MET Norway Weather Forecast Scraper 🌦️

Scrape free hourly weather forecasts for anywhere on Earth from the MET Norway (Yr / Norwegian Meteorological Institute) public API — no API key, no account, no rate-limit dashboard. Feed in latitude/longitude pairs and get up to ~10 days of hourly rows with temperature, wind speed and direction, precipitation, air pressure, humidity, cloud cover and weather symbols, exportable as JSON, CSV, Excel or via API.

Why this actor

• No API key. MET Norway's locationforecast/2.0 is fully open. Zero signup friction.
• Global coverage. Any coordinate on the planet, land or sea.
• ~90 hourly rows per location, one dataset item per forecast step — instantly chartable.
• Clean flat schema. No nested JSON to unpack; every field is a plain column.
• Cheap. Roughly $0.5 per 1,000 rows in Apify platform usage.
• Compliant User-Agent. The actor sends the descriptive, contact-carrying User-Agent MET Norway requires (see below).

What you get

Field	Description
location_name	Your label, or "lat,lon" when you didn't supply one
latitude, longitude, altitude	Resolved coordinates and station altitude in metres
time	Forecast timestamp, ISO-8601 UTC
air_temperature	Temperature in °C
air_pressure_hpa	Air pressure at sea level in hPa
relative_humidity	Relative humidity in %
wind_speed_ms	Wind speed in m/s
wind_direction_deg	Wind origin direction in degrees
cloud_cover_pct	Cloud area fraction in %
symbol_1h / symbol_6h	Weather symbol codes (e.g. cloudy, fair_day, rain)
precipitation_1h_mm / precipitation_6h_mm	Precipitation in mm
updated_at	When MET Norway last refreshed the model run
source, scraped_at	Provenance metadata

Input

{
  "mode": "forecast",
  "locations": ["52.52,13.405,Berlin", "59.91,10.75,Oslo"],
  "maxItems": 200
}

• mode — currently forecast (hourly rows per location).
• locations — "lat,lon" or "lat,lon,Label". The label lands in location_name.
• maxItems — cap on total rows (default 200, max 2000). One location ≈ 90 rows.

Use cases

• Weather apps & dashboards — a free, key-less backend for hourly forecast widgets and charts.
• Logistics & fleet routing — wind, ice and rain risk along delivery corridors before dispatch.
• Agriculture & irrigation — hourly precipitation and humidity for spraying, harvesting and watering windows.
• Event planning — rain probability and wind for outdoor venues, festivals and construction schedules.
• Energy & renewables — wind speed profiles for turbine yield estimates, cloud cover for solar output.
• Research & backtesting — build a longitudinal forecast archive by scheduling daily runs.

The required User-Agent (important)

MET Norway's terms of service require every client to send a descriptive User-Agent header containing contact information. Requests with a generic or missing UA are answered with HTTP 403. This actor sends a compliant identifying UA on both its transports (curl_cffi with a Chrome TLS fingerprint, and a stdlib urllib fallback), so you never have to think about it. Please keep runs reasonable — MET Norway funds this service publicly.

Tips

• Schedule a daily run to build your own forecast-accuracy archive.
• Raise maxItems when scraping more than two locations — the cap is shared across all of them.
• Use the overview dataset view for a quick location / time / temperature / symbol table.
• Symbol codes map 1:1 to Yr's public weather icon set, so you can render them directly.
