Weather in September
Temperature
Osborn's September reports an average high-temperature of a still tropical 87.1°F (30.6°C), exhibiting a minor difference from August. In September, Osborn records an average nighttime temperature of 67.1°F (19.5°C).Heat index
September's heat index is estimated at a very hot 98.6°F (37°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to 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.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
