June weather forecast
Puerto Rico, USA

June in Puerto Rico brings the onset of summer, with the island firmly entrenched in its wet season. Temperatures continue their upward trajectory, starting from lows around 76°F (24.4°C) and soaring to highs of about 89°F (31.7°C). This ascent from May is modest, yet the warmth becomes more palpable, especially when coupled with the increasing humidity.

Northern regions, such as San Juan, while warmer, are still slightly cooler than the southern regions. However, the towns within the Cordillera Central Mountain Range, including places like Aibonito and Comerio, maintain their reputation as cooler retreats, even as the overall temperature of the island surges.

Rainfall in June intensifies, both in terms of frequency and volume. The month sees consistent showers, interspersed with occasional heavy downpours, especially in the afternoons. Coastal areas, from Aguada to Yabucoa, feel the combined effects of heat and rain, resulting in a moist, tropical ambiance typical of Caribbean summers.

Another noteworthy aspect of June is the commencement of the hurricane season. While major hurricanes aren't as prevalent this early in the season, the potential for tropical disturbances and storms is certainly present, adding another dimension to the island's weather dynamics for the month.
