Will ample supply keep winter heating demand from lifting natural gas futures? EIA’s October 6 outlook anticipates above-average storage when heating begins.[1]

The October 10–November 24, 2026 seasonal window approaches with gains in all eight selected midterm years. Yet only half the 2016–2025 windows rose, weakening the case for a dependable autumn advance.[5]

Supply meets winter demand

EIA’s September 25 report put June–August 2026 Henry Hub spot gas at $2.93/MMBtu, 6% below summer 2025 despite exceptional heat. Renewable generation, record production and ample inventories limited price pressure; LNG terminal maintenance moderated demand growth.[3]

Its September 1 report nevertheless showed first-half 2026 LNG exports up 23% to 17.4 Bcf/d. The European benchmark chart provides export-demand context.[4]

October’s outlook forecasts October 31 storage of 3,850 Bcf, 2% above the five-year average for the November 1 heating-season start. It assumes nearly unchanged winter heating degree days; prolonged cold could increase withdrawals. Its 2027 Henry Hub spot forecast is $3.16/MMBtu versus $3.48 projected for 2026, down 9%, largely reflecting January 2026’s storm-related price spike.[1]

The selected midterm record

TradeWave’s eight selected midterm-election years spanning 1994–2022 show a 12.08% median full-window long result. That favorable seasonal record concerns futures timing; today’s fundamentals cannot validate its repetition.[5]

A gain can conceal losses

The yearly range chart covers the same seasonal period each year, not entire calendar years. The latest selected example, October 10–November 24, 2022, illustrates the stakes: a 5.79% ending gain accompanied a low 21.21% below the starting price. Those highs and lows reveal neither their order nor peak-to-trough drawdown.[5]

EIA forecasts lower national gas-heating expenditures this winter, but a slight increase in the colder West. Weather remains a regional qualification.[2]

What happened inside each seasonal window

NG: yearly seasonal range. Each year shows the same seasonal period. Bars show the price change at its end. Thin lines show the highest and lowest changes from the starting price during that period. The lines do not tell us which move came first or measure a fall from a peak. They are not suggested stop-loss levels.

Across all years

Broader histories test whether the midterm result travels: success falls from 65.0% across 2006–2025 to 50.0% across 2016–2025. The smaller midterm sample warrants caution, not an election explanation. Those comparisons reuse five and two selected midterm years respectively; all ten recent windows also appear in the longer history, limiting independent confirmation.[5]

Some years appear in more than one group, so agreement is not an independent test. A requested lookback can extend beyond available history; the observed years are listed above. Election-cycle groups use matching phases, not consecutive years. Results follow the direction shown: a positive short result means prices fell. Small samples and different market periods make the comparison less conclusive.

What to inspect next

Recorded prices end October 7, 2026, before entry; no current futures quote is supplied. Below, this study’s eight selected years supply a normalized average seasonal path over the next 60 weekdays, October 8–December 30. That separate horizon illustrates historical shape, not a price target.[5]

EIA’s November 10 outlook can revisit the storage cushion. Its conditional spot forecasts do not establish attainable futures returns.[1]

The amber line overlays a section of TradeWave's seasonal trend, scaled to the last recorded price, using 8 selected midterm-election years (1994–2022). Its displayed dates are 2026-10-08 to 2026-12-30; covering the next 60 weekdays. That is a different horizon from the full seasonal window above.

About this seasonal analysis

8 selected midterm-election years (1994–2022). The selected dates, years, direction, returns and ranges come from TradeWave. When a window boundary is a weekend or market holiday, TradeWave uses the next available trading session. SMN displays the returned results without recalculating them. A year label identifies the start of the historical window; a window can end in the following calendar year.

Green and red bars show the underlying adjusted-price movement. The range endpoints measure changes from the entry price, not a peak-to-trough loss. Historical results are before trading costs and do not guarantee future performance.
