Weather

Two free services, no API keys needed.

wttr.in (primary)

Choose one request that matches the user's scope. Do not fetch current conditions separately when a today or forecast request already includes them.

Platform notes:

  • On Windows PowerShell, use curl.exe; bare curl may resolve to Invoke-WebRequest.
  • On macOS and Linux, use curl.

Current conditions only:

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

Custom current conditions format:

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

Today's weather, including current conditions (use this single request for questions about today's weather):

curl -s "https://wttr.in/London?1&m"

Full forecast:

curl -s "https://wttr.in/London?T&m"

On Windows PowerShell, replace curl with curl.exe in the commands above.

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 (macOS/Linux): curl -s "https://wttr.in/Berlin.png" -o weather.png
  • PNG (Windows PowerShell): curl.exe -s "https://wttr.in/Berlin.png" -o 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.
