The charms of Puerto Rico's capital are clear even from the air. Sky blue waters front notable structures, which in the end offer approach to tropical foliage. Flights to San Juan wind up at Luis Munoz Marin International (SJU), named for the author and statesman who is viewed as the "Father of Modern Puerto Rico." Since the island is a United States domain, it offers American accommodation wrapped in sunny 80-degree climate and provincial Spanish culture.

Best Times to Visit San Juan. The best time to visit San Juan is from mid-April to June, right after the busy winter season and just before the rainy summer. Spring weather is also very pleasant, barely escaping the mid-80s on most days.
