#ocean

Marine and surf forecasts as an API, powered by Open-Meteo — clean JSON, no key. Get the current sea state and the hourly and daily wave forecast for any coastline by latitude/longitude or simply by place name: significant wave height, period and direction, plus the swell and wind-wave components broken out separately, and daily maxima and dominant directions. A built-in geocoding helper turns a place name into coordinates. Forecasts run up to ten days ahead. Live forecast data straight from Open-Meteo's marine model. Ideal for surf-report apps, sailing and boating tools, coastal and marine-operations dashboards and beach widgets. 4 data endpoints. Authenticated with an x-oanor-key; fair-use rate limits per plan.

Live marine weather and ocean conditions from NOAA's National Data Buoy Center (NDBC). The station catalogue (1,930 moored buoys and coastal stations worldwide) is searchable by name, type or coordinate; the live endpoint returns the latest observation for any station: significant wave height, wave period and direction, water and air temperature, wind speed/gust/direction, atmospheric pressure and more. Find the nearest buoys to any lat/lon. Ideal for surfing & sailing apps, marine operations, coastal monitoring and oceanography.

High and low tide predictions for thousands of US coastal stations, powered by NOAA CO-OPS. Search the station directory by state or name, pull full station metadata (coordinates and time zone), and get tide predictions as high/low events or an hourly height series for up to seven days, in feet or metres and against the datum of your choice (MLLW, MSL, MHHW and more). Delivered through a fast, reliable API with clear errors for invalid stations. Ideal for boating and sailing, fishing and surfing, ports and logistics, beach and tourism services and coastal planning.

Real-time and forecast ocean conditions for any coastal or open-water location. Get the current sea-surface temperature (in °C and °F) together with a wave snapshot — height, direction, period, swell and wind-wave — pull an hourly series of temperature and waves, or a daily forecast with sea-temperature min/avg/max and wave aggregates. Global ocean coverage sourced from Open-Meteo’s Marine model, delivered through a fast, reliable API; inland coordinates return a clear not-found so you always know you have ocean data. Ideal for surf and sailing apps, fishing and diving, beach and tourism services, shipping and coastal or climate monitoring.
