The Lowdown
Alright, Rusty again, breaking it down in feet and Fahrenheit for Atlantic Terrace.
The honest truth is the ocean’s been quiet for a while, and it’s not in a hurry to wake up. We’re looking at a long, flat spell. From Saturday the 15th through to Sunday the 23rd, it’s pretty much unsurfable. Swell is tiny, anywhere from 0.3ft to 1ft, with winds blowing cross or onshore, making it a mess. The combined swell energy is just a whisper, barely reaching 16 at its best. You’d be wasting your energy.
We get a quick pulse on Monday the 17th and Tuesday the 18th. Swell jumps to about 2ft to 4ft, and the wind flicks cross-offshore, cleaning the faces right up. The energy climbs to 219 to 227 (moderate wave energy). The catch is the forecast still calls it “marginal surf.” The water temperature is about average for this time of year. Crowds are likely at this spot, as it’s often full.
If you’re looking for a window to get wet, circle Wednesday the 26th morning. Swell is 3ft from the SSW, with a period of 6 seconds. The wind is light and cross-offshore from the WNW, giving you clean, tidy lines. The combined energy is 107 (moderate wave energy). It’s the best of a pretty average bunch. From there, it falls off a cliff again, with poor conditions through to the end of the month. There’s a solid 5-day gap with nothing worth mentioning after the 27th.
It’s a tough run for surfers. Your best chance is the morning of the 26th for some clean, albeit small, waves.

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.
