Heat index

April's heat index is computed to be a torrid 39°C (102.2°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Humidity

With an average relative humidity of 84%, April is the most humid month.

Note: The average daily UV index of 6 in April transforms into the following instructions:
Guard against overexposure. Protection from sun-induced harm is essential. 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. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
