Weather in September
Temperature
September's commencement is accompanied by an average high-temperature of a still warm 29.3°C (84.7°F), diverging marginally from August's 29.7°C (85.5°F). September nights in Bassin-Bleu reflect a consistent temperature dip to a still moderately hot 25.3°C (77.5°F), a slight descent from daytime peaks.Heat index
September's heat index is calculated to be a very hot 35°C (95°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
