Weather in April
Temperature
The shift into April reveals an average high-temperature of a hot 30.3°C (86.5°F), closely mirroring March's climate. Throughout the month of April, Sailolof witnesses an average low-temperature of 25°C (77°F).Heat index
April's heat index is computed to be a very hot 39°C (102.2°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes.
