Weather in April
Temperature
The average high-temperature during April registers at a still tropical 31.7°C (89.1°F), closely corresponding to the preceding month. An average nighttime temperature of 24.2°C (75.6°F) is witnessed in Siliau throughout April.Heat index
April's mean heat index is estimated at a blisteringly hot 43°C (109.4°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
