The best time to visit Tamarindo weather-wise would be mid-November through August. The weather is pretty perfect during this time, most of the year. Even the rainiest months of September and October will see plenty of sunshine, although quite a few businesses close their doors at this time so that the town might feel a little dead. If you’re only in Tamarindo for the surf, it doesn’t matter how dead the town feels. It’s more about how alive the ocean feels, and the best waves around Tamarindo come between June and October. Likewise, wildlife lovers might find Tamarindo worthwhile between September and March, when the leatherback turtles come to nest on Playa Grande.

And then there’s the fishing. Yes, Tamarindo is also a fishing hot spot in Costa Rica with excellent, year-round, inshore fishing and offshore fishing that’s great from June to October. In addition, Tamarindo waters produce the largest and most numerous yellow-fin tuna from May to November.
