Weather in September
Temperature
September brings an average high-temperature of a still hot 32.3°C (90.1°F), showing a slight difference from August's 30.7°C (87.3°F). During the nights in September, Gomparou observes an average low-temperature of 22.7°C (72.9°F).Heat index
For September, the heat index is calculated to be an extremely hot 44°C (111.2°F). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.Remember that heat index calculations are made for conditions in the shade with light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated 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 body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
