Weather in September
Temperature
An average high-temperature of a still tropical 87.1°F (30.6°C) marks September, exhibiting a close resemblance to the conditions in August. Throughout September, Archibald's nights cool down to an average of 68.2°F (20.1°C).Heat index
September's heat index is estimated at a very hot 98.6°F (37°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
