Weather in September
Temperature
The shift from August to September is characterized by an average high-temperature of a still tropical 87.3°F (30.7°C), not significantly different from the 90.7°F (32.6°C) of August. The average low-temperature, in September, is an agreeable 68.7°F (20.4°C).Heat index
The heat index value during September is calculated to be a very hot 100.4°F (38°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.The standards for the heat index are set for locations in shade and under light breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
Humidity
In Gantt, the average relative humidity in September is 74%.Rainfall
The months with the least rainfall are March, September and November Rain falls for 12.1 days and accumulates 0.75" (19mm) of rain.Snowfall
March through November are months without snowfall.Daylight
The average length of the day in September is 12h and 21min.On the first day of the month, sunrise is at 6:22 am and sunset at 7:09 pm. On the last day of September, sunrise is at 6:39 am and sunset at 6:31 pm CDT.
Sunshine
The average sunshine in September is 8.9h.UV index
In Gantt, the average daily maximum UV index in September is 6. A UV Index of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for the average person.Note: In September, the UV index of 6 transforms into the following advice:
Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
