Weather in September
Temperature
As Alexishafen transitions into September, the average high-temperature stands at a still moderately hot 29.2°C (84.6°F), offering little variation from the preceding month. Throughout the month of September, Alexishafen witnesses an average temperature of 23.4°C (74.1°F).Heat index
September's heat index is estimated at a very hot 35°C (95°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. 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. 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 children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
Humidity
The months with the lowest humidity are July through October, with an average relative humidity of 77%.Rainfall
September is the month with the least rainfall. Rain falls for 22.6 days and accumulates 80mm (3.15") of precipitation.Daylight

Sunshine

April through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV radiation for the ordinary person.Note: The daily high UV index of 7 in September translates into this advice:
Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
