Weather in September
Temperature
As Deerwood Heights transitions from August to September, the average high-temperatures adjust to a warm 85.1°F (29.5°C), nearly the same as the previous 89.4°F (31.9°C). The low-temperature averages to a pleasant 70.9°F (21.6°C) during the nights of September.Heat index
September's mean heat index is computed to be a sweltering 95°F (35°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
