The usefulness of historical data isn’t found in precise forecasts but in the stories and questions it helps raise. Each season leaves a mark, and the work lies in seeing patterns without jumping to quick conclusions.

Sifting through records to find weather patterns
After the first frost, I found myself looking back through years of rainfall logs and market receipts. The story they told was not of precision, but of slow patterns: dry years and their echoes in the bins, wet seasons marked by both hope and caution.
