Weather in September
Temperature
The dawn of September sees an average high-temperature of a still hot 88°F (31.1°C), subtly contrasting with August's 91.9°F (33.3°C). During September, Cullomburg's temperature falls to a steady low-temperature average of 67.5°F (19.7°C).Heat index
The heat index in September is appraised at a fiery hot 102.2°F (39°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
