Where the data comes from

Every figure on the site traces back to one of these.

  • Storage. EIA’s Weekly Natural Gas Storage Report, the official Thursday figure, and a daily storage estimate between prints.
  • Supply and demand. Daily dry-gas production, LNG feedgas, pipeline flows to Canada and Mexico, and demand by sector (including power burn), as daily estimates. Report-day demand and power burn are early readings, usually revised the next day.
  • Weather. Degree days computed from seven weather models (GFS, ECMWF, ECMWF AIFS, AIGFS, GEFS, AIFS Ens Mean and CFS) against NOAA NCEI 1991–2020 normals, base 65°F.
  • Prices. NYMEX natural gas futures (delayed quotes) for the front month and the curve; Dutch TTF, UK NBP and Asian JKM for the international comparison, shown in $/MMBtu.
  • Weekly commentary. The week’s seven daily outlooks and the week’s public market news.

When things are published

The Daily Report
Every day of the week. Since 10 Jul the median weekday report was published at 09:22 ET (55 of 64 by 10:30 ET) and the median weekend report at 12:40 ET. A report waits until all ten core data series for the gas day are in, rather than publish blanks.
EIA storage report
Thursdays 10:30 ET (holiday weeks shift).
Weekly commentary
Sunday morning (US time).
Degree days
Model runs land through the day: GFS, ECMWF AIFS, AIGFS, GEFS and AIFS Ens Mean four times a day, ECMWF twice, CFS once.

A Discord alert goes to members as each daily report is published. The site keeps the last 30 daily reports and 90 days of degree-day pages.

The storage estimate

Two kinds of storage figure appear on the site, and each one is labelled so you can tell them apart:

EIA official · week ending 25 Sep
The weekly storage number EIA publishes on Thursday at 10:30 ET. The report compares it with EIA’s 5-year average for the same week.
Daily estimate · 7 Oct
A daily estimate of storage between EIA prints (not our weekly EIA estimate in section 02). The report day is an intraday reading; the day before it is settled.

Each Daily Report carries our estimate of the next eight EIA weekly changes, and a projection to the end of the season. The track record below scores the estimate in the last report published before each Thursday print.

Track record

Over the last 16 EIA prints (weeks ending 12 Jun to 25 Sep), our estimate missed by 6.4 Bcf on average. It was within ±10 Bcf on 13 of them, and the worst miss was 13 Bcf. Using the EIA 5-year average change as the estimate would have missed by 12.6 Bcf on average.

Net change, Bcf. EIA prints at 10:30 ET. Miss = our estimate minus EIA’s print; misses larger than 10 Bcf are in bold. Our estimate is the one in the last report published before each print. The benchmark is the EIA 5-year average change, not an analyst consensus.

The outlook

Every Daily Report opens with a call for three horizons: the next 1–3, 3–6 and 6–12 months.

Call
The report’s direction for a time window: Bullish (prices likely to rise), Bearish (likely to fall) or Neutral.
Strength
How strongly the call is held, 40 to 85: 40–50 a lean, 50–65 a clear call, 65–85 high conviction. A Neutral call can still lean one way, shown as “Neutral, leaning bearish”.

The outlook is written every day from that day’s data: the day’s data first, then a check against the previous day’s calls, noting what changed since yesterday. A call is listed as changed only when its direction flips or its strength moves into another band.

The weekly commentary is written each Sunday from the week’s seven daily outlooks and the week’s public market news. It uses five direction words per horizon: Pressuring and Cautious lean lower, Balanced is neutral, Supportive and Constructive lean higher. A Bullish daily call maps to Supportive or Constructive, Neutral to Balanced and Bearish to Cautious or Pressuring.

Nothing on the site is financial advice. Trading natural gas futures involves substantial risk.

Reading the report

Three things are drawn the same way wherever they appear: the outlook calls, the colours on the changes and the lines on the charts. Each report’s How to read button explains them again with that day’s figures.

How the outlook calls are drawn

Each window has a track from bearish on the left to bullish on the right, and the filled marker is the call. A Neutral call sits in the grey middle third (in its centre, or halfway out to that third’s edge when it leans one way); a Bearish or Bullish call starts at that edge at strength 40 and reaches the end of the track at 85, with ticks at 50 and 65 where it becomes a clear call and then high conviction.

Example · the free sample, Wed 30 Sep

Open it
Next 1–3 months, September to December 2026: Bearish, strength 55, a clear call. Unchanged since the last report.
Next 3–6 months, December 2026 to March 2027: Bearish, strength 40, a lean. Less bearish −17, was 57, a clear call.
Next 6–12 months, March to September 2027: Neutral, strength 45, leaning bearish. Unchanged since the last report.

Bearish = prices more likely to fall than rise over that window; Bullish = more likely to rise. The further from the centre, the stronger the call: 40–50 lean · 50–65 clear call · 65–85 high conviction (Bearish and Bullish calls). A Neutral call sits in the middle; its word says whether it leans. Hollow ring = the Tue 29 Sep report; the arrow shows which way the call moved.Bearish = prices more likely to fall; Bullish = rise. Further from centre = stronger (40–85). Hollow ring = Tue 29 Sep.

Reading the colours

Colour = what it usually means for pricesColour = which way it movedSupportiveUpPressuringDownSmall move

Arrows show which way each number moved. Green means the move usually supports natural-gas prices; red means it usually weighs on them. More production is red because extra supply tends to push prices down. More LNG feedgas is green because exports take gas out of the US market. Storage is judged against the 5-year average for the same date, so a normal-sized build stays grey. Grey means the figure is smaller than half its usual size over the past year (for a day change, half the usual daily move). It’s a rule of thumb, not a forecast: the outlook weighs everything together. Degree days keep their warm and cool words; the number is coloured by what it means for prices, except on the Degree Days pages, where word and number both keep the temperature colour.

Lines on the charts

Every chart draws the same kinds of line in the same way, in the dark and the light report alike. The normal is always the dotted line, with its value and name at the right-hand end: the 5-year average for storage, the 30-day average for daily flows and the 1991–2020 normal for degree days.

Measured Solid line in the measure’s colour: what actually happened.
Normal Dotted line, labelled at the right: the yardstick (5-yr average, 30-day average, 1991–2020 normal).
Projected Dashed line in the measure’s colour: our projection, not a reading.
Comparison Thin grey line: another period for context (a year ago, last week’s settle).
Smoothed Faint line in the measure’s colour: its own 5- or 7-day average.
Above / below normal Tint above the dotted line, hatch below. Only where the gap to a true normal is the story.

Degree days

Degree days per station (base 65°F) from ~300 airport stations, weighted by population or by gas-heating homes, for the nation and the five EIA storage regions. Normals: NOAA NCEI 1991–2020. Trends compare the same target dates with the run 12 or 24 hours earlier (dates both runs cover).

Regions
National, East, Midwest, South Central, Mountain, Pacific (the five EIA storage regions and the nation).
Weighting
Population-weighted: degree days averaged by where people live. Gas-weighted: degree days averaged by where homes heat with gas.
Forecast length
15 days ahead from each run (14 for the ECMWF family, whose files start later in the day).
Wording
Against normal, the viewer says “warmer than normal” or “colder than normal” from the temperatures behind the degree days, so the word always matches the weather.

Contango
Later months priced above the front month.
Call
The report’s direction for a time window: Bullish (prices likely to rise), Bearish (likely to fall) or Neutral.

HDD / CDD
Heating / cooling degree days: how far the day’s average temperature is below / above 65°F. More degree days = more weather-driven gas demand.
TDD
Total degree days, HDD + CDD.

Surplus / deficit (to the 5-yr)
How far storage is above / below the 5-year average for the same date.
End of season
The last EIA week of injection season (end of October) or withdrawal season (end of March); the level then is watched as the winter or summer starting point.
Balance
Supply minus demand. Positive means gas is going into storage; over the past year it has moved with the daily storage change (correlation 0.96 over 300 settled days), though a single day can differ by a few Bcf/d.

Polar vortex
A pool of very cold air over the Arctic. When it weakens or splits, cold outbreaks can reach the US and lift heating demand sharply.
Force majeure
An outage declared beyond an operator’s control, e.g. a pipeline shutting a section; it suspends delivery obligations.
Netback
What an LNG cargo earns after shipping and regasification costs; it shows whether exporting pays.
