I hope you are not expecting much wind.
Fuerte is only consistently windy in the Summer months.
Winter I would say its 20% Chance of wind. You may get lucky and get a storm and get 4 days of wind in a row, but it's luck of the draw..
Bring at least a 3mm wetsuit the water does get cold in the Winter nowadays.
The good news is that the Surf will be good, so if you can Surf too then you will have a great time, but again you are gonna have to drive somewhere to do that. You have chosen to stay in the most touristy town on the Island. The beach there is completely protected from wind as waves.
Either way you will have to drive 30minutes to the North or an Hours to the south to go kiting, There are no launches anywhere near Caleta.
At least you are staying right next to the only McDonalds on the Island.
If you are there you can always give Flag Beach a call and find out what the Wind is doing.
The Beach number is:
+34 609 029804
