The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the menu at White Rocks over the next couple of weeks.

Right off the bat, I’ve gotta be straight with you – this is a pretty grim stretch. The water’s sitting at 60°F which is a touch warmer than usual for this time of year, but that’s about the only good news. We’ve got a long gap of nothing worthwhile before we see anything even close to rideable.

The first few days are a total write-off. Swell is tiny, mostly under 1ft, with weak energy (10 combined energy) and the odd bit of glassy wind, but there’s just no wave to work with. That’s Sunday the 30th and Monday the 31st. Tuesday the 1st of September and Wednesday the 2nd are the same story – small, weak, and not worth suiting up for.

We finally see a pulse of energy on Thursday the 3rd. Thursday morning shows a 3ft NW swell with a period of 11 seconds, combined energy of 226, and clean cross-off winds. That’s surfable, but nothing to write home about. Thursday afternoon bumps up to 6ft from the WNW with a 12-second period and strong energy (980), but it’s still only marginal – tide could be a factor, and the wind stays clean. Friday the 4th morning brings a bigger 8ft WNW swell with a 13-second period and very strong energy (1805), but the wind is a fresh 35 km/h cross-off – that’s expert-only territory, and even then it’s a dicey call with the power. The afternoon gets blown out with cross-shore winds.

Saturday the 5th and Sunday the 6th drop back down to small, messy swell with cross-shore winds. Not worth your time.

The standout, if you can call it that, comes on Saturday the 12th of September. Saturday afternoon we’ve got a clean 6ft swell from the NW with a 9-second period, combined energy of 589, and light cross-off winds from the WSW at 15 km/h. The guidance says it’s a good quality window, and the break is exposed to the NW with the optimum direction matching. Crowds are listed as “sometimes,” so you might get a bit of company, but it’s not a zoo. Conditions are clean, and the swell is solid enough for a fun session. This is the best of the whole period, but it’s a long way out – treat it as promising but not locked in.

Sunday the 13th morning still has some clean 5ft NW swell, but the afternoon turns cross-on. Beyond that, it fades quickly into tiny, weak leftovers.

So there you have it – a lot of flat and marginal days, with one real window of opportunity on Saturday the 12th. If you’re desperate, keep an eye on that date, but otherwise, maybe give the board a rest.

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.
