description

Fetch and interpret Norwegian weather data from MET Norway's open APIs. Use when Codex needs forecasts, immediate precipitation nowcasts, subseasonal outlooks, tidal water forecasts, weather warnings, or sunrise and moon data for places in Norway, and the task should be solved with api.met.no products such as Locationforecast 2.0, Nowcast 2.0, Subseasonal 1.0, Tidalwater 1.1, MetAlerts 2.0, or Sunrise 3.0.

MET.no Norway Weather

Overview

Use this skill to choose the correct met.no product, build compliant requests, and interpret the results for Norway-focused weather tasks.

Prefer coordinates when they are already known. If the user gives a Norwegian street address, use the bundled helper's Kartverket geocoder via --address; it resolves official Matrikkelen addresses through the free Geonorge Adresse API before calling MET. For non-address place names, resolve to lat and lon first using local context or another approved geocoder, then call the MET API.

Choose The Product

• Use locationforecast/2.0 for general weather forecasts up to 9 days. Start with /compact unless the task needs percentile values or extra detail from /complete.
• Use nowcast/2.0 for the next 2 hours, especially if the user cares about immediate rain or snow in Norway. This product is radar-aware and updated every 5 minutes.
• Use subseasonal/1.0 for daily weather outlooks out to 21 days in the Nordic area. Prefer this when the user asks for a longer-range trend instead of a short forecast.
• Use tidalwater/1.1 for harbor-specific water level forecasts in Norway. Use this for storm-surge adjusted water levels, not for general ocean tide explanations.
• Use metalerts/2.0 for active warnings, warning history, or alert filtering by county, event, or coordinates.
