Weather in September
Temperature
The arrival of September is marked by a minor reduction in average high-temperature, sliding from a fiery hot 95.5°F (35.3°C) in August to a tropical 88.3°F (31.3°C). The temperature dips to an average of 70.2°F (21.2°C) during September nights.Heat index
In September, the average heat index is calculated to be a torrid 100.4°F (38°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
