Weather in September
Temperature
Gritney experiences a subtle adjustment in high-temperatures to a still hot 86.9°F (30.5°C) with the onset of September, maintaining near parity with August's 90.1°F (32.3°C). An average nighttime temperature of 70.2°F (21.2°C) is noted in Gritney during the month of September.Heat index
The heat index value for September is computed to be a torrid 100.4°F (38°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. 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 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Deflect overexposure. Sun protection is a necessity. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
