Temperature

The transition from March to April brings an average high-temperature of a still sweltering 38.9°C (102°F), barely different from March's 36.3°C (97.3°F). Throughout April, Arcot acknowledges a distinct difference between its daytime highs and the steady low average of 25.4°C (77.7°F).

Heat index

Throughout April, the heat index is evaluated at a burning hot 54°C (129.2°F). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.
One should consider that heat index numbers are for shaded settings and light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Immediate care is essential; skin and eyes can be harmed in no time without it. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
