Weather in April
Temperature
The onset of April marks an average high-temperature of a still moderately hot 27.7°C (81.9°F), hardly differing from March's 28.5°C (83.3°F). During the April nights, an average temperature of 18.6°C (65.5°F) is observed.Heat index
The heat index for April is evaluated at a tropical 32°C (89.6°F). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Know that the heat index computations account for shaded terrains and slight winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
