We are planning a trip in a week and forecast looks like rain the whole time. Are there things to do when it rains?
As it's the rainy season, rain may last an hour or so, or it could rain all day - the weather bureau often doesn't specify which can be maddening for tourists!
I've been at resorts where it was expected to rain the entire time and it didn't, and I've experienced the opposite. The Island areas tend to be drier than the mainland (Yasawas being the driest).
You can still swim dive and snorkel. Most resorts have a library or board games to play, or they tailor their daily activities for the conditions.
