Weather in April
Temperature
Mawalgama's warmest months, March and April, record an average high-temperature of 31.8°C (89.2°F).Heat index
April's mean heat index is computed to be a blistering 42°C (107.6°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
