Weather in April
Temperature
With an average high-temperature of 31.4°C (88.5°F) and an average low-temperature of 27°C (80.6°F), April is the warmest month.Heat index
Throughout April, the heat index is estimated at a blisteringly hot 41°C (105.8°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for 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 human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
