During the winter months, cold fronts called northers sometime blow in reducing visibility. But you can still dive on the leeward sides of the atolls except in rare cases of heavy weather. Visits to the outer atolls generally leave little else to do but dive or snorkel.
Most resorts offer wind-surfing, kayaking and all have great beaches and comfortable hammocks.
