Weather in September
Temperature
The onset of September brings a small shift in high-temperatures, falling from a very hot 96.3°F (35.7°C) in August to a hot 88.5°F (31.4°C). Throughout September, Watt's nights cool down to an average of 70.5°F (21.4°C).Heat index
For most parts of September, the heat index is evaluated at a fiery hot 98.6°F (37°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

In September, the rain falls for 11.3 days. Throughout September, 0.87" (22mm) of precipitation is accumulated. In Watt, during the entire year, the rain falls for 102.8 days and collects up to 12.05" (306mm) of precipitation.Snowfall

Sunshine
In September, the average sunshine is 8.6h.UV index
In Watt, the average daily maximum UV index in September is 6. A UV Index reading of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for ordinary individuals.Note: A typical high UV index of 6 in September suggests the following recommendations:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
