Weather in April
Temperature
April's advent denotes a minor fluctuation in the average high-temperature to a hot 30.8°C (87.4°F) from March's 28.3°C (82.9°F). An average nighttime temperature of 21.2°C (70.2°F) is observed during April.Heat index
For most parts of April, the heat index is appraised at a scorching 40°C (104°F). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.Note that heat index values are valued for light wind and location in the shade. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
