Weather in September
Temperature
The advent of September brings a slight shift in average high-temperature, moving from a fiery hot 96.3°F (35.7°C) in August to a tropical 89.1°F (31.7°C). Nighttime temperatures consistently average a pleasant 69.3°F (20.7°C) during September.Heat index
Throughout September, the heat index is evaluated at a scorching 104°F (40°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Exercise precautions and adapt sun safety practices. Defence against skin and eye affliction is paramount. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
