The Lowdown

Alright folks, Rusty here. Let’s break down what’s cooking at White Rocks over the next couple of weeks.

The big picture is a mix of a serious pulse early in the second week and a lot of junk in between. For the first few days, you’re mostly twiddling your thumbs waiting for something clean.

First real chance to paddle out is Saturday the 5th. Friday’s a write-off—25 mph cross-wind messing up a 8 ft WNW swell. Saturday morning shapes up with a 6 ft NW swell (11 seconds) under a moderate cross-offshore wind out of the WSW. Wave energy is solid (712). Then Saturday afternoon gets even better—wind goes glassy at 3 mph and the swell drops to 5 ft from the NW at 10 seconds. It’ll be clean, but don’t expect pumping barrels. Water temp is 60°, running about a degree above normal for this time of year—pleasant enough.

Sunday the 6th the swell tanks. Down to 2 ft in the morning and 1 ft in the afternoon. Offshore wind from the S keeps it clean, but there’s no push (energy readings of 64 and 31). You’re better off staying dry.

From Monday 7th through Thursday 10th, it’s mostly poor. Monday has a 3 ft W-NW swell with offshore wind in the morning, but the energy is weak (126). Tuesday 8th is the one to circle—but with a big warning. The morning brings a heavy 10 ft NW groundswell with a 13-second period and a combined energy of 2561. That’s a lot of power. A cross-offshore wind from the WSW at 25 mph keeps it clean, but 10 ft at White Rocks is a beast. Experts only—too big for anyone without serious chops. By afternoon the wind swings onshore with rain, turning it into a messy cross-chop. If you’re not charging that morning window, you’ll miss the best of the pulse.

After Tuesday, it fades fast. Wednesday and Thursday drop to 8 ft and smaller with onshore winds. By Friday the 11th, we’re at 3 ft with a short 6-second period and cross-shore breeze—total no-go. Saturday and Sunday stay in the 4 ft range from the NW but cross-onshore winds keep it lumpy.

There’s a spike in period—a 14-second NW groundswell on Monday 14th—but a 28 mph cross-wind will shred any quality. Same deal Tuesday: 4 ft and 13 seconds, but cross-onshore ruin it.

The last few days from Wednesday 16th through Saturday 19th are flat. Swells drop to 4 ft and below, with onshore or light offshore winds. The final Saturday shows a tiny 1.0 ft and a 28 energy reading. Dead.

Your standout is Tuesday morning the 8th of September. That 10 ft NW groundswell with a 13-second period and clean cross-offshore wind is the only serious session on the menu. But it’s not for the faint of heart—strictly for experts. For most folks, the best bet is Saturday the 5th, especially the glassy afternoon with 5 ft from the NW. It won’t blow you away, but it’s the friendliest wave of the whole run.

Keep an eye on the charts—things can change—but right now it’s a long stretch of flat after that Tuesday blast.

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.
