Heat index

In April, the heat index is estimated at a life-threatening hot 49°C (120.2°F). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

The average relative humidity in April is 67%.

Note: The maximum UV index of 7 during April leads to these instructions:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation. Notice! Sand and water reflections contribute to a stronger UV exposure.
