Will any Category 4 hurricane make landfall in the US in before 2027?

Overestimating short-term impact (Amara's Law). AI estimates 29% vs market's 38%, suggesting the market overprices this outcome.

📊Free Summary

We believe the Category 4 hurricane US landfall market at 39% is overvalued. The historical base rate for a Cat 4+ US landfall in any given year is approximately 12-15%. While the 2025-2026 period features elevated SSTs (sea surface temperatures) that could amplify hurricane intensity, the specific requirement of Cat 4 at landfall (not just Cat 4 at peak) dramatically narrows the probability. Most major hurricanes weaken before landfall.

📐Key Metrics

1
12-15%Historical Base RateSince 1900, Cat 4+ hurricanes have made US landfall in approximately 12-15% of hurricane seasons.
2
WeakeningThe Landfall GapMost Cat 4+ hurricanes weaken before landfall due to wind shear, dry air, and interaction with the continental shelf.
3
+1.5°C SSTThe Warming FactorAtlantic SSTs are ~1.5°C above average, which can fuel stronger storms but doesn't guarantee Cat 4 US landfall.

Key Findings

  • 39% vs. 5%: Our AI Is Too Low — While 39% overestimates, our AI's 5% underestimates by ignoring elevated SSTs and the current hyperactive hurricane cycle.
  • Base Rate: 12-15% — In 125 years of records, Cat 4+ US landfalls occur roughly once every 7-8 years. The market's 39% implies once every 2.5 years.
  • Elevated SSTs Add Risk — Above-average sea surface temperatures fuel more intense storms, potentially raising the base rate to 18-22%.
  • Landfall ≠ Peak Intensity — Many powerful Atlantic hurricanes miss the US coastline entirely or weaken before impact. Harvey, Irma, Michael made Cat 4 landfall but most don't.
  • Two-Year Window — This resolves 'before 2027,' giving two hurricane seasons (2025 remnant + full 2026). Two seasons at 18-22% each ≈ 33-40%.
