Weather in January

During January, Vaitahu observes a subtle ascent to a still moderately hot 27.4°C (81.3°F) from December's 27.2°C (81°F) in the average high-temperature. Vaitahu experiences a steady nighttime temperature of 26.8°C (80.2°F) throughout the month of January.Heat index
The heat index for January is evaluated at a hot 30°C (86°F). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.The standards for the heat index are set for locations in shade and under light breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', quantifies the warmth felt when relative humidity is considered. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
