Weather in September
Temperature
The average high-temperature during September is a still tropical 31.6°C (88.9°F), almost matching the conditions of the preceding month. September nights experience a consistent temperature drop to a moderately hot 23.2°C (73.8°F).Heat index
In September, the heat index is estimated at a blazing hot 45°C (113°F). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. 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. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
