Weather in September
Temperature
September's arrival subtly correlates with a reduction in the average high-temperature, down from a torrid 95.2°F (35.1°C) in August to a hot 86.9°F (30.5°C). Hamilton's nighttime temperature during September is consistently averaged at a pleasant 69.3°F (20.7°C).Heat index
In September, the heat index is calculated to be a sweltering 95°F (35°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
