Weather in September
Temperature
September is marked by a subtle drop in average high-temperatures, transitioning from a tropical 93°F (33.9°C) in August to a still hot 87.6°F (30.9°C). Amy's nighttime temperatures in September reflect a stark contrast to the day's highs, falling to an average low of 66°F (18.9°C).Heat index
Throughout September, the heat index is calculated to be a fiery hot 100.4°F (38°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Sunshine

In September, the average daily maximum UV index is 6. A UV Index reading of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for the ordinary person.Note: In September, a regular UV index of 6 translates into these guidelines:
Continue precautions and advocate sun safety advice. Deterrence of sunburn is indispensable. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
