Alright, grab a coffee and listen up. Rusty here.
Look, I’ve got to be straight with you – the next 16 days are looking pretty grim for a paddle. We’ve got one spot on the radar, White Rocks, and to be honest, it’s not doing much. The overall pattern is flat and uninspiring. There’s a big gap of nothing good until about the 18th of July, and even then it’s messy.
Right now, and through the first week, it’s tiny and weak. On Sunday the 12th, you’re looking at a meagre 1ft from the WNW with a short 8-second period and a cross-shore wind messing it up. The combined swell energy is pathetic at (14) – it’s barely a ripple. Water temp is sitting at 58°F, which is pretty much bang on average for this time of year, so no surprises there.
We get a little pulse around the 18th of July, but don’t get too excited. Saturday morning the 18th shows 4ft from the NNW, still a short period of 6 seconds, but the energy bumps up to (118). The problem? It’s a cross-onshore wind at 12 mph, so it’s going to be choppy and ropy. That afternoon is slightly bigger at 5ft and energy of (199), but again, that wind chops it up. That’s too big for beginners anyway, and with the wind on it, it’s a messy option for anyone.
The only sniff of something half-decent comes late in the run. On Thursday the 23rd of July, we’ve got a 5ft swell from the NW with a 9-second period and energy hitting (405). That’s moderate wave energy, but the wind is a cross-shore at only 9 mph. It’s not clean, but it’s close. The next day, Friday the 24th of July afternoon, the wind finally drops out and goes glassy – NNW at 3 mph – with a 2ft NW swell. The energy is low at (74), but for White Rocks, a glassy session on a knee-to-waist high wave is the best you’re going to get. It’s surfable, but ordinary.
Honestly, there’s no standout here. If you’re desperate, the glassy window on the afternoon of the 24th of July is your only real chance at a clean little wave. But don't expect much.
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.
