Weather in September
Temperature
The arrival of September corresponds with a light shift in temperature, down from a torrid 95.7°F (35.4°C) in August to a hot 87.6°F (30.9°C). The low-temperature average for Lancaster during September stands at an agreeable 69.8°F (21°C).Heat index
September's average heat index is computed to be a very hot 96.8°F (36°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
