Weather in September
Temperature
The introduction of September notes a subtle temperature variation to a still tropical 86.2°F (30.1°C) from August's 90.9°F (32.7°C). Santa Fe's average low-temperature during September nights is observed to be a warm 75°F (23.9°C).Heat index
September's average heat index is calculated to be a fiery hot 98.6°F (37°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes. Observe! Snow reflection can nearly intensify the Sun's UV radiation twofold.
