The Lowdown

Alright folks, Rusty here. Let’s break down what’s on the menu for the next couple of weeks.

To be honest, we’re looking at a pretty quiet start. The first few days are a write-off – barely a ripple, and what’s there is messy. You’re looking at a solid gap with nothing worth paddling out for until we get past the first week of September.

The first real chance of something decent shows up on Wednesday, 3rd September. The swell builds to 6ft from the WNW, with a period of 12 seconds, giving the water some real energy (757). The problem is that wind is a solid 35 km/h cross-off. It’ll be clean, but it’s going to be a battle. By the afternoon, it’s pushing 8ft (1820 energy), and that’s getting into the "pro’s only" territory, especially with the same strong wind. For the average punter, this is more of a look-and-see day.

Thursday, 4th September is a big one, but it’s a warning. We’re talking 10ft of WNW swell, with a period of 12-13 seconds and combined energy screaming past 2500. This is massive, powerful, and honestly, too big for White Rocks. The wind is cross-shore and strong. The report actually says it’s too big for this break. If you’re a hellman on a big gun, you might eye it, but for everyone else, this is a day to watch from the cliff. The energy is just too heavy.

Now, here’s the standout. You want to circle Friday, 11th September. This is the one. Morning sees 7ft of WNW swell with a 10-second period, but the wind is a gentle 15 km/h offshore from the south. That’s glassy, clean, and perfect. The energy is a solid 1159 – plenty of punch. By the afternoon, it gets even better: 8ft, 11-second period, still gentle offshore wind, and the energy jumps to 2173. This is excellent, powerful surf for experienced surfers. The sets will be clean, the faces will be steep, and the crowd will be there. This is your session.

The following morning, Saturday, 12th September, is still very good. The swell drops to 6ft from the NW, period still 11 seconds, and the wind is a moderate offshore from the south. Energy is 659. It’s a touch smaller, but still clean and punchy. A great follow-up to the day before.

The water temp is sitting at 60°F, which is pretty average for this time of year – nothing unusual there.

After that, the swell fades fast. By Sunday the 13th, we’re back to small, weak waves and not worth the drive.

So, to sum it up: the first week is a dud. The big one around the 4th is too heavy. The real gold is Friday, 11th September at White Rocks. That’s your best bet. Get it while it’s clean.

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.
