You will need to get out before the trades hit and within 2 hours of high tide.
They also organise down wind runs at high tide if you are experienced.
If you are after a family fun wave there is a mellow reef out the front of the Inter Continental at Natadola Bay which works in big swells. Natadola would have to rate as one of the prettiest beaches in Fiji and it is off shore in the trade winds. You can hire aboard from the Inter Con and put in a few holes at their championship golf course if the waves are not on!
