Weather in September
Temperature
Penelope's weather subtly changes with the onset of September, barely falling from a torrid 95.5°F (35.3°C) in August to a tropical 88.3°F (31.3°C). During September, Penelope records a consistent average nighttime temperature of 70.2°F (21.2°C).Heat index
The heat index value for September is evaluated at a sweltering 98.6°F (37°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
