Weather in January
Temperature
Banda Aceh's January average high-temperature settles at a still warm 29°C (84.2°F), showing a near match with the preceding month. Banda Aceh witnesses an average low-temperature of 23.8°C (74.8°F) throughout the month of January.Heat index
January's heat index is calculated to be a torrid 35°C (95°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Always opt for UVA and UVB-resistant sunglasses on radiant days. Watch out! Reflections from sand and water can surge UV radiation exposure.
