Weather in April
Temperature
The advent of April sees the average high-temperature at a still warm 29°C (84.2°F), subtly shifted from March's 28.4°C (83.1°F). In Istiqlal, April nights maintain a consistent temperature, with an average low of 24.4°C (75.9°F).Heat index
In April, the average heat index is evaluated at a fiery hot 35°C (95°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. 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 'apparent temperature', arises from combining readings of air temperature and relative moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
