Weather in September
Temperature
September brings a marginal elevation to a still tropical 87.1°F (30.6°C) from August's 90.9°F (32.7°C) in Clover Hill's average high-temperatures. During September nights, Clover Hill records an average temperature of 67.6°F (19.8°C).Heat index
In September, the heat index is estimated at a sweltering 100.4°F (38°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Skirt overexposure. People with light complexions might get scorched in under 20 minutes. 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. Experience reduced UV exposure by about half when donning a wide-brim hat.
