Weather in January
Temperature
The advent of January denotes an average high-temperature of a still tropical 30.6°C (87.1°F), subtly different from December's 31.5°C (88.7°F). Cwa temperatures generally rest at a low of 20.9°C (69.6°F) during the January nights.Heat index
For January, the heat index is computed to be a sweltering 35°C (95°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Realize that the values for the heat index are set for shaded places and light winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period.
