Weather in September
Temperature
Guthrie's September weather shows a modest shift in high-temperatures, falling from August's hot 92.8°F (33.8°C) to a warm 84.7°F (29.3°C). During September, the temperature is averaged to a low of 65.5°F (18.6°C) at night.Heat index
September's mean heat index is estimated at a tropical 89.6°F (32°C). Unrelenting activity during exposure could cause fatigue and potentially lead to heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', determines the feeling of heat when you account for the relative humidity. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
