Weather in September
Temperature
A mild shift in the average high-temperature occurs in September, reducing from a fiery hot 97.9°F (36.6°C) in August to a tropical 90.5°F (32.5°C). Bruni's average low-temperature during September nights is observed to be a warm 74.1°F (23.4°C).Heat index
The heat index value for September is calculated to be an extremely hot 105.8°F (41°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
