Weather in September
Temperature
The transition from August to September sees average high-temperatures adjusting to a still hot 31.5°C (88.7°F), from a not significantly different 30.9°C (87.6°F). Crique Anguille's nighttime temperature during September is consistently averaged at a moderately hot 24.5°C (76.1°F).Heat index
In September, the heat index is computed to be an extremely hot 41°C (105.8°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
