Weather in April
Temperature
Duncans, Jamaica, experiences a minor change to a still moderately hot 27.9°C (82.2°F) in average high-temperature during April, closely reflecting March. The April nights in Duncans show a slight decrease to a mean low-temperature of 24.8°C (76.6°F).Heat index
During April, the heat index is calculated to be a hot 31°C (87.8°F). With prolonged exposure and constant activity, one might feel exhausted and experience heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
