Weather in September
Temperature
As August makes way for September, Nims's average high-temperature eases from a tropical 88.5°F (31.4°C) to a warm 82.9°F (28.3°C). Nims reports an average low-temperature of 63.5°F (17.5°C) during the nights of September.Heat index
September's mean heat index is computed to be a hot 89.6°F (32°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Note that heat index values are valued for light wind and location in the shade. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
