Weather in September
Temperature
Caidian's transition into September involves a gentle shift in temperature, receding from a hot 32.8°C (91°F) in August to a warm 28.5°C (83.3°F). Caidian records a consistent low-temperature of 20.3°C (68.5°F) during September nights.Heat index
During September, the heat index is computed to be a tropical 32°C (89.6°F). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. 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 extremely significant for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
