Weather in September
Temperature

In September, the heat index is evaluated at a tropical 87.8°F (31°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment.
