The best time to go to Portillo, Samaná, is during the dry season, which runs from December to May.
During these months, you'll experience consistently sunny days and comfortable temperatures, typically ranging from 25°C to 30°C. This period avoids the heavier rainfall and higher humidity that can occur outside of these months, ensuring your beach days and outdoor activities aren't interrupted.
For those looking to witness the spectacular humpback whale migration, the peak viewing season is from mid-January to mid-March. This is an incredible experience, with thousands of whales returning to the warm waters of Samaná Bay to calve and mate. Many operators offer boat trips from nearby Samaná town, making it an easy day trip from Portillo.
Couples often find the shoulder months of December, January, April, and May particularly appealing. The weather is still excellent, but it's generally a bit less crowded than the peak whale-watching period, offering a more relaxed and intimate experience.
