Why Natural Gas Is So Seasonal
Demand Drivers
- Winter Heating (Nov-Feb): Residential and commercial heating
- Summer Cooling (Jun-Aug): Power generation for AC
- Industrial Use: Consistent year-round base demand
Supply Factors
- Storage Cycles: Injection season (Apr-Oct), withdrawal (Nov-Mar)
- Hurricane Season (Jun-Nov): Gulf production disruptions
- LNG Exports: Growing impact on US prices
The December Paradox
Despite December being peak heating season, natural gas often falls sharply:
- Buy the rumor, sell the news: Prices rise in anticipation, fall on reality
- Weather forecasts: Warm winter predictions tank prices
- Storage levels: Well-stocked inventories reduce urgency
Trading Strategies
Strategy 1: Spring Surge
Buy: Late March / Early April Sell: Late May Rationale: Captures injection season optimism (80% April win rate)
Strategy 2: Pre-Winter Rally
Buy: Early August Sell: Late September Rationale: Captures hurricane season fears and winter positioning (80% win rates)
Strategy 3: Avoid December
Strongly consider reducing natural gas exposure in December, historically down -13.73% with only 20% win rate.
