Weather in October
Temperature
The arrival of October brings an average high-temperature of a still moderately hot 81.3°F (27.4°C), nearly identical to September's 82.4°F (28°C). Wahiawa records a negligible downturn from daytime temperatures, averaging a low of 73.8°F (23.2°C) in the month of October.Heat index
During October, the heat index is appraised at a hot 86°F (30°C). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
