Heat index

The average heat index in April is calculated to be a life-threatening hot 48°C (118.4°F). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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 body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. 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. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Humidity

The average relative humidity in April is 64%.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
