Weather in September
Temperature
The beginning of September records an average high-temperature of a still tropical 86.5°F (30.3°C), almost echoing the conditions of the previous month. Holy Trinity observes an average nighttime low-temperature of 68.2°F (20.1°C) during the month of September.Heat index
For most parts of September, the heat index is estimated at a sweltering 96.8°F (36°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. 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 especially vital to children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
