Heat index

In September, the heat index is estimated at a tropical 93.2°F (34°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
