Weather in January
Temperature
The onset of January brings an average high-temperature of a still tropical 34.8°C (94.6°F), nearly matching the December temperature. Pehala's average low-temperature of 20.1°C (68.2°F) in January reflects a considerable decline from the daytime peak.Heat index
The heat index for January is computed to be a blazing hot 48°C (118.4°F). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.When referencing the heat index, its values are suitable for shady environments and light breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite 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.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
