# Marine Forecast

Marine and sailing weather using Open-Meteo Marine API + Weather API. Free, no API key required, works worldwide.

Two APIs are used together — replace `LAT`, `LON`, and `TZ` in all commands:
- **Marine API** (`marine-api.open-meteo.com`) — waves, swell, sea temp, currents, tides
- **Weather API** (`api.open-meteo.com`) — wind, gusts, air temp, pressure, visibility

Find coordinates for any location using web search or the user's input. Use the nearest timezone (IANA format, e.g. `Europe/London`, `America/New_York`, `Atlantic/Canary`).

## Current conditions

Sea state:
```bash
curl -s "https://marine-api.open-meteo.com/v1/marine?latitude=LAT&longitude=LON&current=wave_height,wave_direction,wave_period,swell_wave_height,swell_wave_direction,swell_wave_period,sea_surface_temperature&timezone=TZ"
```

Wind and atmosphere:
```bash
curl -s "https://api.open-meteo.com/v1/forecast?latitude=LAT&longitude=LON&current=temperature_2m,wind_speed_10m,wind_direction_10m,wind_gusts_10m,apparent_temperature,pressure_msl,cloud_cover,visibility&timezone=TZ"
```

Run both and combine the results into a single briefing.

## Hourly forecast

Marine (up to 16 days, adjust `forecast_days`):
```bash

```

Wind (up to 16 days):
```bash
curl -s "https://api.open-meteo.com/v1/forecast?latitude=LAT&longitude=LON&hourly=wind_speed_10m,wind_direction_10m,wind_gusts_10m,temperature_2m,pressure_msl,visibility,cloud_cover,precipitation_probability&forecast_days=3&timezone=TZ"
```
