Weather in October
Temperature
Ewa's average high-temperature marks a still moderately hot 81.1°F (27.3°C) with the advent of October, closely mirroring that of the preceding month. Throughout October, Ewa's nights experience a slight temperature dip to a still moderately hot 76.1°F (24.5°C).Heat index
Throughout October, the heat index is evaluated at a tropical 86°F (30°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes.
