The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at the next couple of weeks at Tamarama Reef.
Right now, there’s not much happening. The first proper surf to write home about won’t show up until Saturday the 30th of August, so we’ve got a long stretch of small, weak, and pretty ordinary conditions ahead. The first week is mostly a write-off, with tiny waves, a lot of cross-shore and onshore winds, and very little energy. The swell is barely registering, with combined energy readings often below 100 (weak). You’d be better off leaving the board at home.
Then, something shifts. Saturday the 30th of August brings a surge of long-period groundswell from the SSE. The swell jumps to 8ft in the morning, with a period of 18 seconds – that’s very long-period energy. The combined energy is enormous, hitting 4887 (very strong). But here’s the catch: the wind is a gentle cross-shore, and the break is a reef. This size and period, combined with a cross-shore, is going to be pretty wild. By the afternoon, it’s even bigger, around 10ft, and the wind turns cross-onshore. This is expert territory only, and even then, the wind direction is a real problem. The energy is immense, but it’s not clean.
The best window, and the standout for the whole period, is actually Monday the 31st of August into Tuesday the 1st of September. On Monday morning, the swell has dropped to a more manageable 4ft from the SSE, with a 12-second period (still a good groundswell). The combined energy is still strong at 829 (moderate-to-strong). The wind is a light cross-offshore from the NNE, which is clean. That’s your best chance for a decent session. The water temperature is around 62°, which is a bit colder than normal for this time of year, so don’t forget a good spring suit.
Tuesday the 1st of September morning is also worth a look. The swell is holding at 4ft from the SSE, with a 10-second period. The energy is moderate at 318. The wind is dead calm, glassy. That’s about as good as it gets for a reef break like this, with clean conditions and a solid, rideable swell. The afternoon blows out again though.
After that, the second week drops off the cliff. By Wednesday the 2nd, we’re back to tiny, weak surf and messy winds. The long-range call on that Monday-Tuesday window is promising, but it’s still a week and a half away, so keep an eye on the forecasts.
Overall, the only real standouts are the Monday the 31st of August morning and Tuesday the 1st of September morning. The rest of the 16 days is a bunch of flat, choppy, or blown-out junk.
Rusty.

Information about the Tamarama Reef Surf forecast
The above surf forecast table for Tamarama Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tamarama Reef can be found by selecting the local surf guide option on the grey menu. Our Tamarama Reef 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 (Tamarama Reef) 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 Tamarama Reef 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.
Tamarama Reef is 4 km (2 miles) from Randwick. If you plan a holiday in Sydney South Coast, look for hotels and other accommodation in Randwick. Randwick has rooms for a wide range of budgets as well as car hire and transport links.
