Soon is time to become father, and together with the mother (who is danish and like to plan in advance

)we are thinking about having a nice travel somewhere when the kid will be old enough to do it, and she still on parental leave. The idea is to go in February when the little kid will be 6 months old and the winter at its worst in Denmark.
The place should be first of all baby friendly (no malaria or other disease areas) , a good kitespot for intermediate level, with a lot of wind in february, warm and possibly not too much turistic. The idea is to rent an apartment for one month there. I would like to avoid to have a car.
I researched a bit and so far the best alternative i found was Boracay in the Philippines, but everywhere I look i see wonderful places, so can anyone suggest anywhere after it's own experience?
Thank you very much in advance!
