Introduction
# Weather
Two free services, no API keys needed.
## wttr.in (primary)
Quick one-liner: ```bash curl -s "wttr.in/London?format=3" # Output: London: ⛅️ +8°C ```
Compact format: ```bash curl -s "wttr.in/London?format=%l:+%c+%t+%h+%w" # Output: London: ⛅️ +8°C 71% ↙5km/h ```
Full forecast: ```bash 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: ```bash curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12¤t_weather=true" ```
Find coordinates for a city, then query. Returns JSON with temp, windspeed, weathercode.
