Weather in September
Temperature
September's arrival brings an average high-temperature of a still tropical 33.5°C (92.3°F), slightly deviating from August's 34.6°C (94.3°F). An average temperature of 26.2°C (79.2°F) is recorded during the nights in September.Heat index
For most parts of September, the heat index is computed to be a blistering 44°C (111.2°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', determines the feeling of heat when you account for the relative humidity. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
