Weather in September
Temperature
The shift into September reveals an average high-temperature of a still tropical 33.5°C (92.3°F), closely mirroring August's climate. September nights reflect a consistent temperature dip to a moderately hot 29.5°C (85.1°F), a slight descent from daytime peaks.Heat index
For most parts of September, the heat index is estimated at a blistering 41°C (105.8°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
