Weather in September
Temperature
The transition from August to September brings an average high-temperature of a still hot 86.9°F (30.5°C), barely different from August's 88.9°F (31.6°C). Bayonet Point records an average nighttime low of 75.7°F (24.3°C) in September.Heat index
For September, the heat index is evaluated at a torrid 100.4°F (38°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
