The Lowdown
Alright, this is Rusty. Let's get into it.
We are looking at a stretch that starts slow, pretty flat and messy for White Rocks to begin with. Things start to turn a little on Friday afternoon, but it is not until Sunday morning that we start seeing some proper clean lines. The period of light swell and poor conditions through Thursday and most of Friday is a write-off.
The best of the early action kicks off on Saturday the 12th of September. Saturday morning has a moderate 5 ft NW swell rolling in, with a long 12-second period, giving it some real push. The energy is up around 730 (moderate to strong), and while it is borderline for the beginner crew at that size, the wind is cross-off and clean. Saturday afternoon gets chopped, so get on it early.
Sunday the 13th is a strong shout too. The morning has clean 4 ft NW swell and light winds – cross-off, which makes for well-shaped waves. The combined energy is still good at 332 (moderate). Both Sunday sessions look good, but the morning is a real standout for a clean, cruisy session that suits a wide range of ability.
Then we hit a quiet patch through the middle of the week. Monday and Tuesday see the swell drop off, though Tuesday morning is a treat – glassy conditions with a 4 ft WNW groundswell and a very light northerly breeze, making for a super clean look. That is a sleeper session.
The real highlight, though, comes on Wednesday the 23rd of September. This is the one to circle. Wednesday afternoon pulls in a solid 6 ft NW groundswell with a monster 17-second period. That is very long-period energy, and the combined energy is a massive 1683 (very strong). Wind is glassy – dead calm. This is the kind of afternoon that gets the heart pumping. That long period will stack up nicely at this exposed reef setup, making for some hefty, well-shaped sets. This is for experienced surfers only at that size and period.
And just when you think it is over, Thursday the 24th of September morning is predicted to deliver a big 10 ft NW swell with a 14-second period and an energy reading of 2931 (very strong). That is too big for this break – experts only, and even then, it’s a beast. The wind is cross-off, but it is howling at 30 km/h from the SW, so it won’t be perfect.
Water temps are about average for this time of year. For the Sunday 13th session at White Rocks, the water is sitting around seasonal norms.
This break is fairly consistent and gets occasional crowds, so for the standout Wednesday 23rd, expect company – but the quality will make it worth it.
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.
