April weather forecast
Magammana, Sri Lanka

Temperature

With April's arrival, Magammana notes an average high-temperature of a still hot 30°C (86°F), closely following the trend of the preceding month. In April, Magammana reports a consistent average low-temperature of 21.1°C (70°F) during the nights.

Heat index

In April, the average heat index is appraised at a torrid 39°C (102.2°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Humidity

The average relative humidity in April is 86%.

Prevent overexposure. Protection from the sun's harmful effects is needed. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
