Weather in September
Temperature
The beginning of September brings a slight decrease in the average high-temperature, transitioning from a hot 93.2°F (34°C) in August to a still tropical 87.3°F (30.7°C). A pronounced dip becomes evident during the nights in September as Beirne logs a consistent average temperature of 65.5°F (18.6°C).Heat index
For most parts of September, the heat index is calculated to be a very hot 98.6°F (37°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.In terms of the heat index, values are set with light wind and shade conditions in mind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
