Weather in January
Temperature
Banda Aceh experiences an average high-temperature of a still warm 29°C (84.2°F) in January, subtly different from December's 28.9°C (84°F). Throughout January, Banda Aceh registers a consistent average low-temperature of 23.8°C (74.8°F).Heat index
For most parts of January, the heat index is appraised at a fiery hot 35°C (95°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Shun overexposure. Protection from sun ravages is indispensable. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection. Caution! Sand and water reflections can notably increase the UV radiation intensity.
