It rains a lot in Tortuguero. The driest months are February/March, and September/October. Often, it rains during the night and the days are clear until 3pm or so.  Other times it may rain for 15 days straight.   If you stay with one of the full service lodges, they will provide ponchos and rubber boots for you, but bring along rain gear just in case. Just don’t let the rain prevent you from going out and exploring.
