Weather in September
Temperature
September notes an average high-temperature of a moderately hot 85.8°F (29.9°C), subtly differing from August's 87.4°F (30.8°C). An average low-temperature of 76.8°F (24.9°C) is witnessed throughout the month of September, a mere drop from the daytime peak.Heat index
Throughout September, the heat index is calculated to be a very hot 98.6°F (37°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Shield from overexposure. Defense against sun-related harm is required. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat. Notice! Sand and water reflections contribute to a stronger UV exposure.
