Captures price moves driven by weather forecast changes and extreme weather events
| Strategy Type | Fundamental / Event-Driven |
| Market Outlook | Captures price moves driven by weather forecast changes and extreme weather events |
| Risk Profile | Medium-High - Weather-driven moves can be explosive but forecasts can shift |
| Reward Profile | 3:1 to 5:1+ risk-reward on successful weather plays; potential for outsized gains |
| Time Horizon | Days to weeks depending on weather pattern duration |
| Iv Environment | Best during weather extremes (cold snaps, heat waves); quiet during mild periods |
| Breakeven | Entry price plus spread; weather catalyst must materialize for profit |
| Primary Instruments | Natural Gas CFD via IG/CMC/Pepperstone (NATGAS/XNGUSD); Henry Hub futures via IB |
| Asic Compliance | ASIC regulated; CFD leverage limits apply (10:1 max for commodities); retail client protections in place |
| Contract Size | CFD: Typically A$1 per 1 cent move (varies by broker); Futures: 10,000 MMBtu per contract |
| Trading Hours | CFDs: Near 24 hours Mon-Fri; Weather impacts often reflected in US session |
| Recommended Timeframe | Daily for weather pattern analysis; 4H for entry timing |
| Settlement | CFDs cash settled; positions can be held through weather events |
| Tax Treatment | CFD profits taxed as income (no CGT discount) |
| Weather Timing | US weather forecasts update during Australian night; review each morning AEST |
| Chess Sponsorship | Not applicable - Weather play uses CFDs/futures, not ETFs |

Natural gas prices you trade (Henry Hub benchmark) are based on US supply and demand. US weather drives US natural gas demand. When it's cold in the US, prices rise globally. Australian weather has minimal impact on Henry Hub prices.
Heating Degree Days (HDD) measure cold below 65°F - relevant for winter heating demand. Cooling Degree Days (CDD) measure heat above 65°F - relevant for summer cooling (air conditioning) demand. Both indicate energy demand for temperature control.
December through February (US winter) offers the best opportunities due to high heating demand sensitivity. Cold snaps can cause 20-50%+ rallies. Summer (June-August) offers moderate opportunities from heat waves. Shoulder seasons (spring/fall) have limited weather impact.
Prices often react within hours of significant forecast changes. Major model runs (GFS, European) update multiple times daily. When a forecast shifts (e.g., cold pattern emerges), prices typically begin moving on the same day. This is why monitoring forecasts is essential.
Compare GFS and European model forecasts at sites like tropicaltidbits.com. Agreement means both show similar temperature patterns (both cold or both warm). Disagreement means one shows cold while other shows warm. When models disagree, wait for convergence before trading.
No. Trade only when: 1) HDD deviation exceeds 10%, 2) Duration is 5+ days, 3) Models agree, 4) Event affects major population centers, 5) Price isn't already extended. Selectivity leads to better win rates. You might only take 4-8 major weather plays per winter.
Start with 50% position when forecast first confirmed at 7-10 days out. Add 25% when forecast holds at 4-7 days out. Add final 25% as event approaches if still on track. This approach limits risk if forecast changes early while building to full size on confirmation.
If the event is more extreme than forecast, prices may spike beyond initial expectations. Trail your stop tightly to capture the extended move but be prepared for sharp reversal when event ends. Don't add new positions at extreme prices - capture windfall on existing position.
Key model runs update during Australian night (European 12z at 6 AM AEST; GFS 00z at 2:30 PM AEST). Check forecasts each morning for overnight changes. If forecast has shifted significantly against your position, exit or reduce early - don't wait for further deterioration.
Collect daily temperature forecasts for major cities. Calculate HDDs for each city (65 - temp if positive). Weight by city population or regional gas consumption. Sum weighted HDDs. Compare to 30-year normal for that date to calculate deviation. Track deviation vs historical price responses to calibrate expected moves.
During El Niño: Expect generally warmer northern US winters; apply bearish seasonal bias; be more selective with cold play entries; consider fading weather rallies. During La Niña: Expect colder northern US winters; apply bullish seasonal bias; more aggressive on cold plays; less likely to short weather.
Use weather for directional bias (bullish forecast = look for longs). Use technicals for entry timing: Enter at support, when RSI oversold, or on pullback to EMA - even if weather is bullish. This prevents chasing extended moves. Use technical stops rather than arbitrary weather-based stops.
Demand-side (cold/heat): More common and predictable. Supply-side (production freeze): Rare but extreme impact. Winter Storm Uri (Feb 2021) froze Texas production, causing prices to spike from $3 to $24+. Supply events are less predictable but can combine with demand events for extraordinary moves.
Compare price level vs forecast strength. If prices have rallied 15% but forecast only shows moderate cold, weather may be priced in. Enter on forecast CHANGES (upgrades/downgrades) rather than existing forecasts. If prices haven't moved much despite strong forecast, opportunity remains. Technical analysis helps identify if move is extended.
