Temperature

With the onset of April, the average high-temperature subtly transitions from a warm 25.5°C (77.9°F) in March to a still moderately hot 29.3°C (84.7°F). In April, the average low-temperature records at an agreeable 21.3°C (70.3°F) during the nights.

Heat index

In April, the heat index is evaluated at a very hot 35°C (95°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
