The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for White Rocks.
Honestly, mate, it's a bit of a flat spell for the next week and a half. The first ten days or so are just a write-off for any kind of decent surf. We're talkin' tiny dribbles of swell, barely enough to get a beginner wet. You'll see a bit of a bump on the 25th of July, but even that's a long way off and nothin' to get too excited about.
For the first few days, from the 15th through to the 24th, it's mostly poor surf conditions. The swell is tiny, under 3 ft, and the period is short and weak. The wind is a bit of a story too, mostly cross-on or onshore, making it messy. There's a few glassy moments on the 16th morning and the 23rd morning, but with next to no swell, it's a lake. The combined energy is just pathetic, stuck in the double digits, like 5 or 13, which is barely a ripple.
The only real pulse of energy comes in on Saturday the 25th of July. The morning brings a cleaner look with a cross-off breeze and a 6 ft swell from the NNW, but that's getting up there for a beginner. The wave energy jumps to 319, which is a healthy kick. The afternoon is a marginal call, with a drop to 4 ft and a bit of rain, but still clean.
If you're a beginner, the 25th morning might be a bit too much. For the more experienced crew, it could be the only window that's worth paddling out for. The 27th and 28th look similar, but with more onshore wind, killing the quality.
So, the standout is the morning of Saturday the 25th of July. It's the only time the swell height and wind alignment come together for a clean session. Don't expect a classic, but it's the best of a pretty quiet bunch. The water temp is about average for the time of year, nothing unusual.
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.
