Weather in September
Temperature
Transitioning into September, Bellewood experiences an average high-temperature of a still hot 86.9°F (30.5°C), marking a minor shift from the preceding month. In Bellewood, an average low-temperature of 70.9°F (21.6°C) is recorded during September nights.Heat index
For most parts of September, the heat index is appraised at a very hot 102.2°F (39°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
