Weather in April
Temperature
April's arrival coincides with a subtle temperature rise, moving from March's 23.9°C (75°F) to a still warm 27.4°C (81.3°F). During April, the average low-temperature is a pleasant 22°C (71.6°F).Heat index
The average heat index in April is estimated at a tropical 31°C (87.8°F). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
