The Lowdown
Alright, folks, let’s talk about what’s shaping up for White Rocks. This is a bit of a mixed bag over the next couple of weeks, so let’s get into it.
First up, Thursday morning the 3rd is a bit of a non-starter. We’ve got small, weak swell – only 2ft from the WNW with a short period of 7 seconds. The energy is basically nothing (40), and the wind is a cross-offshore, so it’s clean, but there’s just no power to work with. The water temp is sitting at 60°, which is about a degree warmer than usual for this time of year, so it’s a touch above average.
Friday the 4th sees a big jump in size, with 8ft swell from the WNW, but the period is a solid 12 seconds, which is nice and long. However, the wind is howling at 22-25 mph, creating a messy cross-chop. The energy is massive (1964), so there’s plenty of power, but the conditions are just too rough for a good paddle. This one is for the experts only, or maybe the kite crew.
Saturday the 5th brings a bit of hope. The morning has 5ft from the NW (11 seconds) and a cross-off breeze, but it’s still a bit messy. The real standout is Saturday afternoon: the swell drops to 4ft, still from the NW, but the wind swings offshore from the SSW at only 6 mph. The energy is moderate (309), and the conditions are clean. This is your best bet for the first week – a fun, manageable wave with clean faces.
Sunday the 6th is a dud, with the swell collapsing to 1ft, so don’t bother.
The next real highlight doesn’t come until the following Saturday, the 12th of September. The morning sees a solid 8ft NW swell with a very long 13-second period, and the wind is light offshore from the south. The energy is pumping (2241), and the conditions are clean. This is excellent for experienced surfers, but that size and long period might make it a bit straight for a beach break. The afternoon holds at 7ft with similar clean conditions, so it’s a good day all around.
Sunday the 13th is a nice recovery day, with the swell dropping to 3ft and glassy conditions in the morning. A perfect little clean-up session for the less experienced.
After that, the second week trails off into small, ordinary surf with mostly cross-off winds, but nothing worth getting excited about. There’s a pulse of 7ft on Friday the 18th, but the wind is a strong cross-shore mess, so it’s not recommended.
Overall, the standout is Saturday afternoon the 5th for a fun, clean session, and the big highlight is Saturday the 12th for the experienced crew looking for some power. The middle of the second week has a few days of small, clean waves, but nothing special.

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.
