Weather in April
Temperature
The arrival of April coincides with an average high-temperature of a still tropical 32°C (89.6°F), indicating a minimal shift from March's 32.1°C (89.8°F). In Ihala Kottaramulla, the average nighttime temperature during April is a warm 26°C (78.8°F).Heat index
For April, the heat index is calculated to be a scorching 43°C (109.4°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. 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 great significance to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
