Weather in September
Temperature
In September, the average high-temperature marginally decreases from a fiery hot 95.5°F (35.3°C) in August to a tropical 88.3°F (31.3°C). In the month of September, Donie experiences an average low-temperature of 68.9°F (20.5°C).Heat index
September's average heat index is calculated to be a sweltering 100.4°F (38°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
