Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from 94.6°F (34.8°C) in August to a still tropical 88.5°F (31.4°C). The average low-temperature, in September, in Guynes, is a comfortable 67.3°F (19.6°C).Heat index
September's average heat index is computed to be a fiery hot 102.2°F (39°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. 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.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
