How it works

Weather Genie looks at the weather on your chosen date in past years and averages it. It is a climate-based estimate, not a live forecast.

  1. Find the place. Your zip code, airport code or city becomes map coordinates.
  2. Gather the history. It pulls daily records for that date, plus or minus a few days, from the last 5 to 30 years.
  3. Average it. Highs, lows, rain chance, wind and the most common conditions combine into one prediction.

Data: Open-Meteo historical archive (ERA5 reanalysis), plus Zippopotam.us for zip codes. Values describe a grid area, not a single weather station. Good to know: it is best for planning ahead and cannot foresee a specific storm.
