Weather in September
Temperature
September's onset records a minor alteration in the average high-temperature to a still tropical 86.4°F (30.2°C) from August's 91°F (32.8°C). Winnie experiences a mean temperature of 73.8°F (23.2°C) during September nights.Heat index
The heat index for September is evaluated at a very hot 98.6°F (37°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

The average daily maximum UV index in September is 6. A UV Index of 6 to 7 symbolizes a high health risk from unprotected exposure to Sun's UV rays for the ordinary person.Note: The UV index of 6 in September translates into these instructions:
Shield from overexposure. Defense against sun-related harm is required. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays. Mind this! Nearly twice the UV radiation from the Sun can be reflected by the snow.
