Temperature

The average high-temperature in January, at a tropical 30.3°C (86.5°F), reveals a modest deviation from December's 29.7°C (85.5°F). In Kahapola, the average temperature during the nights of January drops to a moderately hot 23.4°C (74.1°F).

Heat index

The heat index value during January is appraised at a sweltering 37°C (98.6°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

UV index

Note: The maximum daily UV index of 7 in January converts into the following recommendations:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
