Christmas Island - Weather

Christmas Island Weather for Sailors

Christmas Island experiences a tropical equatorial climate.  The general climate is pleasant and warm with a tropical rainy season between November and May and a dry season from June to October with occasional showers.

A visit should be avoided during the monsoon season between November and April, however, in the Tradewinds season when the winds stay in the SE, the anchorage is generally very acceptable.

The best time to visit the island is during the south-east trade wind season from April to November, when temperatures and humidity are lower and there is less rain.

Strong and erratic currents are often experienced at Flying Fish Cove.   Northerly and westerly winds that predominate during the north west monsoon season, from November through to May, make conditions very difficult for boats in the Cove.  March is usually the wettest month on the island.

The island normally escapes the tropical storms which affect the seas towards north west Australia. However, heavy downpours are common during the rainy season and often accompanied by thunderstorms.
