Tide Forecast on Windy
-
Lots of good ideas mentioned to make valuable tool really great. Amust though is to show the moon phase. This is fritical in determining spring and neap tides - also has huge effect on local currents.
-
The feet to meters conversion doesn’t seem very accurate. For example, a tide shown as “14 feet” is also shown as “4.43m”. 4.43m is 14.53 feet, so which is it?
Half a foot can make a difference in a high tide, it could be the difference in flooding or not.

@ivo Tides layer is a nice addon but it's presentation feels outdated with the brown and blue lines compared to the rest of the app or website. To match the rest of the website which is very visual I was thinking about a tide chart with a sinusoidal curve with high and low points and a vertical line showing current time on the chart.

Tides are one of my important features, since I spend a significant time there. I would like to see the exact measurements I.e. decimals included. Thanks!

Fantastic and very useful addition to W. My daily go to for passage planning. Simple and complete. Thank you.

@SVFLIGHT @William-Cane @roadrunner40 @BlueMovement @Clark-Pine thank you for your interest in Tides. We considered it just a supplementary feature over the time. I am happy to read that you are using it. It seems that we should give it some facelift :)

@ivo Would you consider presenting tidal flows as a sine wave for all sites. The resultant visual presentation would make tidal estimates very quick as most mariners and boaties know the rule of twelfths

I just for fun compared the tide prediction by windy with those available at the german BSH.
It's not too bad, the times for high and low water are pretty close useful as guide on how to plan a passage. I was mainly puzzled by the hights shown in windy. There are negative values. So the values given are definitely not suitable for use in navigational calculations, which is totally ok because the feature is experimental.
What hight reference datum does windy use?
In marine navigation the usual reference datum for water levels/depth is LAT=lowest astronomical tide which is used as zero depth in nautical charts and which ensures that hights of tides are always positive (by definition) and depths in a nav chart are minimal depth. (Actual water level may get negative due to wind or other influences but not due to calculated tides.)

@Tomber42
Also needs to state day and date ie , wed 05 or Thurs 06 -
@Jungbl you forgot to mention that air pressure affects tides.
