On the web, the arrows "bottom to top" (at least) are generaly totally wrong !

You are talking about the Route planner ! It is not the topic of this thread.
Apparently you have not understood what “bottom to top” or “left to right” means in the Route planner setting.

Imagine your boat is sailing from left to right on your screen. The TRUE WIND shown on the route planner diagram is as it appears at sea relative to the boat's heading.
So, it's not the relative wind resulting from the true wind and the boat's speeds i.e. the vector sum of the wind speed and the boat speed. It is the true wind (and waves) direction as it appears relative to the course of the boat from left to right of screen.
See more details here and here.
It is an alternative to North up because it shows when your route is heading into the wind or too close to the wind direction, being useful to forecast the point of sail (close reach, beam reach, broad reach…) along the route.
See how to use the Route planner

It is easy to reproduce the problem, just look at the map, imagine the wind on your sailing boat when you have your direction.

And the name "bottom to top", is not very good.
I would have preferred "relative to the boat".
Perhaps it will help the developper to find the solution ...

Thank you for the patience.

The latest update to the Android app does not fix the problem. The arrows clustered around the forecast location bear no relationship to the wind direction arrows in the table. Also, the colors of the wind direction arrows clustered around the forecast location, and the wind speeds on those arrows are completely unrelated to anything in the table.

We are frankly tired of waiting for a fix to this problem. I'm looking at your competitors such as windy.app.

Not a happy customer.

I also just checked the version 46.1, the tabulated data and the wind barbs seem to be consistent now. Also the data in the table does not change anymore when I change the model.

That looks ok.

This forum is quite confusing at times.

The fix that they released a few hours ago appears to have fixed the bug with the uncorrelated wind arrows and the wind direction table!

I guess, you meant to address your message to the Windy team?

@Suty what are the plans for releasing the updated version this week? At the moment I still get version 46.0.4 in the browser.

Using the correct button you can’t browse through your picture library ?

I don't know how much clearer to be. For example, let's say that all of the arrows in the column in the table indicate wind from due south. The arrows that cluster around the forecast point will be any random direction! They also don't have the correct wind speed.

I'm not going to attach a screenshot because your interface on mobile apps does not allow browsing through my local images. And I'm sick of having to take the time to upload an image to Google drive, copy the link, and then paste it in as a link. Your forum is one of the few that don't allow direct posting of images.

I've pretty much given up on you ever fixing this. I was trying to investigate your competition, Windy.app

This is sad because I've been a loyal subscriber to your app for almost 6 years now. I'm not sure what's happened, but clearly you're coding team needs a swift kick in the seat of the pants.

Disgusted,

Steve

Eagerly waiting for the update next week...!

Does the update only focus on the consistency of wind bards and tabulated data?

Or does the update also fix the current issue, that the tabulated data changes for all models, when I select a different model? For a reference, see my post from July 7th 21:05 above.
Please include this as well, from my perspective this is even more critical than the inconsistency of tabulated data and wind barbs.

With trying to run a National Championship Sailing event, Windy could be highly useful, however with present very light & variable conditions beneath a High-pressure ridge, this wind-barbs facility has become a ‘laugh’, unfortunately.

Now I'm not even bothering with Windy. It's useless and unusable currently.

You ought to be able to update your back end servers quickly, then take your time with version 47 of the app.

We are frustrated and tired of waiting. We wish that you would focus more on core functionality, instead of cool pretty new features. I personally was totally happy with the features that you had 3 years ago, and 3 years ago, the forecast for at least more accurate!

Can you please let me know, which of the wind-data that Windy shows in the tabular part at the lower part of the screen is valid and which is wrong?

I assume, you could discuss this with colleagues and at least give me some feedback, which wind-data correctly reflects the actual forecast of a certain model which wind-data is corrupt.

Even if fixing the bugs takes Windy some time, this would allow me to use it with more confidence.

Thank you in advance.

You write "probably 46.1 or 46.2 in upcoming weeks".
Please fast-track this!

These bugs are no "nice-to-have" thing. Fixing these bugs needs to to be re-prioritized as soon as possible in the dev-team at Windy.

Please realize, that currently you deliver plain wrong and misleading wind-data to your users. At least I know now and can act accordingly (= avoiding Windy). But others users, who do not follow this forum, might not have realized this. This is critical.

At least make sure, that the wind-data in the table at the lower part of the screen is consistent and correct. As I documented, currently the wind-data changes drastically for all models, depending on which model I chose.

The really sad thing about all of this is, that Windy worked perfectly fine before.
