While the weather gets wetter, the temperature parameters remain fairly constant, signalling consistent warmth.

Temperature

April's average high-temperature is a still very hot 37.8°C (100°F), maintaining a close comparison with March's 39.5°C (103.1°F). April's nights observe an average temperature of 26.8°C (80.2°F).

Heat index

During April, the heat index is estimated at an extremely hot 44°C (111.2°F). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.
Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. 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 particularly relevant to babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
