The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – the next couple of weeks are a tough watch for Maslin Beach. There’s a big empty stretch at the start and nothing really gets going for a while. If you’re hanging for a wave, you’ll be waiting.
The forecast kicks off with a run of poor conditions from July 25 right through to August 5. The swell is tiny, wind is messy, and every report says “poor surf conditions.” You’re looking at waves mostly around 0.3 ft to 1 ft, with cross or cross-onshore winds messing up what little is there. The combined swell energy is barely a whisper, often just single-digit numbers (like 0, 1, or 5). It’s a long, flat gap with no recommendations at all – nothing worth paddling for.
Then on August 7, Friday morning, something changes. The swell jumps to 5 ft from the W, with a period of 6 seconds and a combined energy of 158 – that’s moderate energy. The wind is cross-shore from the N at 12 mph, which isn’t ideal but it’s not ruining it either. By Friday afternoon, it gets bigger: 7 ft from the WSW, period 7 seconds, and the energy rockets up to 471 – strong wave energy. That’s the standout of the whole 16 days. It’s sizeable, but at over 8 ft, this is expert territory only. The short period (under 8 seconds) means the waves will be a bit crumbly and less organised, not your classic groundswell. The wind stays cross-shore from the N, so it won’t be clean, but there’s power there. Maslin Beach is a beach and reef setup, so expect some shape but also chop.
Water temp on the morning of July 25 was 58°F with a -0.9°F anomaly, so about normal for this time of year. That’s the first break mentioned, so you know it.
The rest of the run after that big Friday is more of the same: messy wind and small swell. August 8 and 9 drop off fast. On Sunday the 9th, you get 4 ft from the WNW, period 5 seconds, energy 82 – weak – with a moderate cross-shore wind from the S at 12 mph. Nothing to write home about.
So here’s the truth: if you’re keen, August 7 (Friday) is your only real shot, and that’s a powerful, expert-only day with a lumpy cross-shore wind. For everyone else, it’s a long blank stretch where you’re better off checking back later. Forecasts can change, but right now, it’s quiet.
Rusty.

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