When retailers talk to Wall Street, weather usually gets mentioned as a footnote—an “external factor” that explains away a tough quarter.

But in Home Depot’s Q2 2025 earnings call, weather wasn’t a footnote. It was a driver.

The company’s results show how extreme heat and July rainfall gave the home improvement giant a powerful tailwind, reversing a sluggish spring and delivering the strongest comps in two years.

The lesson? Weather isn’t background noise—it’s a business KPI.
