Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from a torrid 95.5°F (35.3°C) in August to a hot 88.3°F (31.3°C). The nighttime temperature, during September, averages of 71.1°F (21.7°C).Heat index
The heat index value during September is computed to be a very hot 102.2°F (39°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. 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 particularly relevant to babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
