The best time to travel, beyond weather patterns, will depend on what kind of activities you’re interested in doing. If you are looking to explore nature, wildlife spotting, visit waterfalls, do a canopy zip line tour, or just chill at the beach and maybe learn how to surf, you are in luck as they are year-round activities in Manuel Antonio. Fishing is excellent all year, but what you’ll likely hook also depends on the month. Yellowfin tuna and dorado are caught all year. However, Blue Marlin is biting like crazy from April through September. You can also enjoy whitewater rafting on class II-III-IV rapids in this area. Rapids are more complex, faster, and more challenging during the summer and fall (June-October). March and early April are the ends of the dry season, and the water level drops, so if a rafting adventure is on your bucket list, best to avoid these months. If you hunt for whales, the best time to do whale watching in Costa Rica is from August through October, when humpback whales come to breed and raise their young. The most spectacular central Pacific whale watching is located south of Dominical in Ballena Marine National Park.
