Weather in September
Temperature
Walroy's weather, upon September's arrival, documents an average high-temperature of a still hot 86.7°F (30.4°C), nearly identical to the prior month. Throughout September, Walroy records an average temperature of 70.5°F (21.4°C) at night.Heat index
September's mean heat index is computed to be a very hot 102.2°F (39°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Note that heat index values are valued for light wind and location in the shade. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
