www.windfinder.com/windstatistics/diani_beachNot sure if it shows up on yours cause they gave me some special version forever ago cause i helped them make it but yeah
Id ignore everyone in person and ignore everyone online twice as much when it comes to "what they reckon the wind is like somewhere"
And ignore the kiters 3 times cause theyre all fat old men
If you cant quite understand the data try cross refrenceing it with your local spot where you "know" the wind to give you a proper gauge.
Theres a airport right at diani beach so the data is accurate
