There are definitely seasons here in the Maldives but they're not the same as the 4 seasons you'd get say in Nth America. The seasons are based around the 2 monsoon seasons. The wet monsoon (not always wet) comes from the SW- the wind drives up from the coast of South Africa over the Indian Ocean and takes cooler moister air towards India- and thus the Maldives. It rains more often during this monsoon period (Mid-April through to the start of December). Sometimes the rains pass very quickly (sudden squalls of 5-10mins are common but sometimes the rain sets in for a week or 10 days at a time.
The "dry" monsoon comes from the NE (India) and doesn't pick up a lot of water before it reaches the Maldives- thus it is a dry monsoon. This period (especially Feb/March) is known for its calm dry weather. It can also rain during this time but the storms are usually short-lived.
For more information on the Monsoon try to google nakai, iruvai and hulhangu.

According to the Nakai, from Jan 6-18 it's clear blue skies, but strong winds from the SW. Jan 19-31 is Calm seas and blue skies.
Because this is the NE monsoon- any resort on the south-western side of the atoll should have the calmest weather and seas.
There is a huge range of different hotels- most are expensive. Some are extremely expensive- as in $1000+/night (for the bed). All inclusive hotels exist- definitely the cheaper option. One that I can recommend is Maaya Fushi located in the North Ari Atoll- it's an Italian run resort (everyone speaks English), all inclusive, decent accom, decent food, good vibe, and the diving is sweet.... but... you're not close to the whale shark region which is in the South of the Ari Atoll. I work on a nearby resort ($1000+) Here there is some excellent shark diving, and an impressive manta spot which (on occasion) can have 40 mantas at a time.
In the south, I can recommend DIVA resort. More expensive but it has a good dive center, ideal location for whale sharks. I used to work there and the diving is sweeeeet, with deep reefs full of fish and current, and then the outer reefs have the whale sharks, mantas, eagle rays etc. and better for the experienced diver as they allow you to buddy-up with other divers of ability. (A lot of the expensive resorts are more hand-holding).
So.. Whale Sharks = South Ari Atoll- recommend DIVA, second I recommend Mirihi- close enough to W/S, great house reef.
Cheaper and good = North Ari- recommend Maaya Fushi
