Weather in September
Temperature
The transition into September marks the average high-temperature at a warm 85.8°F (29.9°C), differing minimally from August's 88.3°F (31.3°C). Throughout September nights, Niceville experiences a consistent temperature average of 74.7°F (23.7°C).Heat index
September's heat index is estimated at a fiery hot 96.8°F (36°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
