Kurugoda, Sri Lanka

Temperature

Kurugoda's shift into April is marked by a subtle change to a still tropical 31.2°C (88.2°F) from March's 31.5°C (88.7°F) in temperature. During April, Kurugoda experiences an average low-temperature of 20.8°C (69.4°F) at night.

Heat index

In April, the average heat index is appraised at an extremely hot 41°C (105.8°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the 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. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

The average relative humidity in April is 79%.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
