Know that the heat index computations account for shaded terrains and slight winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. 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 particularly relevant to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.

Humidity

In April, the average relative humidity is 72%.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
