Weather in September
Temperature
The transition from August to September sees average high-temperatures adjusting to a still moderately hot 28.8°C (83.8°F), from a not significantly different 28.4°C (83.1°F). During September, an average low-temperature of 19.3°C (66.7°F) is observed.Heat index
September's average heat index is calculated to be a torrid 35°C (95°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Put precautions into practice - Ensuring skin and eye safety is a necessity. UV radiation is strongest from the Sun during midday; protect yourself by staying in shaded areas. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
