Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from a tropical 87.3°F (30.7°C) in August to a moderately hot 81.5°F (27.5°C). Throughout the month of September, Van Cleave sees a steady low-temperature average of 62.2°F (16.8°C).Heat index
For September, the heat index is computed to be a tropical 86°F (30°C). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
