hello! ! It seems that the tidal forecast data has been restored. Thank you for starting the topic!!

@tandemtime There are 2 currents layers in Windy. Currents which includes all type of currents. As wind is the main factor of ocean circulation, its effect is taken into account (but not sure for a local wind) https://marine.copernicus.eu/news/new-catalogue-release-wind-wave-ocean-current-and-biogeochemical-variables Tidal currents is deducted from variation of sea altimetry https://community.windy.com/topic/15265/tidal-currents?_=1614707415967 Concerning waves models, WW3 model is said to include the effect of surface currents, WAM model apparently not. Depending where you usually sail, these layers are interesting but it is advised to rely on other traditional and official information sources for currents and their effect on sea surface, specially near the coast.

@suthagar1 My link here above is no longer active. Anyway, you better ask to CMEMS from Copernicus. They provide data from My Ocean / Mercator Ocean based on sea surface altimetry prediction for tidal currents. And see: https://marine.copernicus.eu/access-data/myocean-viewer

@afurley All waves models don’t take into account the effect of current. For WAM model from ECMWF(July 2018): « Considerations when using output from ECWAM Not yet modelled are the interaction of waves with sea-surface currents. In particular areas, (e.g. Gulf Stream or Agulhas current), the current effect may give rise to localised changes of up to a metre in the wave height » From https://confluence.ecmwf.int/plugins/servlet/mobile?contentId=131397261#content/view/131397261 For WWW3 model it seems to be different (March 2019): https://github.com/NOAA-EMC/WW3/wiki/Manual Page 1 « The model [....] computes other transformation processes such as the effects of surface currents to wind and wave fields, and sub-grid blocking due to unresolved islands » Page 163 « 3.9 Winds and currents Model input mainly consists of wind and current fields. Within the model, winds and currents are updated at every time step ∆tg and represent values at the end of the time step considered. » In any case it would be much better for you to sail downwind and down swell. But this is quite tricky in the Agulhas current area, the swell being mostly from SW. Don’t you plan a stop in Durban?

@idefix37 Thank you! [image: 1530858165500-70a66faf-e505-426c-b84e-5ee6ce3190ce-%CE%B5%CE%B9%CE%BA%CF%8C%CE%BD%CE%B1.png] @administrators must fix it

@tubbssurf ECMWF-WAM and WW3. We use both and you can choose
