The Lowdown
Alright, Rusty here again, this time in feet and knots.
So, Atlantic Terrace is looking like a tough stretch. The water is a chilly 66°, which is a solid 5° colder than usual for this time of year – that’s a proper cold snap, so you’ll want a thick suit.
The first week is pretty much a write-off. We’ve got a pulse of south swell pushing through from the 21st to the 23rd, with heights around 5 to 6 feet, but the wind is just all wrong. Strong SSW and SW cross-shore winds are going to wreck any chance of a clean face. The combined swell energy is moderate (191 to 588), but it’s wasted with that lumpy, cross-chop. By the 24th, the swell drops right off to 2 feet and the energy fades to weak (84). That run of poor conditions stretches all the way through to the 28th of July. The only thing that might catch your eye is the afternoon of the 28th. The wind swings to a light cross-offshore from the west, and the swell is 5 feet from the south. The energy is moderate (356), and it’s looking clean. But it’s only a 1/10 score, so it’s still marginal—maybe a longboard session if you’re desperate.
Then we get a little window on the 29th of July. The morning shows a 3 foot south swell with a moderate offshore wind from the northwest. That’s clean, and the energy is weak (109) but it’s surfable. The afternoon improves a touch, with a 4 foot SSE swell, a bit longer period, and a cross-offshore breeze; the energy picks up to moderate (200). This is the closest thing to a standout in the whole outlook, but it’s still nothing to write home about.
After that, it’s back to the doldrums. From the 30th of July right through to the 5th of August, the swell drops to knee-high or smaller, with weak energy (down to 16 by the 5th). The wind is mostly onshore or cross-shore, and the conditions are just poor. It’s a long gap of flat, messy water.
So, to wrap it up: there’s no real hero session here. The best bet is the morning of the 29th of July if you want a few clean, small waves on a longboard. For the rest of the two weeks, you’re better off doing something else.
Rusty.

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.
