The Lowdown
Alright, let's get into it.
Alright, let’s talk about Mullaway, and I gotta be straight with you – the next 16 days are looking like a real battle for a decent wave. This is not a period to set your watch by. There’s a big gap at the front end. The first couple of days are a total write-off with tiny, weak, and messy surf. We’re looking at a long dry spell.
From the 16th, things start to get interesting, but it's more of a wild animal than a tame one. We get a big pulse of swell on Wednesday the 16th, with the combined energy building to (647) by the morning and then absolutely roaring to (1582) in the afternoon, with the swell size climbing from 8ft to 10ft out of the SSE. This is solid, powerful groundswell with a period around 9 seconds, but the wind is a strong cross-shore, making it lumpy and messy. Honestly, with that much wind and muscle, this is going to be messy and tough.
Thursday the 17th still has some serious size, holding around 10ft in the morning from the S and still a lot of energy (3005), settling to 8ft in the afternoon (2320). The period stretches to a proper 10 seconds, suggesting some good lines, but the cross-shore wind is still there with a moderate breeze. The quality is described as ‘marginal’, so it’s not the clean, groomed wave you’d want. For surfers, this is big, tricky, and blown-out. If you’re a kite surfer, the setup from Wednesday through Thursday looks far more appealing.
Now, looking at the standout. If you want to paddle surf, you have to be patient and wait until the morning of Saturday the 19th. That is the one window where everything aligns, even if the swell is small. The combined energy is (184), with a modest 3ft SSE swell, period of 9 seconds. But the wind goes glassy – that’s a major positive. It will be clean. It won’t be big, it’s a mellow 3ft, but for a point break like Mullaway that is a known entity, that rare glassy morning will be the best of the month so far. It’s not big enough for advanced surfers to get excited, but for a longboard or a funboard, that will be a beautiful session.
After that, the outlook really falls apart. We get a mix of tiny swells with onshore winds, and some very long period (15-17 seconds) energy from the SSE on the 23rd and 24th, but the swell is tiny (2ft to 3ft) and the wind is onshore. That kind of long-period energy needs a clean pocket to work, and with an onshore breeze, it’s just going to be lumpy and weak.
So, the honest take: The 16th through the 18th is big, dangerous, and messy – a kiteboarder’s dream. If you must paddle surf, circle Saturday the 19th. The glassy morning will be a real joy, even if the swell is small. The water temp is about average for the time of year, sitting just above 68°.

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