Weather in April
Temperature
The unfolding of April shows an average high-temperature of a tropical 30.3°C (86.5°F), indicating a slight variance from March's 29.9°C (85.8°F). April witnesses a minor deviation from daytime peaks, with an average nighttime temperature of 25.6°C (78.1°F).Heat index
The heat index for April is estimated at a fiery hot 38°C (100.4°F). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.Realize that the values for the heat index are set for shaded places and light winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
