Heat index

In March, the heat index is estimated at a hot 31°C (87.8°F). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.
Heat index determinations are made taking into account the shade and light air movements. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
