Weather in September
Temperature
The move into September indicates a slight reduction in the average high-temperature, down from August's tropical 88.3°F (31.3°C) to a warm 81.3°F (27.4°C). Throughout the month of September, Aldwyck expects an average low of 62.6°F (17°C).Heat index
The average heat index in September is computed to be a tropical 86°F (30°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
