Weather in April
Temperature
The height of temperatures is seen during March and April, averaging a high-temperature of 31.8°C (89.2°F).Heat index
For most parts of April, the heat index is estimated at a blistering 42°C (107.6°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 quite important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to 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.
