@emarrero said in Add tides to "Distance and Planning":

....to see the tides and/or currents along the trip too.

Tides are only useful at starting and arrival harbours, or very close to the coast.
Adding currents would need to include tidal currents. But this data is not available on Windy.

A 'Tide Forecast' Layer is already available for certain locations.

At the bottom right hand corner configure the 'Quick Menu' by clicking 'More layers' and then turn ON the Tide Forecast.

If no Tide Reference Stations are displayed Windy may not have Tide data for your location (yet).
