September ushers in a retreat of the monsoon in
Nagpur, initiating a transition into the post-monsoon season. The weather starts to dry up, even though sporadic showers continue enhancing the cooling effect. A significant drop in rainfall signifies this from 281mm (11.06") in
August to 183mm (7.2") in September. The temperature remains steady, offering moderate weather conditions. The drop in humidity and the reduction in cloud cover marks the gradual end of the monsoon season off in September.
Temperature
Nagpur marks the start of September with an average high-temperature of a still hot 32.3°C (90.1°F), hinting at a slight fluctuation from August's 30.5°C (86.9°F). September's average low-temperature reading in Nagpur settles at a warm 23.1°C (73.6°F).

Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.
Heat index values are typically calculated for conditions of shade and a light breeze. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Utilize every vital safety procedure. Individuals with light skin may endure burns in less than 5 minutes. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays. Post an outdoor workout or swimming, a broad-spectrum SPF 30+ sunscreen should be applied generously and frequently.
