Heat index

The heat index for April is calculated to be a very hot 36°C (96.8°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle 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 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
