Weather in September
Temperature
A minimal variation is noted in Lillian's average high-temperature at the onset of September, reaching a still hot 88°F (31.1°C) from August's 91.4°F (33°C). In the month of September, the average low-temperature usually rests at a pleasant 72.5°F (22.5°C).Heat index
In September, the heat index is evaluated at a sweltering 102.2°F (39°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Factoring in the heat index, values are geared towards shaded areas with light breezes. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
