Tide Forecast on Windy
Good morning from Hamburg / Germany
The link from the BSH for the tide prediction in Germany has changed.
Here is the currently working link.
I refer to the website of BSH because it is the most accurate info. I would prefer having the same accuracy in an app. Preferably an app that also is available for my samsung smartwatch.
I am an avid sea kayaker and make use of tides and currents constantly, pulling from a variety of sources. I already use Windy for weather and swell predictions so it's great that you're now including this information. I have two suggestions for changes that would make what you've got much more useful:
For current stations only, add ebb and flood headings, that is, the compass direction of the ebb and flood directions. Without this information, the flood and ebb timing is often useless unless the station is in a very simple location (like a river mouth). As one example, where the East River joins the Harlem River in NYC, the definition of ebb/flood direction actually reverses as you go through the river confluence. If you don't know that, you can wind up making exactly the wrong decision! The definitions of ebb and flood are a bit arbitrary for waterways that connect two larger tidal bodies of water, and also for channels between islands where it is hard to guess which current is labeled which. This is why they are included in all NOAA current stations.
If it were possible to plug an arbitrary time/date into the tide/current stations (rather than just a time from the slider at the bottom) this would turn Windy into a full-blown tidal prediction app, which would make it a "one-stop shop" for those planning a trip in the future. But obviously this is more disruptive to the UI design.
Thanks for your consideration!
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.

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.
