Weather in September
Temperature
The onset of September notes an average high-temperature of a still tropical 86.9°F (30.5°C), subtly shifted from August's 90.1°F (32.3°C). Avon throughout September, records an average low-temperature of 69.6°F (20.9°C).Heat index
For September, the heat index is calculated to be a torrid 98.6°F (37°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
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. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
