Weather in September
Temperature

For September, the heat index is calculated to be a hot 91.4°F (33°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. 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.
