Weather in January
Temperature
The transition into January marks the average high-temperature at a still tropical 30.3°C (86.5°F), differing minimally from December's 31.4°C (88.5°F). An average nighttime temperature of 26°C (78.8°F) marks January.Heat index
For most parts of January, the heat index is appraised at a torrid 38°C (100.4°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Observations indicate that the heat index values are for shady locations with light wind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

The months with the highest UV index are January through May, August through December, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.Note: A maximum UV index of 7 in January translates into the following recommendations:
Continue precautions and advocate sun safety advice. Deterrence of sunburn is indispensable. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
