Different data Web version versus iOS version.
I can see differencies in wind data between web and iOS. Example spot Alimos Marina at Saturday 29/6 at 15 pm is 10 kn on your website and 19 kn on iOS application. Could you explain it ? Thank . Jan
There are different forecast data, at different models.
... also you can use the wind comparison (gusts included)
As @Gkikas-LGPZ said, you selected probably 2 different models on your devices.
Here are screenshots with website and with iPhone. There is just 1kt difference for Gusts.
