Heat index

In September, the heat index is estimated at a tropical 31°C (87.8°F). Enduring exposure and unrelenting activity might cause a state of weariness, potentially leading to heat cramps.
Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.

Humidity

In Carthage, the average relative humidity in September is 63%.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays. Stay vigilant! UV rays get a boost in intensity due to sand and water reflections.
