The start of September comes with a small reduction in the average high-temperature, subtly receding from a tropical 32.3°C (90.1°F) in August to a moderately hot 27.5°C (81.5°F). A striking departure from daytime highs to an average low-temperature of 15.4°C (59.7°F) is witnessed during September.Heat index

If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.One should consider that heat index numbers are for shaded settings and light wind. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones often underestimate the need for rest and rehydration.
