+Noche de San Juan on June 23.

–Hurricane season begins.

June starts hurricane season, but the island celebrates Noche de San Juan on June 23 with crowds on the beaches.

Scores and crowd levels are my own judgement; temperatures are monthly averages. Higher scores are better: quieter, cheaper and more pleasant.
