Weather in September
Temperature
The commencement of September introduces an average high-temperature of a still hot 87.3°F (30.7°C), closely mirroring the preceding month. Highland experiences an average low-temperature of 68.2°F (20.1°C) in month of September.Heat index
Throughout September, the heat index is appraised at a sweltering 102.2°F (39°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. 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 'real feel' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. 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 particularly relevant to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
