I'm just back from the Maldives about 3 weeks ago and the rainy season was just begining. Just as previous posters have said, the rain comes on suddenly and heavy, but it can be quite fun and it certainly doesn't get cold. The last couple of days of my holiday were a bit cloudy though, so I might not have been too pleased if it was like that all the time. In saying that, I'm not a great one for the sun anyway and a nightime thunder and lightning storm in the Maldives is well worth seeing. The snorkling is great too and the stars in a clear night sky are pretty amazing.
