Weather in September
Temperature
The onset of September results in a decrease in the average high-temperature, receding from a tropical 94.6°F (34.8°C) in August to a warm 85.5°F (29.7°C). In September, the recorded average low-temperature in Apache is a refreshing 66.2°F (19°C).Heat index
Throughout September, the heat index is evaluated at a tropical 91.4°F (33°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to 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.
