What This Skill Does

Fetches current weather conditions and forecasts via curl from wttr.in or Open-Meteo, with no API key required. Supports plain-text, compact, and PNG output formats.

Replaces signing up for weather API keys and writing custom HTTP requests by providing ready-to-use curl commands for instant weather data.

When to Use It

  • Check today's weather for a city before heading out
  • Get a quick text forecast for a location in a terminal or script
  • Retrieve current temperature, humidity, and wind speed in compact format
  • Download a weather PNG image for a city to embed in a dashboard
  • Query programmatic JSON weather data for a set of coordinates

Install

$ openclaw skills install @legionspace-hackathon/weather

Weather

Two free services, no API keys needed.

wttr.in (primary)

Quick one-liner:

curl -s "wttr.in/London?format=3"
# Output: London: ⛅️ +8°C

Compact format:

curl -s "wttr.in/London?format=%l:+%c+%t+%h+%w"
# Output: London: ⛅️ +8°C 71% ↙5km/h

Full forecast:

curl -s "wttr.in/London?T"

Format codes: %c condition · %t temp · %h humidity · %w wind · %l location · %m moon

Tips:

  • URL-encode spaces: wttr.in/New+York
  • Airport codes: wttr.in/JFK
  • Units: ?m (metric) ?u (USCS)
  • Today only: ?1 · Current only: ?0
  • PNG: curl -s "wttr.in/Berlin.png" -o /tmp/weather.png

Open-Meteo (fallback, JSON)

Free, no key, good for programmatic use:

curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12&current_weather=true"

Find coordinates for a city, then query. Returns JSON with temp, windspeed, weathercode.
