April is the most popular month to visit Rio San Juan, as it marks the beginning of the peak travel season that extends through June. During this time, travelers flock to the area to soak up the sun, enjoy the breathtaking beaches, and engage in exciting outdoor activities like snorkeling and diving in the crystal-clear waters. The vibrant atmosphere, combined with the warm temperatures, usually ranging from the mid-70s to mid-80s Fahrenheit, creates an inviting environment superb for exploring the natural beauty of the region.
For those who prefer a quieter experience, visiting in December offers a charming alternative. This month brings a delightful ambiance with fewer tourists, allowing for a more relaxed exploration of local attractions, such as the stunning Playa Grande or the picturesque El Salto waterfall. The weather remains pleasant, making it an ideal time for leisurely beach strolls and enjoying the lush landscapes.
Ultimately, the best time to book a vacation rental in Rio San Juan depends on your preferences. If you thrive in lively settings with plenty of activities and social opportunities, April to June is your best bet. However, if you seek tranquility and a chance to appreciate the area's beauty without the hustle and bustle, December could be the superb choice.
