This is the Maldivian summer. The effect of the season change on diving is dramatic. From November onwards the currents begin to flow from the northeast, visibility is superb and there is lots of action in the channels and thilas on the eastern side of the atolls from the sharks and other pelagic species.
Currents tend to be stronger in January and then ease as we move into February. From February the waters calm down and the surface of the sea is undisturbed by any major wind or wave action. The doldrums continue through March and April with easy diving and slack currents. The end of May generally sees the change of monsoon season back to the southwest.
Throughout the northeast season, pelagic species such as shark and jacks are to be found on the current points on the eastern side of the atoll. In addition, there is usually a cornucopia of reef life. Manta rays and whale sharks, however, will only really be found on the west side during the northeast season.
I have been to the Maldives 9 times and it does pay to do your homework. I can tell you with the resorts you get what you pay for…… I have not been there Oct/Nov but look at the advice above for when you decide to go, look at a map to see the resorts in the right areas.
Hope this helps a little
