April - October
April is the early start of the dry season, with temperate weather. It’s a good time to see larger birds like eagles, and temperatures are cool enough that daytime hikes are comfortable. The dry season typically lasts through October. This time of year brings bright days with eight hours of daylight, and comfortable temps with highs generally hovering around the low to mid 70’s F, making this time of year the best time to visit.
April through October is also when roads are more accessible for driving throughout the country. Plus, these months are prime for hiking, surfing, diving and spotting animals. Surfing conditions are best in April and May, while August, September and October are great for diving and snorkeling. And in the middle to the latter part of the season, you'll improve your chances of seeing baby lemurs, humpback whales, and various bird species. But also keep in mind, hotels and airfare will be more expensive from April to October (especially in July and August when school is out for the summer), so book several months in advance to ensure availability.
