#temperature

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.
