Weather in September
Temperature
With the beginning of September, the average high-temperature shows a small decrease, transitioning from a hot 93.2°F (34°C) in August to a moderately hot 84.6°F (29.2°C). Geary observes an average nighttime low-temperature of 66°F (18.9°C) during the month of September.Heat index
The heat index value for September is computed to be a hot 89.6°F (32°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 are particularly meaningful for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
