One of my contingency plans when visiting the Maldives is to go in the dry season to minimise the risk of rain (I will be there next month). But not everyone can travel then plus it can be a little more expensive.
If you plan a trip in the rainy season, consider choosing a resort that has an amazing Day Spa like this one. The storm was on its way so I headed indoors and overwater for a relaxing spa treatment ... resurfaced two hours later and the sun was shining again !.
☁️ My other tip is to choose a larger resort that has more activities and places to eat and drink. At least that way you can have a change of scenery. Personally, I prefer smaller, more exclusive resorts but options can be limited on those islands if the weather is terrible day after day.
Last quick tip .. when it’s raining go for a swim (unless there is lightning) ... everything comes to life under the sea and there is something exhilarating about swimming in the rain. I love it !
Added bonus is that the water takes on a fluorescent glow after the rain ... perfect for photos !
