Weather in September
Temperature
The arrival of September coincides with an average high-temperature of a moderately hot 85.6°F (29.8°C), indicating a minimal shift from August's 91°F (32.8°C). During September, Safford's temperature falls to a steady low-temperature average of 66.4°F (19.1°C).Heat index
September's mean heat index is estimated at 84.2°F (29°C). Unrelenting activity during exposure could cause fatigue and potentially lead to heat cramps.Always consider that heat index estimations are for light winds and places in the shade. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
