The Lowdown
Right, let’s have a look at this coming stretch for Maslin Beach, a beach and reef setup that’s generally a beginner’s spot but on the inconsistent side. The water is sitting at 57°, which is about average for this time of year – nothing unusual there.
The 16-day window is a real struggle, I’m not going to sugarcoat it. There’s a long dry spell with no worthwhile surf for the first few days. The first real flicker of anything happens on Saturday the 8th, but it’s not good. You’ve got a 5ft swell from the north with a short, choppy period of 5 seconds, combined energy hitting 112 (moderate), but with a strong breeze from the NNW making it a messy cross-shore. That’s poor conditions, and the next day isn’t much better – Sunday the 9th has a 5ft swell from the WSW, period still a weak 5 seconds, energy at 117 (moderate), but a fresh onshore wind from the WSW is going to ruin it.
The best on offer, and I’m using that term loosely, looks like the morning of Tuesday the 11th. The swell jumps to 6ft out of the northwest, period still a short 6 seconds, but the combined energy is up to 208 (strong). The wind is a strong cross-shore from the north at 28 mph – it’s going to be messy and lumpy, but there’s at least some power in the water. Still, for a beginner spot, that 6ft is pushing the limit. For an expert, the biggest swell comes on Wednesday the 12th, with a 6ft swell from the west, period of 6 seconds, and energy at 251 (strong), but the wind is onshore and fresh. That’s a kite-surfing setup, not a paddling one.
After that, it drops off a cliff. From Thursday the 13th all the way through to the end of the window, it’s tiny – 1ft or less, mostly with weak energy under 100. The wind does go glassy or light cross-off at times, like on Sunday morning the 16th, but there’s nothing to surf. The long period swells (13-18 seconds) showing up on the 17th, 18th, and 19th are from the SW with almost no height – 0.3ft – so all that long-period energy is wasted. It’s a complete blank run for the second week.
Honestly, this is one of those frustrating outlooks where the forecasts are just not delivering. It’s a normal pattern for the area when it’s inconsistent, but it tends not to stay poor for long. Keep an eye on it.

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.
