The climate of Arima
Arima, nestled in Trinidad and Tobago, operates within the substantial domain of the Tropical monsoon climate, designated as 'Am' under the Köppen climate classification. This classification indicates a prevailing weather window marked by substantial rain and high temperatures, without any distinct dry season. Arima doesn't hold back from this template, delivering cherishing warmth round the calendar. A gentle tour through the climate numbers confirms this, revealing a typical temperature arena oscillating between 24.8°C (76.6°F) and 30.1°C (86.2°F).
Scale of warmth doesn't see significant shifts through the year. The year initiates with the lowest average minimal temperature of 24.8°C (76.6°F) in January, ramps up by 1.7°C (35.1°F) to saturate at 26.5°C (79.7°F) in September, before bowing back down to 25.5°C (77.9°F) in December. An equivalent pattern is evident in average high temperatures. Starting from 27.9°C (82.2°F) in January, high temperatures truck along a gentle slope with calculated increments to peak at 30.1°C (86.2°F) in September. Post-September, it's a gentle cool-off, with the year signing off at 28.5°C (83.3°F) in December.
Rainfall, too, has its part to play. Monsoon influence is quite pronounced with rainfall moving between 14mm (0.55") in February, a sharp hike to 115mm (4.53") in October, and then a decline to 44mm (1.73") by December. Not just quantity, the frequency of rain is a significant factor. Rainfall days vary between 10.3 in February to an astounding 22.2 in August. With a UV index keeping a steady hold at 7 throughout the year, accompanied by visibility at a constant 10km (6.2mi), weather remains largely predictable.
