Weather in September
Temperature
Campbell measures an average high-temperature of a still tropical 88.7°F (31.5°C) in September, nearly consistent with the preceding month. Throughout the month of September, Campbell witnesses an average low-temperature of 67.3°F (19.6°C).Heat index
During September, the heat index is calculated to be a blisteringly hot 104°F (40°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
