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.
