Weather in April
Temperature
April's arrival sees a mild rise in the average high-temperature, transitioning from March's warm 26.8°C (80.2°F) to a hot 30.8°C (87.4°F). During the month of April, the temperature falls to an average of 21.8°C (71.2°F).Heat index
For most parts of April, the heat index is evaluated at a sweltering 39°C (102.2°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
