The trade is a different act.
Mistakes
The first mistake is a remembered percent versus the five-year average. Copy it or leave the cell blank.
The second mistake is treating April 1 and November 1 as laws when the weekly sign already disagrees. The EIA has said the boundary is not rigid.
The third mistake is calling a fund’s path the same thing as the storage series. Read the fund document for what it holds. This article does not name a fund.
The fourth mistake is a commission link in place of the EIA table.
The fifth mistake is a health or safety claim. This page is not about home appliances or carbon monoxide. A storage table is not a household instruction.
Regions and revisions
The weekly report is not only a national total. It breaks working gas into regions. If your question is about one region, copy that region’s level and change. Do not answer a regional question with the Lower 48 line. If you do not know which region a headline means, write “region not named.”
The EIA sometimes revises a prior week. When it does, keep the old note and add a revision line with the new date. Overwriting the first number hides the change you would later want to explain. Natural gas seasonality is harder to read if last week’s injection was edited and your sheet still shows the first print.
A model that knows the season is only as good as the files you saved. If the model was not scored on a later winter you already lived through, write “later winter not scored.” A backtest you did not run is not a result.
FAQ
What is natural gas seasonality?
It is the practice of reading EIA storage weeks against the injection season and the withdrawal season the EIA describes.
When are those seasons?
An EIA note describes withdrawal as November 1 through March 31 and injection as April 1 through October 31, and another note says injections can run past that traditional end. Use the notes, not a memory.
Do prices always rise in winter?
This page does not say that. Write the quote you opened. Winter demand can already be in the contract you are looking at.
Where is the weekly number?
On the EIA Weekly Natural Gas Storage Report page.
Is the seasonal label a strategy?
No. It is a label on a table. This is not financial advice.
Conclusion
Natural gas seasonality means naming the injection or withdrawal season beside an EIA storage week. Prices follow that pattern only in the quotes you actually write down. The calendar is not a trade. This is not financial advice.
