# 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 (3 days):
```bash
curl -s "wttr.in/London?T"
```

### Querying by time range

Current weather only:
```bash
curl -s "wttr.in/London?0&format=3"
```

Today's forecast:
```bash
curl -s "wttr.in/London?1&T"
```

Tomorrow's forecast:
```bash
curl -s "wttr.in/London?2&T"
# Shows today + tomorrow; extract the second day
```

Day after tomorrow:
```bash
curl -s "wttr.in/London?T"
# Default output shows 3 days (today, tomorrow, day after tomorrow)
```

Next 7 days (weekly forecast) — use Open-Meteo:
```bash
curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12&daily=temperature_2m_max,temperature_2m_min,weathercode&timezone=auto&forecast_days=7"
```

### 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)
- Language: `?lang=ja` (Japanese), `?lang=zh` (Chinese), etc.
- PNG: `curl -s "wttr.in/Berlin.png" -o /tmp/weather.png`

## Open-Meteo (fallback / extended forecasts, JSON)

Free, no key, good for programmatic use and longer-range forecasts.

Current weather:
```bash
curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12&current_weather=true"
```

7-day daily forecast (min/max temp, weather code):
```bash
curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12&daily=temperature_2m_max,temperature_2m_min,weathercode,precipitation_sum&timezone=auto&forecast_days=7"
```

Hourly forecast for the next 2 days:
```bash
curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12&hourly=temperature_2m,weathercode,precipitation&timezone=auto&forecast_days=2"
```

Find coordinates for a city, then query. Returns JSON with temp, windspeed, weathercode.
