Compact format: curl -s "wttr.in/London?format=%l:+%c+%t+%h+%w"

Full forecast: curl -s "wttr.in/London?T"

Format codes:

• %c condition
• %t temperature
• %h humidity
• %w wind
• %l location
• %m moon

Tips:

• URL-encode spaces: wttr.in/New+York
• Airport codes work: wttr.in/JFK
• Units: ?m metric, ?u USCS
• Today only: ?1, current only: ?0
• PNG output: curl -s "wttr.in/Berlin.png" -o weather.png

Open-Meteo (fallback JSON)

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

Use this when you need structured fields like temperature, windspeed, and weathercode. Docs: https://open-meteo.com/en/docs
