Weather in September
Temperature
In Greenock, the average high-temperature in September slightly decreases from a fiery hot 96.1°F (35.6°C) in August to a tropical 88.5°F (31.4°C). An average low-temperature of 70.5°F (21.4°C) marks the nights throughout September.Heat index
The heat index value during September is evaluated at a torrid 98.6°F (37°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
