Weather in April
Temperature
In Adappankulam, Sri Lanka, the months of March and April are known for the peak temperatures, reaching an average high of 34.3°C (93.7°F).Heat index
April's average heat index is evaluated at a burning hot 51°C (123.8°F). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
