Weather in September
Temperature
On the advent of September, Chamen's average high-temperature exhibits a minor adjustment to a still tropical 32°C (89.6°F) from August's 31.5°C (88.7°F). During September, the temperature tends to dip to an average of 24.6°C (76.3°F) at night.Heat index
September's heat index is calculated to be a scorching 44°C (111.2°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Adhere to precautions and respect sun safety doctrines. Avoiding sunburn is vital.
