Running this website I’ve honestly read many thousands of Maldives resort reviews to gather research for these articles, and it’s extremely rare to find reviews that mention how the weather ruined a trip. Again, it’s almost the exact same temperature every day of the year, and the rain storms are almost always very short and they have some benefits. Still, before you book I recommend reading as many reviews as you can for the specific resort you have in mind for the time period you are considering.
As mentioned at the top of this article, the Maldives islands stretch out for around 1,000 kilometers north to south, and the weather patterns can vary at least a bit at the extremes. If you read 20 or 30 reviews from those who stayed at that resort in the same month the year or two you are planning on going, and none of them mention bad weather, you are pretty safe. But if many of those reviews mention long rainy periods that disrupted their fun, you might want to check other resorts or other dates.
Agoda.com is the cheapest booking site for most Maldives resorts and they have a great number of reliable reviews. But TripAdvisor has no shortage of reviews and they tend to be longer and more detailed. Better still, you can type in the month you are planning as a keyword and it will only show the reviews that mention that month. It’s a pretty fast way of seeing how previous guests felt during that month in recent years, and chances are you’ll discover that almost everyone mentions pleasant sunny weather for nearly their whole stay.
