@Andrew-Ongley Hi, Are you referring to the Tide POIs which are based on local tide gauges ? [image: 1783761557719-26733722-3c82-4de8-89aa-05ca44dd52ce.jpeg] Or to the tide graph in the wave panel ? [image: 1783761610502-86217193-3cdc-43c2-ba33-f019f54e18c4.jpeg] The tide data of this graph is computed by WorldTides. But, due to their low resolution, they are likely inaccurate in enclosed bays. I have already verified this in similar situations.
