Barandal greets September with an average high-temperature of a still moderately hot 29.7°C (85.5°F), marking a slight deviation from the preceding month. During the month of September, the temperature falls to an average of 24°C (75.2°F).

Heat index

For most parts of September, the heat index is calculated to be a very hot 38°C (100.4°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
