Weather in September
Temperature
September is characterized by a slight reduction in average high-temperature, easing from a very hot 97°F (36.1°C) in August to a hot 90.3°F (32.4°C). Peace Valley Harbor experiences a nighttime temperature average of 74.8°F (23.8°C) during September.Heat index
For September, the heat index is computed to be a blisteringly hot 105.8°F (41°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
