September, the first month of the autumn in Zinc, is still a warm month, with temperature in the range of an average high of 81.1°F (27.3°C) and an average low of 59.7°F (15.4°C).Temperature
Start of September brings a slight shift in the average high-temperature, dipping a bit from August's hot 88°F (31.1°C) to a warm 81.1°F (27.3°C). During the nights in September, the temperature averages to a moderate 59.7°F (15.4°C).Heat index
September's average heat index is estimated at a tropical 86°F (30°C). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
