The short answer: the rainy season in Manuel Antonio, often called the green season, runs from about May to November. It rarely rains all day: mornings are usually bright, and showers tend to come in the afternoon or evening. September and October are the wettest months. It is a lush, quieter and often better-value time to visit, if you plan your outdoor time early.
