jjd,was 10 yrs since I went to costa rica.From memory it may be a bit wet at the time you're going.The west coast is the place for surf,east coast is nov/dec,great fun waves up & down the whole coast so pack your short board.playa negra in the north,in the mid coast near Jaco,take a boat to Escondida,filthy little reef(lefts & rights).South coast has a really long left but the name eludes me(its a river mouth).Best way to get around is to hire a 4x4.The locals are unbelievably friendly.It does get onshore there but kitesurfing was'nt around back then so I did'nt take much notice of the wind,but you will score some great waves in warm water.Hope this helps.

cheers Andrew
