Weather in September
Temperature
The advent of September brings a slight shift in average high-temperature, moving from 93.9°F (34.4°C) in August to a still hot 87.3°F (30.7°C). Ogden's nights in September cool down to an average low-temperature of 66.2°F (19°C).Heat index
During September, the heat index is computed to be a very hot 98.6°F (37°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Sunshine

In Ogden, the average daily maximum UV index in September is 6. A UV Index of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV radiation for the ordinary person.Note: A typical high UV index of 6 in September suggests the following recommendations:
Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
