Weather in September
Temperature
Punta Allen notes an average high-temperature of a still hot 30.9°C (87.6°F) in September, hardly diverging from August. During the nights of September, the average low-temperature holds at a moderately hot 25.9°C (78.6°F).Heat index
For most parts of September, the heat index is appraised at a scorching 40°C (104°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.For clarity, heat index numbers account for light winds and areas under shade. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
