Weather in September
Temperature
As August transitions into September, Normanna sees a gentle drop in the average high-temperature, transitioning from a fiery hot 95.5°F (35.3°C) to a tropical 90°F (32.2°C). During the nights in September, Normanna experiences a consistent average temperature of 74.1°F (23.4°C).Heat index
The average heat index in September is estimated at a blistering 107.6°F (42°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
