Weather in September
Temperature
In Lotus, entering September brings a subtle temperature decrement, reducing from August's hot 88.3°F (31.3°C) to a warm 82.4°F (28°C). Following the sharp contrast to daytime warmth, an average nighttime temperature of 54.5°F (12.5°C) gets registered during September.Heat index
Throughout September, the heat index is appraised at 82.4°F (28°C). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.The heat index's values are generally associated with conditions in shade and light breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
