October weather forecast
Puerto Rico, USA

October in Puerto Rico brings a gradual transition as the island starts to inch away from the peak of its wet season. The month experiences temperatures that sway between lows of approximately 76°F (24.4°C) and highs that might climb up to 89°F (31.7°C). Although still warm, there's a subtle dip from the zenith of summer heat experienced in September.

The dichotomy between the northern and southern parts persists, with areas like San Juan, Guaynabo, and Carolina being a shade cooler than their southern counterparts. High-altitude towns within the Cordillera Central Mountain Range, such as Corozal and Aibonito, continue to offer relatively cooler spots, though the contrast with coastal temperatures becomes less prominent as the year progresses.

October's rainfall is noteworthy. Although the trend of clearer mornings followed by afternoon showers remains, the intensity and frequency begin to diminish, hinting at the impending dry season. Coastal regions, encompassing towns from Isabela to Humacao, navigate this transitional phase, experiencing fewer downpours but retaining the moist ambiance.

While October is still part of the hurricane season, the threat starts to decrease. Nonetheless, the remnants of the active September can still influence October's weather, with the possibility of tropical storms or even late-season hurricanes. Preparedness remains essential, even though the peak of the season has passed, as Mother Nature occasionally defies patterns and predictions.
