Weather in September
Temperature
The onset of September marks an average high-temperature of a still hot 86.9°F (30.5°C), hardly differing from August's 88.5°F (31.4°C). Desoto Lakes experiences a nighttime temperature average of 77.4°F (25.2°C) during September.Heat index
September's average heat index is appraised at a very hot 100.4°F (38°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Know that the heat index computations account for shaded terrains and slight winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. As body temperatures escalate without effective heat release, one might face dehydration threats.
