Weather in September
Temperature
With the onset of September, Trinity experiences a modest temperature adjustment, with the average high-temperature gently receding from a tropical 87.4°F (30.8°C) in August to a moderately hot 81.3°F (27.4°C). During September, an average low-temperature of 62.1°F (16.7°C) is observed.Heat index
For most parts of September, the heat index is appraised at a hot 86°F (30°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
