Weather in September

September, the first month of the autumn in Poley, is still a hot month, with an average temperature fluctuating between 87.4°F (30.8°C) and 70.5°F (21.4°C).

Temperature

September begins with an average high-temperature of a still hot 87.4°F (30.8°C), reflecting close similarity to the preceding month. The average low-temperature of 70.5°F (21.4°C) is witnessed in Poley during September.

Heat index

In September, the average heat index is calculated to be a blistering 104°F (40°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
