Being a tropical paradise island, Maldives has just about two seasons throughout the year of which one is the summer season and other, the monsoon. During the summer the temperature in the water is about 20 to 25 degrees celsius and is pleasant to swim or dive into. During the monsoon you would not find it dropping down too low, it stays about twenty degrees celsius all the time thus making it quite pleasant. The only thing you will have to worry about are the activities that might get disturbed during the monsoon season but if you are planning for a less expensive trip to the Maldives then travelling during off-peak season is a good idea as the only thing you will have to put up with the lower cost holiday is rainfall and the less clear visibility underwater.
