Weather in April
Temperature
Transitioning into April, cầu An Lạc records an average high-temperature of a still torrid 35°C (95°F), almost identical to March's 35.4°C (95.7°F). The average temperature during April nights dips to a warm 26.3°C (79.3°F).Heat index
The heat index value for April is estimated at a life-threatening hot 48°C (118.4°F). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
