🌤️ Open-Meteo — Weather Forecast & Historical Data — Apify Actor

Scrapes weather forecasts, historical weather, and air quality data from the Open-Meteo API. Supports multi-location batch queries, 50+ weather variables, city name geocoding, and data going back to 1940. No API key required.

Features

• 3 data modes — forecast (up to 16 days), historical (1940–present), and air quality.
• Multi-location — batch query any number of cities or coordinates in one run.
• Auto-geocoding — type city names like Lahore, PK — coordinates are resolved automatically.
• 50+ weather variables — temperature, precipitation, wind, humidity, UV, cloud cover, soil, solar radiation, and more.
• 21 air quality variables — PM2.5, PM10, ozone, NO₂, CO, pollen, AQI indices.
• Hourly + Daily — fetch either or both granularities.
• Unit selection — °C/°F, km/h/mph/m·s⁻¹/knots, mm/inches.
• WMO weather codes decoded into human-readable descriptions.
• 4 output formats — one-per-day, one-per-hour, one-per-location, raw.
