PredictCurrent's Tidal Current data is proprietary to PredictWind. PredictWind collaborates with a world-leading oceanographic company to develop the modelling, and PredictWind runs the model.

Resolution is provided at 100 metres, 400 metres, and 4 kilometres. Please see the world coverage map at predictwind.com/world-coverage and scroll down this page to view the high-resolution Tidal Current coverage map.

You can now see the current flow in incredible detail and accuracy, with a 400m resolution model within 90 km of the coast and a 4km resolution out to 600 km further offshore.

In areas with complex bathymetry and high tidal flows, an ultra-high resolution PredictCurrent tidal model is available down to 100m resolution for even greater accuracy. Below is an example of a location showing for which region each resolution is available.

There are no atmospheric influences or non-tidal effects, like freshwater rivers, flowing into the salt sea in this modelling. Global tidal models are depth-averaged. Parameters such as snow melt, rainfall, salinity and temperature are not considered or resolved in PredictCurrent's tidal model. In most cases, this is not an issue; however, it is a refinement for future consideration.
