Weather in September
Temperature
The advent of September signifies a minor shift to an average high-temperature of a moderately hot 29.8°C (85.6°F), aligning closely with August. Perrelos's nights in September maintain a consistent average of 25.3°C (77.5°F), demonstrating a minimal differential from its daytime temperature.Heat index
For most parts of September, the heat index is calculated to be a fiery hot 36°C (96.8°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Ward off overexposure. Defence against solar harm is crucial. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
