Historical and forecast daily weather metrics for global cities
Dataset Description
Daily historical weather observations and daily weather forecasts retrieved from the Open-Meteo API. The dataset includes temperature, precipitation, snowfall, radiation, weather codes, sunrise/sunset times, and other daily metrics for a set of population-ranked cities sourced from @geonames.geonames.
The dataset includes two long-format tables:
- historical_daily_weather – historical daily observations
- forecast_daily_weather – all forecast runs accumulated over time
Forecast data retains every forecast run, enabling backtesting, forecast comparison, and analysis of forecast accuracy over time.
