The Lowdown
Alright, let’s keep it real. Maslin Beach is looking flat as a pancake for the next 16 days. Not much to work with at all.
Starting Saturday the 18th of July, we’ve got a tiny 0.3ft SW swell going glassy in the afternoon with a 5 km/h west wind. The combined wave energy is a weak 8 (combined energy of all swells directed here). Clean, but hardly surfable. Water temp is about normal for this time of year.
Sunday the 19th through to Saturday the 25th is more of the same – tiny waves mostly under 0.7ft, cross-shore winds, energy under 20. It’s a flat spell.
Sunday the 26th of July sees a bump to 3ft with a 4-second period, but a fresh 30 km/h north wind makes it lumpy. Energy hits 36 (weak). Not good. Monday the 27th drops back to 1ft, still messy.
The only real chance comes on Wednesday the 29th of July. We get a 6ft NW swell, but the wind is cross-on from the NW at 25 km/h. Combined energy is 169 (moderate). At 6ft, it’s more for experienced surfers. The wind will chop it up. Then on Thursday the 30th of July, a 6ft SW swell with a 6-second period and lighter north wind in the morning (10 km/h, cross). Combined energy is 210 (moderate). That Thursday morning is your best bet – still not perfect, but the cleanest window in a long, dry stretch.
After that, it fades to tiny, messy stuff through to the 2nd of August. If you’ve got to paddle out, aim for Thursday the 30th of July morning. Otherwise, save your energy.

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.
