Weather in September
Temperature
The dawn of September sees an average high-temperature of a still moderately hot 29.1°C (84.4°F), subtly contrasting with August's 29.3°C (84.7°F). Nan Cotie's average temperature during the nights of September is recorded at a still warm 26.1°C (79°F).Heat index
During September, the heat index is computed to be a torrid 35°C (95°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
