The Lowdown
Alright, let’s break it down for the imperial crew. This is Rusty.
The only spot we’ve got here is White Rocks. The 16-day run starts off dead slow. Monday 31 August and Tuesday 1 September are a dud – small, short-period slop with messy cross breezes. Waves barely push 4 ft. Not worth wetting the suit.
Wednesday and Thursday stay quiet – clean but tiny, only 1 ft to 2 ft. Nothing to ride.
Then Friday 4 September jumps up to 8 ft in the morning from the NW with a 13-second period and solid combined energy (1783). That’s a real groundswell, but as soon as the afternoon hits, the wind cranks hard cross-shore and trashes it. The morning might have a window for experienced surfers, but it’s borderline.
The real standout is Saturday 5 September. Morning delivers 5 ft from the NW with an 11-second period and combined energy of 615 – solid. Wind is a light cross-offshore at 9 mph, so the surface is glassy. This is the pick of the run: good shape, clean, decent size. Afternoon drops to 5 ft but stays clean. Still a good session, but morning is king.
Sunday 6 September drops back to 3 ft – clean but tiny.
Second week: Monday 8 September afternoon bumps up to 5 ft from the NW with a fresh offshore wind (19 mph) and clean conditions. Rideable, but not special.
The big one hits Monday 15 September. Tuesday morning shows 13 ft from the WNW with a 13-second period and massive combined energy (8460). That’s a monster groundswell. But White Rocks is going to be maxed out – the report itself says it’s too big for this break. Only absolute experts should even think about it. Afternoon drops to 10 ft – still huge, still expert-only. Offshore winds keep it looking clean, but it’s a beast.
Bottom line: Saturday 5 September morning is your session. Clean, 5 ft NW swell, nice period, light wind. Everything else is either too small, too windy, or way too big.
White Rocks can get crowded, so paddle out early on that Saturday.
Water temp is about 60°F, just a degree warmer than normal for this time of year – nothing crazy.
If you’re a hard-charging expert, the mid-September swell is there, but it’s serious stuff.
No other breaks in this region, so make the most of that Saturday.
Take care of yourself out there.
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.
