Weather in January
Temperature
January registers an average high-temperature of a still tropical 31.8°C (89.2°F), slightly varied from December's 31.1°C (88°F). January's nights observe an average temperature of 21°C (69.8°F).Heat index
For most parts of January, the heat index is calculated to be a torrid 38°C (100.4°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Observations indicate that the heat index values are for shady locations with light wind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

A UV Index value of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV radiation for the average person.Note: In January, the average maximum UV index of 7 translates into the following recommendations:
Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
