The arrival of September signals a subtle shift in temperature, down from a tropical 93°F (33.9°C) in August to a moderately hot 84.9°F (29.4°C). The nighttime temperature, during September, averages of 66.4°F (19.1°C).Heat index

If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', offers an insight into how hot it feels when we factor in moisture content. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children.

Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
