The Lowdown
Alright, mate. Rusty here, and I’ve had a good look at what’s coming up for White Rocks over the next couple of weeks. I’ll be straight with you: it’s a quiet start, but there’s a proper pulse of energy later on that’s got my attention.
The first week is pretty lackluster. We’re looking at a long stretch of small, weak swell and average conditions. For the first few days, from Sunday the 16th through to about Tuesday the 25th, the surf is mostly on the small side, under 3ft, and the wind isn’t doing us many favours. It’s not a total washout, but you’d be scratching for a worthwhile wave. The water temperature is sitting at 60°F, which is about 2°F warmer than normal for this time of year – so it’s a touch on the mild side, but nothing wild.
Sunday the 16th morning actually has a small window of clean surf. The swell is only 2ft from the NW with a short period of 8 seconds, so it’s pretty weak, and the combined wave energy is a measly 60. The wind is light offshore from the SSE, so it’ll be glassy. It’s surfable, but ordinary.
The only real standout in this whole outlook happens down the track. Keep your eyes on Saturday the 29th of August. The afternoon session is looking like a proper event. We’ve got a solid 10ft NW swell rolling in with a 12-second period – that’s a proper groundswell. The wave energy is huge at 2036, so it’s going to be pumping with power. The only catch? The wind is cross-shore, so it won’t be perfect, but for a spot like White Rocks that’s exposed to the NW, this is about as big as it gets. Be warned: this is expert-only territory. If you’re not comfortable in waves over 8ft, give it a miss.
Before that, Wednesday the 28th afternoon also shows some promise. A 5ft swell from the WNW with a 12-second period and a moderate cross-offshore wind will keep things clean. The energy is 657, so moderate but solid. It’s a marginal call, but worth a look for the more experienced crew.
Outside of those two windows, expect long gaps of nothing much, especially between the 22nd and the 27th. It’s a lean run, but that last weekend has real potential.
Stay safe out there.
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.
