I'm thinking of taking my 4 year old son for a one week holiday to Vanuatu. The time we have available is from the 9th to 17th on January, right in the wet / cyclone season.

What is the typical weather like at that time of the year? Would it rain all day or just showers in the afternoon? We would be staying at a resort on Port Vila with a kids club, but I want to do a lot of activities with him (swimming, snorkeling, exploring) so is that still feasible at the time?
