The Lowdown

Alright, Rusty here, let’s talk about what’s on the table for The Gallows.

The Gallows is a reef break that really only suits advanced surfers, and for the next two weeks it’s one of those stretches where the swell is just too much of a good thing. We’re looking at a solid run of big, powerful WSW groundswells rolling in with very long periods of 14 to 16 seconds. The wave energy is pumping hard, hitting that strong to very strong range (wave energy values in the thousands), so there’s no shortage of juice. But the problem is, for an exposed reef like this, when the swell is over 8 feet, it’s expert territory, and a lot of this period has swells around 10 feet to 15 feet. The water is sitting at 67°, which is a touch warmer than normal for August.

Let’s run through the dates. Things start off on Tuesday morning, August 18th with a massive 15-foot swell out of the WSW, period 16 seconds, and the wave energy is through the roof. There’s a brief window of favourable wind and tide, but the forecast is clear: the swell is predicted to be too big for this break. The wind is a gentle WNW breeze, which would have been nice in smaller surf, but not here. That afternoon, it gets worse with a NW cross-onshore breeze at 15 mph and poor conditions.

The whole of Wednesday the 19th and Thursday the 20th stay in that same boat – 13-foot to 15-foot swell, still with that massive 16-second period, and cross-onshore winds from the SW at 12-15 mph. A few slots are flagged as having favourable wind and tide again, but still the swell is just too big, making it unsurfable. The energy readings are insane.

Friday morning, August 21st, looks tempting for a split second. We’ve got a glassy calm morning with 12-foot swell... but again, the system says it’s too big for this break. That is a real shame, because glassy conditions on an 12-foot groundswell would be a dream at a different spot. The afternoon goes cross-onshore.

Saturday the 22nd sees the swell drop slightly to 10 feet in the morning with a light cross-shore breeze, and it’s still flagged as too big. After lunch, the wind cranks up to 18 mph from the SSW, creating poor, lumpy conditions.

From Sunday the 23rd onwards, we enter a long stretch of messy, cross-onshore winds that really spoil any chance. The swell hangs around 8 feet to 10 feet, but the wind is onshore or cross-onshore from the SW and SSW, and the wave comments turn to “poor surf conditions” and “marginal” for days on end. There’s no standout window here.

We get a bit of a lull around Thursday the 27th and Friday the 28th with the swell dropping to 4 feet to 8 feet, but the wind is howling at 25 mph from the south, making the ocean a cross-shore, lumpy mess. Not worth it.

The end of the month and into September isn’t much kinder. Saturday the 29th and Sunday the 30th have some 8-foot WSW swell with lighter winds, but it’s still cross-onshore and only rated marginal. Then on Sunday afternoon and Monday, August 31st, we see another pulse of 10-foot swell and even a brief window of favourable conditions, but once again, it’s flagged as too big for The Gallows.

Best on offer: If you *have* to paddle out, the morning of Friday, August 21st is the best the period gets. Glassy conditions, an 12-foot WSW groundswell with a 15-second period, and massive wave energy. But honestly, at this size on this reef, and the fact it’s called out as too big, it’s for experts only. The very end of the run, Monday afternoon, August 31st, has a glimmer with 8-foot swell and calm offshore winds from the WSW, and it gets a marginal score. That might be the most accessible wave of the whole two weeks, though it’s still powerful. Crowds are listed as “sometimes,” so expect some company at this reliable spot if the conditions finally line up.

Bottom line: The Gallows has the swell, it has the energy, but it’s mostly too big and too windy to be any kind of fun. Keep an eye on that 31st August afternoon window.

Information about the The Gallows Surf forecast

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

The Gallows is 79 km (49 miles) from the city of Bunbury. If you plan a holiday in Margaret River, look for hotels and other accommodation in Bunbury. Bunbury has rooms for a wide range of budgets as well as car hire and transport links.
