The Lowdown
G’day, I’m Rusty. Let’s be straight with you – this stretch of the forecast is looking pretty grim for Atlantic Terrace. The finder is showing a whole lot of nothing for the first week and a half. We’re talking about a real dry spell here, with no real surf to get excited about from Friday 21 August right through until the end of the month. There are a few moments where conditions are labelled “surfable but very ordinary,” but honestly, with swell heights barely cracking 3 ft and weak combined energy (mostly under 100), it’s hardly worth paddling out for. The wind is all over the place – cross, cross-off, cross-on – and mostly fresh to moderate, so the surface is rarely clean.
The first hint of anything with a bit more punch comes on Tuesday 1 September. The afternoon sees a bit of a lift in combined energy to 114 (still modest), with a 5 ft SW swell and 6-second period, but the wind is a fresh cross-shore and the conditions are lumpy cross-chop. Not great. Wednesday 2 September morning offers a 4 ft SSW swell, 6-second period, combined energy of 233 (moderate), with clean conditions and a cross-off breeze from the north. That’s probably the most promising window in the whole 16 days – a bit of a standout for the area, but still just a marginal call. The swell direction is SSW, which is not ideal for this exposed SE-facing break, so expect a bit of a closeout feel.
Through the rest of the first week of September, it’s back to small, weak, and choppy. On Friday 4 September, the afternoon has a 6 ft S swell with 7 seconds and combined energy hitting 494, which is strong, but the wind is a moderate cross-onshore, making for poor conditions. That’s too big for beginners and, with the onshore wind, it’s messy and only really for the experienced crew. The water temperature anomaly is about average for the time of year, so no surprises there.
Bottom line: if you’re desperate, Wednesday 2 September morning is your best bet – clean, manageable, but nothing special. Otherwise, this looks like a kite-surfing stretch with the wind and chop. Stay tuned, forecasts can change.

Information about the Atlantic Terrace Surf forecast
The above surf forecast table for Atlantic Terrace provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Atlantic Terrace can be found by selecting the local surf guide option on the grey menu. Our Atlantic Terrace 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 (Atlantic Terrace) 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 Atlantic Terrace 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.
