April weather forecast
Madurai, India

April stands as an outlier among the early months of the year with temperatures counting among the highest and a substantial rainfall of 32mm (1.26"). Increasing from the previous month, temperatures frequently reach 37.4°C (99.3°F) during the day. It's not uncommon to notice a slight haze over the city due to high humidity levels coupled with rising temperatures. A significant increase in rainfall days suggests a more humid atmosphere and the beginning of pre-monsoon showers. Despite these changes, sunlight remains abundant ensuring a relative balance in the weather.

Heat index

In April, the average heat index is appraised at a life-threatening hot 48°C (118.4°F). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.
Realize that the values for the heat index are set for shaded places and light winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
