Weather in April
Temperature
April, marked by an average high-temperature of 31.8°C (89.2°F) and a low-temperature of 24.7°C (76.5°F), is the warmest month.Heat index
In April, the heat index is estimated at a fiery hot 38°C (100.4°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
