Weather in September
Temperature
September implies a gentle temperature shift, with average high-temperatures reducing from August's torrid 97.2°F (36.2°C) to a hot 87.6°F (30.9°C). During September, the temperature tends to dip to an average of 68.9°F (20.5°C) at night.Heat index
During September, the heat index is estimated at a tropical 93.2°F (34°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Humidity
September through December, with an average relative humidity of 56%, are the most humid months.Rainfall
In Haskell, in September, it is raining for 11.5 days, with typically 1.85" (47mm) of accumulated precipitation. Throughout the year, there are 96.8 rainfall days, and 16.42" (417mm) of precipitation is accumulated.Snowfall
In Haskell, snow does not fall in May through October.Daylight
The average length of the day in September is 12h and 22min.On the first day of the month, sunrise is at 7:13 am and sunset at 8:03 pm. On the last day of September, sunrise is at 7:32 am and sunset at 7:24 pm CDT.
Sunshine
In September, the average sunshine is 8.7h.UV index
In Haskell, the average daily maximum UV index in September is 6. A UV Index of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV rays for ordinary individuals.Note: The maximum daily UV index of 6 in September converts into the following recommendations:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
