Hi, I´m based in Costa Rica, and sail out of the port of Puntarenas. Feb and Mar are great months to sail, no rain and great wind, albeit sometimes agressive. The well known Papagallos can get upwards of 30 knots, especially in the north Pacific coast. Depending on what you want to do and the amount of time, I would suggest staying in and around the Golfo de Nicoya, and maybe as far north as El Coco. Another alternative is to go to the middle Pacific, around Quepos. The other option, again depending on your plans, is to stay in Golfo Dulce in the south. The Caribbean is not really an option for sailing in Costa Rica.
