Christmas Island has a humid tropical climate. In the period from April to December, the rainy season begins here, which makes it difficult to see the coastal surroundings.

Heavy downpours are frequent here at this time of the year, capable of shedding a hundred millimeters of rain on the ground in ten minutes.

Because of this, morning fogs are frequent in the coastal areas of the island.

In general, the average annual temperature on the island is kept within 25-27 degrees Celsius, and it is quite favorable for tourists visiting the island, who are attracted by diving (the water temperature on the island is almost always in the range of 23-25 ​​degrees) and the opportunity to watch the migration of red crabs.
