Weather in January
Temperature
January's advent notes a subtle adjustment in average high-temperature to a still hot 30.8°C (87.4°F) from December. An average nighttime temperature of 20.8°C (69.4°F) is recorded during January.Heat index
Throughout January, the heat index is computed to be an extremely hot 42°C (107.6°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Heat index determinations are made taking into account the shade and light air movements. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Shield from overexposure. Defense against sun-related harm is required. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
