Weather in September
Temperature
Dongfang starts September with an average high-temperature of a warm 29.5°C (85.1°F), hinting at a minimal fluctuation from August. September nights cool to an average low-temperature of 26.6°C (79.9°F), a marginal decrease from its daytime equivalent.Heat index
The average heat index in September is computed to be a torrid 36°C (96.8°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. Foresee this! The reflection from snow can nearly double the intensity of UV radiation from the Sun.
