Heat index

The heat index value for April is estimated at a life-threatening hot 48°C (118.4°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Regarding the heat index, one should be aware it's determined by shaded settings and mild 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 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Humidity

The average relative humidity in April is 69%.

Note: In April, the maximum UV index of 7 transforms into these recommendations:
Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
