Nānākuli's nighttime average temperature in October drops marginally from the daytime highs, settling at a still moderately hot 75.6°F (24.2°C).Heat index
October's heat index is computed to be a hot 86°F (30°C). If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
