Weather in April
Temperature
The introduction of April notes a subtle temperature variation to a still warm 27.7°C (81.9°F) from March's 27°C (80.6°F). Rivière-Salée nights in April witness a mild cool down to an average temperature of 25.3°C (77.5°F).Heat index
The heat index for April is estimated at a hot 31°C (87.8°F). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
