Weather in September
Temperature
The onset of September manifests an average high-temperature of a still hot 86.4°F (30.2°C), demonstrating a minor variation from the preceding month. Throughout September, Samantha encounters an average temperature drop to a comfortable 66.7°F (19.3°C).Heat index
For most parts of September, the heat index is appraised at a torrid 96.8°F (36°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely vital to babies and toddlers. 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.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Safety measures are advised. Light-skinned individuals may experience burns in under half an hour. To guard against the harmful effects of the Sun, minimize exposure during midday. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
