Weather in September

Gregory's September average high-temperature settles at a warm 83.3°F (28.5°C), showing a near match with the preceding month. Gregory, in September, witnesses an average low-temperature of 64.6°F (18.1°C).Heat index
The heat index in September is calculated to be a hot 89.6°F (32°C). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.The heat index's values are generally associated with conditions in shade and light breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
