Heat index

April's average heat index is computed to be a fiery hot 35°C (95°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
