Tide Forecast on Windy



  • Lol, for how many years people have been asking for graphic representation of tidal data?

    I asked personally 2 years ago and sadly nothing changed.

    It doesn't seem like anyone cares here. Poor tidal data is one of the reasons I stopped using windy for kitesurfing. Sad considering how much other data is here... I mean, ozone layer? Who cares... Just give us what we need most.



  • After taking a closer look it seems that at least some of the tidal currents Windy is reporting for the US is quite a bit different from what the government NOAA website predicts. This makes me hesitant to use Windy until there's an explanation of what's going on.

    As an example, I looked today at tide station Upper Hell Gate, Sasanoa River (ACT0596). Windy has this data for February 11, 2020:
    10:16 AM Slack, Flood Begins 1h 7m ago, 0kt
    1:11 PM Max Flood in 1h 48m, 1.26kt
    5:01 PM Slack, Ebb Begins in 5h 38m, 0kt
    11.2 at 7:25 PM Max Ebb, -1.28kt

    But NOAA has this data:
    2020-02-11 11:47 AM slack -
    2020-02-11 01:19 PM flood 1.31
    2020-02-11 03:34 PM slack -
    2020-02-11 06:59 PM ebb -1.06

    As you can see, the times given for slack is 90 minutes too late in Windy. (I also checked a number of other sites which are very close or identical to NOAA, and my experience on the water is that NOAA gets these predictions quite accurately.)

    What's the reason for this discrepancy?



  • I love tides, but it's only useful for the tides today. It doesn't show the date so I can't use it for forecasting tides. Can you please show tide dates?

    @jberkovitz This all depends on the harmonical constants we have for given spot. Based on those, tides are calculated for the future (but also for the past!). NOAA has most likely some newer, more accurate constants for given spot, I will check if there is a new DB available.

    @GlenGitsham the dates are there, what exactly and where are you missing?

  • @WharfRat yes your spot on a tide graph as you have submitted is easy to read in a kayak or small boat being thrown about by waves, and entering bar ways and small river/waterways.
    i rely on tide info with weather conditions a lot in my fishing pursuits and need to have weather and tide info several days in advance as well. this app is now my go to app for all conditions related to my fishing.



  • @kekert i think like me he would like to be able to see the tidal info several days in advance to be able to work in with weather forecasts to make planing a fishing trip or other activities, a good app there well done, please keep tides going. thank's.



  • Hi there,

    Sorry reviving an old thread, I have no idea if this is the correct way to do it... I was thinking, maybe it could be added to the alerts section something like the Nautide app notifications? Eg.: Everytime a certain station has high-tide or lowering tide, etc, I get an alert about it.

    Would be nice to have an alert about when the tide is high, or when it's lowering (or when it's low tide, I think you got the idea), since I keep track of some local data for some personal projects.



  • @idefix37 I'd leave the choice to the settings which the user has set up in Windy settings as far as ft and m. Yes, a graphical screen would be a great addition too.

    Hi, Yes I fully agree with you, both for the units and the graph.



  • Love the tide information—- very important to us, as boaters. We Cruise are on the east Coast of the US. I noticed that some of the tide station data reflects current (slack tide, for example, at St Johns River in Florida). Some of the tide stations do not (St Mary’s inlet in Georgia). I would love to see this information at all the inlets (I know the data exists).

    Thank you
