Tools (10)

`get_astronomy`read-only	Get sun and moon data: sunrise, sunset, dawn, dusk, day length, moon phase, illumination, moonrise, moonset.
`get_conditions`read-only	Get unified weather + marine + astronomy data in one call. More efficient than calling each separately.
`get_history`read-only	Get historical tide predictions and weather data for past dates. Tides up to 365 days, weather up to 90 days.
`get_marine`read-only	Get ocean and wave forecast (wave height, swell, sea state on Douglas scale). Returns hourly and daily data.
`get_observations`read-only	Get real-time sea level observations from REFMAR/SHOM tide gauges (French stations only). Returns 10-minute interval readings.
`get_radar`read-only	Get rain radar tile URLs for a location. Returns past frames and short-term nowcast frames for map overlays.
`get_tides`read-only	Get tide predictions (high/low water times and heights) for a port or coordinates. Returns extremes with datetime, height in meters, and type (high/low). Supports 13,000+ stations in 180 countries.
`get_weather`read-only	Get weather forecast (temperature, wind, precipitation, UV, conditions) for a port or coordinates. Returns hourly and daily data.
`list_countries`read-only	List all 188 countries that have tide stations, with their station counts and ISO codes.
`search_ports`read-only	Search for tide stations by name or country. Returns port name, slug, coordinates, timezone, country.
