The low season in the Maldives is between May and October. Although the archipelago experiences increased rainfall, it generally only pours for short periods at a time. It's still warm during these months, but with increased humidity, it can be less comfortable during the drier months, at least until you acclimatise yourself to it.
Being the low season, there are fewer visitors at the resorts, so you can have a more peaceful time while sunbathing and going on the various excursions. That being said, this time is popular with surfers since the area gets bigger waves. In May and June, Maldivians observe the Muslim holy month of Ramadan where they fast during the day, so there may be some restrictions on the local islands.
Being a mostly dry archipelago with sporadic, short thunderstorms even during the wet months, the Maldives is a good place to visit all year. If you visit during the low season, you can enjoy off-peak rates and still get to enjoy what this country has to offer as long as your itinerary isn't packed with a lot of water sports and outdoor activities. Now that you know the best time to visit the Maldives, you can start planning your dream holiday!
