Whilst I'm certainly no expert on the place, I thought it would be a good idea to give a little info on South West Rocks for those thinking of heading up over the spring / summer period.
During the warmer months nor-east winds prevail, providing smooth water in-close, and open bay conditions once you leave the protection of the breakwall. The only real swell to entre the bay is nor-east, but any sizable swell with "east" in it, will usually wrap around the point providing some fun waves to ride or jump.
Windsurfing Trial Bay is all about smooth water in-close and plenty of ramps to get air-borne on as you charge out to deeper water. Essentially it's a bump and jump location, but occasionally has some terrific waves to tear apart. Low tide mid to late afternoon with a 15 knot plus nor-easter is a winning combo, but most tides are sailable and there's effectively no currents to worry about in the sailing zones.
Most windsurfers launch at the old gaol, simply walking their rigged gear down the concrete beach access ramps either near the rock wall or the one closer to the main parking area. Both have grassed rigging areas and town water and showers over-looking the action.
Trial Bay works in any wind from Nor-east, north, nor-west, west, and south-west. Too much south and it's very gusty on offshore.
