Weather in January
Temperature
With the start of January, Hihifo measures an average high-temperature of a still warm 28.6°C (83.5°F), not significantly differing from December's 28.1°C (82.6°F). An average low-temperature of 27.8°C (82°F), slightly less than the daytime peak, marks the month of January.Heat index
For January, the heat index is estimated at a tropical 33°C (91.4°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Consider that heat index readings are for situations in the shade and light wind. 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 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
