The Lowdown
Alright, folks, Rusty here. Let’s chew the fat on what’s heading for White Rocks.
The first bit is a dud. Saturday, September 12th is a total no-go with rain, a lumpy cross-off breeze, and a sloppy 1.6m NW swell. Not a chance. Things clean up on Sunday the 13th. That’s the first real chance: a clean 4ft NW groundswell (11-second period) with sweet 6 mph offshore breezes from the SSW. The combined energy is moderate (297), and crowds are only a ‘sometimes’ deal. Perfect for beginners and a good fun wave.
Monday the 14th still has clean, glassy offshore winds, but the swell plummets to a weak 2ft. It’s surfable, but nothing to write home about.
Then the window slams shut for a long stretch. From Tuesday the 15th right through till Wednesday the 23rd, it’s mostly a mess – fresh winds, cross-shore chop, and poor conditions. There’s a big spike of swell on the 17th and 18th (up to 8ft from the NW, 13-second period), but it’s accompanied by howling 19 mph westerly winds making it a choppy, dangerous affair for experts only.
The absolute standout is Wednesday the 23rd, in the afternoon. We’ve got a solid 8ft NW swell (12-second period) and a light offshore breeze from the SE at just 6 mph. The combined energy is a strong 1621. The data calls it excellent for experienced surfers. That’s your day. It’s a powerful, clean groundswell on the reef, so expect well-spaced sets. At this size (over 8ft), it’s for the pros only.
One last note: the 27th shows a massive 10ft NW swell on the horizon, but it’s flagged as too big for this break.
So, to wrap it up: get wet Sunday the 13th, and lock in Wednesday the 23rd for a serious, memorable session.
Stay stoked.

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.
