Weather in April
Temperature
The coldest months are February through April, with an average high-temperature of 29.9°C (85.8°F).Heat index
In April, the heat index is calculated to be a blistering 40°C (104°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
