The Lowdown
Alright folks, Rusty here. Let’s get into it for White Rocks.
Right off the bat, it’s a slow start. The first few days are a write-off with tiny, weak swell and messy conditions. The water temp is sitting at 60°, which is about a degree warmer than average for this time of year – nothing too wild, just a little bit of a push.
Our first real chance of a wave comes late on Friday the 11th. It’s nothing to write home about – just a 3ft NW swell, but at least the wind is leaning clean. It’s surfable, but very ordinary.
The standout window is Saturday the 12th morning. The swell jumps to 6ft from the NW, with a very long period of 14 seconds. That’s proper groundswell energy, and the combined energy reading is a solid 1304 (moderate-strong). The wind is light and cross-off, so the waves will be clean. This is a good setup for experienced surfers – the long period at a beach/reef spot like White Rocks can make the waves break a bit straight, so the rip bowl might be the go. If you’re a beginner, 6ft will be a bit much.
Sunday the 13th morning is also a good call. Swell is still 5ft from the NW, period 12 seconds, and light cross-off wind. Clean, good energy (614), and a gentler pulse than Saturday. Both morning sessions that weekend are the ones to chase.
After that, the second week gets messy. Monday the 14th has a fresh offshore, but the swell is building and the wind turns cross-on later. Tuesday the 15th is a write-off with strong cross-onshore wind. Wednesday the 16th afternoon sees a huge 12ft NW swell, but the wind is clean – the problem is the swell is too big for this break. That’s one for the experts only, if anyone is brave enough. The energy reading is 3407 (very strong), so it’s pumping, but it’s a dangerous game.
All in all, the clear winner is Saturday the 12th morning, with Sunday the 13th morning as the backup. The rest of the fortnight is filled with either too-small, too-windy, or too-big swells.
Rusty out.

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.
