The Lowdown
Alright, Rusty here again, giving you the same story but in feet and miles. For White Rocks, it's looking like a slow start.
The first week is pretty disappointing. From Tuesday, August 25th, right through to the end of August, we've got tiny, weak surf. Most of the wave energy readings are in the low double digits (like 39, 17, 8) – that's barely enough for a ripple. Conditions are often messy or blown out. You're better off waiting.
The first real chance comes on Sunday, August 30th, in the morning. Swell is a tiny 4 ft from the NW, but the wind is glassy. For a beginner spot like White Rocks, that is gold. The energy is still low (180), so it's not powerful, but the clean, smooth surface makes it the best option for a fun, easy session. That's your winner for the first week.
Then we get another quiet spell.
The second week picks up the pace. Wednesday, September 3rd brings a proper pulse. The morning and afternoon sees 6 ft to 7 ft from the NW with a 11-second period – that's groundswell. The combined energy jumps to 773 and 935, which is strong. The wind is cross-offshore, so the faces will be clean. For experienced surfers, this is the highlight. The 7 ft is expert territory. For beginners, that 6 ft is pushing the limit. And with that long period, the sets will be bigger and more powerful, but at a beach break, they might close out, so keep your wits about you.
After that, the swell fades back into small, ordinary surf for the rest of the run.
To wrap it up: your top call is Wednesday, September 3rd for the bigger, clean groundswell (not for beginners), and Sunday, August 30th morning for a glassy, small-wave session. The rest is mostly a bust.
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.
