May typically marks the transition from the dry season to the wet season in Puerto Rico. Visitors can expect daytime temperatures averaging in the low 80s Fahrenheit (high 20s Celsius) with higher humidity than in the earlier months of the year. Rainfall becomes more frequent, often occurring in short, afternoon showers. Ocean temperatures remain warm, ideal for swimming and water activities.
Understanding the typical climate conditions for this period allows travelers to pack appropriately and plan activities accordingly. Historically, May offers a pleasant balance between the drier, cooler conditions of winter and the heavier rainfall of the summer months. This makes it an attractive time for those seeking a mix of sunshine and tropical showers, often with fewer crowds than peak season. Preparing for the potential of rain, however, is essential for maximizing enjoyment during a May visit.
