Weather in September
Temperature
At the onset of September, Winnie records an average high-temperature of a still tropical 86.4°F (30.2°C), showing little deviation from the preceding month. During September, Winnie observes a consistent average nighttime temperature of 73.8°F (23.2°C).Heat index
The average heat index in September is estimated at a fiery hot 98.6°F (37°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel 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. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Resist overexposure. Safeguarding from solar damage is indispensable. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage. Stay alert! Snow's reflective properties can almost double the UV radiation from the Sun.
