Two options: - Wedge island (Just south of the actual island) if you have a bit of south in the swell. Note it is port tack waveriding. - Gearies (just north of Avalon) if the swell is big enough (which it could be toward the later part of Sunday) and if there is a bit of south in the wind (WSW).
If seabreeze is accurate, I reckon the best wave/wind combo will be Monday morning at Gearies or Avalon (which happens to be next to each other) depending on how much south there is in the wind.
