Palembang experiences its coldest period in January, February and December, averaging a high-temperature of 31.1°C.

Heat index

For most parts of December, the heat index is estimated at a blistering 43°C. Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Adhere to precautions and respect sun safety doctrines. Avoiding sunburn is vital. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
