Weather in October
Temperature
In October, Nānākuli's weather conditions record an average high-temperature of a still moderately hot 81.1°F (27.3°C), demonstrating little divergence from the preceding month. October sees a slight dip to an average low temperature of 75.6°F (24.2°C) from the daytime highs.Heat index
The heat index value during October is evaluated at a tropical 86°F (30°C). If one remains active during constant exposure, it might cause exhaustion and heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
