Weather in January
Temperature
The arrival of January sees an average high-temperature of a still hot 30.6°C (87.1°F), hardly diverging from December's 30.7°C (87.3°F). An average low-temperature of 23.8°C (74.8°F) is recorded during the nights in January.Heat index
January's mean heat index is calculated to be a fiery hot 37°C (98.6°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

January through March and December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for the average person.Note: In January, a daily maximum UV index of 7 leads to the following instructions:
Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
