Attention waves in North Atlantik wrong!!
-
The massive wave West of Irland and Schottland about 14m (Feb. 10 2020) are shown with 0 or 1 meter , we hope no sailer uses this map.

How did you get that?
On Waves layer I see 12.3 m for WAM model and 13.8m for WW3.
Nothing is wrong !
Or did you use the Swell layer?
(Wave layer with customised colours) -
Official sea wave height forecast from NOAA confirms max. 13 m.
-
Winds 45~50 kts

@idefix37 I used https://www.windy.com/-Swell-swell1?swell1,45.629,-13.799,5
And still see some areas with 0 waves. -

Hello, as @idefix37 and @Gkikas-LGPZ mentioned, there is a difference between swell and waves layer.
You can read the exact explanation of swell layer here - Description of layers -
@eduardheindl
Before posting « Attention waves in North Atlantic is wrong » you should try to understand the difference between Waves, Swells and Wind waves !
If you are sailing in North Atlantic you will observe waves. Their significant height and period correspond to what is called the sea state or the total sea. On Windy this is shown by Waves layer.
Why Swell was almost forecast near 0m? It’s because swell is a wave system generated by a REMOTE wind. In the case of this storm in North Atlantic the waves were only due to the strong LOCAL wind, NOT to a strong remote wind. You can check it by the Wind waves layer which shows the waves generated by the local wind you observe.
Even if it’s not absolutely exact, you may consider that
Waves (sea state) = Wind waves + Swell
So you may have
14m Waves = 13m Wind waves + 1m Swell
Sailors can use with confidence the Windy maps which are based on 2 of the most reliable global wave models. -
@idefix37 thanks for clearing my question!
