Weather in September
Temperature
September witnesses a gentle descent in average high-temperature, descending from August's very hot 95.2°F (35.1°C) to a tropical 86.9°F (30.5°C). Carlton observes an average nighttime low-temperature of 69.3°F (20.7°C) during the month of September.Heat index
The average heat index in September is estimated at a fiery hot 95°F (35°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Observations indicate that the heat index values are for shady locations with light wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
