Weather in September
Temperature
The arrival of September denotes a barely perceptible change in the average high-temperatures to a still warm 29.8°C (85.6°F) from August's 29.6°C (85.3°F). Koupéla reports a consistent average low-temperature of 21.5°C (70.7°F) throughout September nights.Heat index
In September, the heat index is estimated at a very hot 39°C (102.2°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for the ordinary person.Note: In September, a daily UV index of 6 turns into the following recommendations:
Resist extreme sun exposure. Guarding against solar damage is essential. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
