The Lowdown
G’day, Rusty here. Let’s be straight with you—this stretch of the coast is looking pretty grim for a proper paddle. The good news? There are no real standouts, so you’re not missing out on a classic. The bad news? We’ve got a long, flat, and uninviting run ahead. The forecast shows a big empty gap right at the start, with nothing worth paddling out for until we get deep into the window. The first real chance of any surf doesn’t show up until the 28th, and even then, it’s a marginal, cleanup-set kind of deal. The swell energy is weak to non-existent for most of the period, and when we do finally see a pulse of energy, the wind is all over the shop, blowing cross-onshore and chopping things up.
Let’s break it down day by day. From the 14th through the 24th, we’re looking at a whole lot of nothing. Swell heights are mostly under 3 ft, with periods that are short and weak. The energy reading is sitting in the low double digits most days, which is a clear sign of a flat spell. The winds aren’t helping either—mostly cross-onshore or onshore, with a mix of chop and bump. There’s a brief window on the 16th where the wind goes offshore and clean, and we get a little 3 ft NW swell with a short 8-second period. It’s surfable, but honestly, it’s just ordinary. Not worth getting excited about.
Then on the 18th, a real slug of energy shows up—the combined energy jumps to 1384 in the morning and 1783 in the afternoon, with 8 ft of WNW swell. But here’s the kicker: it’s a beach break setup, and the wind is howling from the west at 25 mph, making it a messy, lumpy cross-chop. That’s not a surf forecast; that’s a kite-surfing forecast. Too big for beginners, only for the experts, and even they’ll be scratching their heads. It’s not a goer.
After that, the energy drops off again, and we’re back to dribble. The 19th and 20th have some size but the period is short and the winds are cross-onshore again. The 25th and 26th see a slight bump in period to 10-11 seconds, but the height is tiny, 1 ft to 2 ft, with no push behind it. The energy is in the weak zone, so it’s still a no-go.
Now, the 28th and 29th are the only real hopes in this entire 16-day window. On the 28th, we finally get some proper groundswell with a 14-second period and 4 ft of WNW swell. Energy jumps to 455 and 415. Winds are light and cross-onshore from the NE and NNW, which will keep it semi-clean. It’s nothing epic, but it’s the first time the ocean has any real form. The 29th is a bit better—6 ft of WNW swell with a 12-second period, and the energy pushes up to 819. Winds stay light from the NW. The morning looks better than the afternoon, which is described as marginal. This swell direction is from the WNW, which is close to that NW optimum for White Rocks, so it should wrap in okay. But White Rocks is a beach break, and with that long period groundswell, it can get a little straight and walled. It’s not going to be a barrel fest, but it’s the only real chance you’ll have for a proper paddle.
For the first break we mention, the water temp is 59°F, which is about 1°F warmer than average for this time of year. So, it’s pretty normal—don’t expect a spring suit-free session.
Honestly, this outlook is a bust. The long gap from the 14th to the 27th with no real options is a tough pill to swallow. When we finally get some size on the 29th, it’s still not a standout, just the best of a bad bunch. It’s a long-range call, so treat it with caution. But that’s the honest truth from the data. Stay patient, keep the board waxed, and maybe give the kite a thought for the 18th. That’s all I’ve got.
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.
