The northeast monsoon blows the wind from South China Sea from November to March and this is the time when the east coast states have heavy rainfall. Sea activities at this time are very much confined and the main activities at this time is usually the maintenance of boats and fishing related equipments as well as kite flying.
The west coast of Aur Island states are influenced by the southwest monsoon that blows the wind from the Straits of Malacca during the months of May to September. The periods between the monsoons are usually marked by heavy rainfall. The mountains have lower temperature range due to their higher altitude and the temperature ranges from 16 °C to 24 °C.
The 1804 naval Battle of Pulo Aura between the British and the French took place in the island's vicinity during the Napoleonic Wars
