April weather forecast
Puerto Rico, USA

As April unfolds, Puerto Rico witnesses the true transitional nature of this month, marking the latter stages of the dry season while welcoming the initial inklings of the wet season. Temperature-wise, the island sees a subtle rise with lows averaging 74°F (23.3°C) and highs touching 87°F (30.6°C). This temperature shift from March is minimal but signals the approach of the tropical summer months.

The geographical dynamics play out consistently: cities in the north, including San Juan, experience cooler temperatures compared to the southern coastal areas. However, it's the high-altitude towns within the Cordillera Central Mountain Range, such as Aibonito and Adjuntas, that continue to boast more moderate temperatures, offering a refreshing contrast to the island's warmer locales.

Compared to March, April presents a noticeable increase in rainfall frequency. While the month doesn't usher in the peak of the wet season, sporadic showers become more regular, hinting at the imminent months of heightened precipitation. Coastal regions, such as Carolina and Cabo Rojo, while experiencing an uptick in warmth, also begin to see intermittent rain events, indicating the island's gradual shift into its tropical rainforest climate.
