Weather in April
Temperature
In Bobella, Sri Lanka, the average temperatures in April are the highest, with a peak at 34.9°C (94.8°F) and a low of 23.5°C (74.3°F).Heat index
For most parts of April, the heat index is estimated at a burning hot 52°C (125.6°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.Know that the heat index computations account for shaded terrains and slight winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. 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 essentially critical for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
