Weather in September
Temperature
The shift from August to September includes a minor decrease in the average high-temperature, lightly dropping from a hot 89.8°F (32.1°C) to a warm 83.1°F (28.4°C). Despite a significant deviation from daily highs, September sees an average nighttime temperature of 61.2°F (16.2°C).Heat index
During September, the heat index is computed to be 82.4°F (28°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense 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. 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 particularly meaningful for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.

Be careful. Light complexion individuals might get burns in fewer than 30 minutes. Considering the harmful UV rays from the Sun during midday, it's essential to reduce exposure. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
