Weather in September
Temperature
With the start of September, Jay measures an average high-temperature of a still tropical 86.7°F (30.4°C), not significantly differing from August's 89.1°F (31.7°C). In Jay, the average low-temperature during the month of September is a warm 73.6°F (23.1°C).Heat index
September's mean heat index is evaluated at a sweltering 100.4°F (38°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
