# 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.
