Weather in September

September, the first month of the autumn in Cornerview, is also a hot month, with an average temperature ranging between max 87.4°F (30.8°C) and min 70.5°F (21.4°C).

Temperature

September's onset brings an average high-temperature of a still tropical 87.4°F (30.8°C), showing a minute difference from August's 90.7°F (32.6°C). During the September nights, an average temperature of 70.5°F (21.4°C) is observed.

Heat index

Throughout September, the heat index is evaluated at an extremely hot 104°F (40°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
