Weather in September
Temperature
The ushering in of September brings an average high-temperature of a still moderately hot 28.5°C (83.3°F), closely mirroring the 26°C (78.8°F) of August. Águas de São Pedro's average low-temperature of 16.2°C (61.2°F) in September reflects a significant disparity from the daytime highs.Heat index
The heat index value during September is calculated to be a hot 31°C (87.8°F). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Note that heat index values are valued for light wind and location in the shade. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. 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. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
