Weather in September
Temperature
The arrival of September sees a recorded average high-temperature of a still hot 31.4°C (88.5°F), showing little divergence from the previous month's conditions. During September nights, Trentham Park records an average temperature of 23.3°C (73.9°F).Heat index
September's heat index is estimated at a blisteringly hot 42°C (107.6°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Given the heat index, its values are aligned with shaded sites and gentle winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. 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. Rising body temperatures due to excess heat retention could signify impending heat disorders.
