Weather in September
Temperature
The arrival of September corresponds with a light shift in temperature, down from a hot 94.5°F (34.7°C) in August to a still tropical 88.9°F (31.6°C). Bon Wier's average low-temperature is measured at a pleasant 69.1°F (20.6°C) during September.Heat index
For most parts of September, the heat index is computed to be a blisteringly hot 105.8°F (41°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. 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 highly critical to babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Boost your sun resistance with garments that are densely woven yet spacious. Take to heart! Snow reflection can almost magnify the Sun's UV radiation twofold.
