Weather in April
Temperature
The unfolding of April shows an average high-temperature of a hot 30°C (86°F), indicating a slight variance from March's 29.8°C (85.6°F). April nights cool down to an average low-temperature of 24.6°C (76.3°F).Heat index
During April, the heat index is appraised at a very hot 37°C (98.6°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Note that heat index values are valued for light wind and location in the shade. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
