The best time to visit Matapalo is during the dry season, which runs from December to April.
During these months, you'll experience consistently sunny days and lower humidity, making it ideal for enjoying the beaches and outdoor activities without interruption from rain. The ocean is typically calmer and clearer, superb for swimming, snorkelling, and diving.
For those looking to spot wildlife, especially for birdwatching or observing monkeys and sloths, the dry season offers easier viewing conditions as animals are less likely to be sheltering from rain. This period is also excellent for exploring Corcovado National Park, as trails are dry and more accessible.
While May to November is the rainy season, you can still have a good trip, particularly in May, June, and early July, when rain usually comes in short, heavy bursts in the afternoons, leaving mornings sunny. This "green season" brings lush landscapes and fewer crowds, and you might find better value on accommodation.
