The Lowdown
Alright folks, Rusty here. Let’s get straight into it for the local outlook.
Well, to be honest, it’s a pretty grim stretch ahead for the next 16 days. We’re looking at Perelle Bay, a reef setup that’s inconsistent and really only for the advanced crew. The water’s running a touch warmer than normal for the time of year here, sitting at 63°, which is a bit of a novelty but not much else to get excited about.
Right now, and through the first week, the story is tiny. We’re talking ankle-snappers to knee-high at best, with swell heights barely scraping 1ft. The combined energy is weak, coming in at just 33. That’s not enough to push a leaf. Winds are mostly cross or cross-off from the ENE and NE, with a fresh breeze blowing on Wednesday morning, but the swell is just too small to bother with. A bit of glassy calm shows up on the morning of Monday the 20th, but with only 0.7ft on the cards, it’s a flat spell, not a surf session.
We then hit a long gap of several days with no real surf. The swell direction tries to shift to the WNW around the 21st, but we’re still stuck with tiny, 1ft waves and weak energy. It’s a waiting game.
The only real standout – and I use that word lightly – lands on the morning of Thursday, 30th July. We finally see a bump of swell from the W, pushing 5ft, and the combined energy climbs to 158, which is moderate. The catch? The period is a short, snappy 6 seconds, so it’s going to be a bit crumbly and disorganised. The wind is a light cross-onshore, so it’ll be a little bumpy, but for the first time in two weeks, there’s actually some water moving. It’s not a gem, but it’s the only thing on the menu. For experienced surfers only, as it’s still a shallow reef, and the crowds are possible here.
Honestly, with the poor quality and consistent small swell, it’s looking more like a kiting spot than a paddling one for the majority of this period. The setup is a beach-and-reef mix, and with the wind and weak swell, a kite would have a much better time of it.
Rusty.

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