The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for White Rocks.
Right off the bat, I gotta be straight with you – it's a real slow start. The first few days are a write-off. We've got a lot of onshore wind and small, weak junk to deal with. It’s gonna be a quiet stretch until we see some life later in the run.
Now, the first real glimmer of hope shows up on Monday morning, August 24th. The swell is about 4 ft out of the NW, and finally, those winds have clocked around to a light SSE breeze which is cross-offshore. That’s clean. This is a groundswell too, with a long 11 second period. This kind of energy (396) will set up some decent lines, though it might be a bit straight for a beach break, but the quality is there for sure. It's the first proper window, so if you can sneak out, this is your best bet for a good session.
Thursday morning, August 28th brings a bump in swell but ugly wind. 22 mph WNW cross-on breeze makes for lumpy, blown-out conditions with about 3 ft of swell. That’s a hard pass for paddling – might be more of a kiter's day if that's your thing. We get a few more of those messy, windy days before the next real standout.
Hold onto your board for Sunday, August 30th. This is the pick of the entire forecast. We've got a solid 7 ft swell out of the NW for the afternoon session, which is a proper size – one for the experienced crew. The wind is a gentle 9 mph SE breeze, making it cross-offshore and glassy. The wave energy is cranking at 809, and a 9 second period on that size will give it some grunt. That’s a very good session on the cards.
The window closes quickly after that. Monday, August 31st morning is surfable with 3 ft from the WNW and a light S offshore, but it’s just ordinary. We then hit another quiet patch running into September.
There is one final event to flag for the bold. Wednesday morning, September 3rd has a big 7 ft NW swell on the charts (energy 1035), but the wind is a messy 12 mph WNW cross-on. For a spot like this, that wind will kill it. It's a marginal call, only for the experts who don't mind a chop.
So, to sum it up: hold tight through the first week, the real action is on Monday August 24th morning for the first clean one, and Sunday August 30th afternoon is the absolute standout. After that, we're looking at a long, quiet spell.
Rusty.

Information about the White Rocks Surf forecast
The above surf forecast table for White Rocks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at White Rocks can be found by selecting the local surf guide option on the grey menu. Our White Rocks surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (White Rocks) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for White Rocks may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
