Hot days cost yield. Now they can pay you back.
Heat stress at flowering can take 4% of your yield per degree over 29.5°C.
Watch this short briefing from Jonathan Barratt (CEO, CelsiusPro Australia) on how parametric weather certificates automatically trigger cash payouts to Australian broadacre growers in under 20 days when temperatures spike at flowering.

Why Heat Stress at Flowering is Fatal to Canola Margins
Australian canola represents $2.85+ billion in national income across 2.5–3 million metric tonnes. But unlike cereals, canola is acutely vulnerable to heat during flowering and early podding.
Malcolm Morrison Threshold
AAFC research scientist Malcolm Morrison demonstrated that canola experiences rapid pollen sterility and flower abortion as soon as daily temperatures cross 29.5°C during flowering.
The 4% Per Heat Unit Rule
For every Heat Stress Unit accumulated (°C over threshold x days), field trials confirm an average 4% yield loss. Two days at 32°C trigger a 20% crop loss.
45-Day Critical Window
Australian research (Angadi et al., Gan et al.) proves the critical period spans 2 weeks after first flower through 2 weeks post-flowering (typically Aug 1 – Sept 15 in Southern NSW).
Morrison & Stewart (2002) Research: Heat Stress Units vs. Canola Yield Loss
Documented field observations of accumulated heat stress during peak canola flowering
| Heat Stress Units | Example Temperature Condition | Calculated Yield Loss (4% per unit) | Crop Impact |
|---|---|---|---|
| 0.5 Units | 1 day at 30.0°C | -2.0% | Initial Mild Strain |
| 1.0 Units | 1 day at 30.5°C (or 2 days at 30.0°C) | -4.0% | Early Floral Abortion |
| 3.0 Units | 2 days at 31.0°C | -12.0% | Moderate Sterility |
| 7.5 Units | 3 days at 32.0°C | -30.0% | Severe Sterility |
| 13.5 Units | 3 days at 34.0°C | -54.0% | Catastrophic Failure |

Simulate Your Heat Stress Exposure & Parametric Recovery
Based on Morrison's 4% per Heat Stress Unit formula & CelsiusPro certificate terms.
Drag to set your strike threshold. Heat Stress Units accumulate for every °C the daily max sits above this strike during the heatwave.
Simulated Financial Outcome
| Metric | Unhedged | Hedged |
|---|---|---|
| Accumulated HSU | — | 10 units |
| Est. Yield (t/ha) | 1.08 | 1.08 |
| Yield Lost (tonnes) | -270 t | -270 t |
| Harvest Revenue | $810,000 | $810,000 |
| Revenue Lost to Heat | -$202,500 | -$202,500 |
| Certificate Payout | $0 | +$500,000 |
| Net Financial Position | $810,000 | $1,310,000 |
Formulas & Assumptions
• Accumulated HSU = max(0, Avg Max − Strike) × Days = (32°C − 27.0°C) × 2 = 10 units
• Certificate Payout = 10 × $50,000 = $500,000 → capped at $500,000
• Yield Loss = 4% × max(0, Avg Max − 29.5°C) × Days = 4% × 5 = 20% · Lost = 270 t of 1,350 t
• Est. Yield = 1.35 − (1.35 × 20%) = 1.08 t/ha
• Unhedged Loss = 270 t × $750/t = $202,500
Yield loss is modelled against the fixed 29.5°C science threshold (Morrison & Stewart 2002); the certificate payout accumulates against your chosen strike. Illustrative simulation only — not a quote or binding offer.
