The Lowdown
Righto, let’s have a look at what Rolling Stones has in store for us. It’s a solid reef setup, takes a south swell, and it’s fairly consistent, so when the conditions line up, it can be a proper session.
The water’s sitting at 54°, which is a bit colder than normal for this time of year, so you’ll want a decent suit on.
First up, the start of the week is a write-off. Tuesday the 18th is a mess – strong cross-shore winds, lumpy, and the wave quality is just not there. Wednesday the 19th is the same story, just a lot of energy but blown out. Thursday the 20th is a little cleaner but still marginal, with moderate cross-shore chop. It’s not until Friday morning the 21st that we finally get a proper window. The wind goes light offshore from the northwest, and we’ve got a solid 6ft south swell with a very long 16-second period. The combined energy is pumping at 1581 (moderate to strong). That’s a stand-out session for experienced surfers – clean, powerful, and those long-period lines will be lining up nicely on the reef. Friday afternoon stays clean with a cross-off breeze and 5ft waves, still good but a notch down.
Saturday the 22nd has some smaller clean waves, 4ft in the morning dropping to 3ft in the afternoon, with offshore winds. It’s surfable but ordinary. Sunday the 23rd is tiny and not worth paddling out for.
Then we hit a bit of a flat patch until Wednesday morning the 26th. That’s another beauty – light offshore wind from the northwest again, a solid 6ft south swell with a 15-second period, combined energy of 1386 (moderate to strong). This is a standout for experienced surfers: clean, powerful, and consistent. Wednesday afternoon stays excellent with glassy conditions and 5ft waves. Thursday the 27th is very good too, with moderate offshore wind and 5ft, plus glassy conditions in the afternoon.
After that, it tapers off through the end of August into smaller, weaker swells. But then Monday the 31st of August kicks back in with a 6ft SSW swell and a 14-second period, light offshore wind, and combined energy of 1376. That’s another excellent session for experienced surfers. The afternoon sees a bigger 10ft south swell but with a light cross-shore wind, so it’s more for the brave.
Into September, Tuesday the 1st and Wednesday the 2nd have big 7ft to 10ft south swells with long periods, but the winds are cross-on or light cross-shore, so the quality is marginal. That’s big, powerful surf but not perfect – definitely expert territory if you paddle out.
Overall, the real standouts are Friday the 21st of August and Wednesday the 26th of August. Both have clean offshore winds, solid south swell, and long period. That’s the time to be in the water.

Information about the Rolling Stones Surf forecast
The above surf forecast table for Rolling Stones provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rolling Stones can be found by selecting the local surf guide option on the grey menu. Our Rolling Stones 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 (Rolling Stones) 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 Rolling Stones 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.
Rolling Stones is 48 km (30 miles) from the city of Gisborne. If you plan a holiday in Gisborne and Mahia, look for hotels and other accommodation in Gisborne. Gisborne has rooms for a wide range of budgets as well as car hire and transport links.
