Alright, let’s be honest with each other – this is a tough stretch of the forecast. I’ve been looking at the charts for Maslin Beach, and frankly, the surf is pretty much flat for the whole 16-day window. There’s no real swell to speak of, and what little shows up is messy, wind-affected, or just too small to bother with.
We’ve got a long gap of nothing happening. The first few days through to the 10th of July are either flat or ankle-biters with no energy, the kind of day you’d only paddle out if you just wanted to sit on your board and watch the clouds. The water temp is sitting right around 59°F, which is pretty average for this time of year, so no surprises there.
Then on the 11th of July, a little bump tries to show up – a 5ft swell from the NNW, but it’s short period (5 seconds) and the wind is howling from the NW at 25 mph, cross-onshore. That’s just messy. By the 12th of July, the swell size jumps to 8ft to 10ft from the WSW, but the period is still short (7-8 seconds) and the wind is onshore and strong. Wave energy is high (779-834), but it’s going to be a washing machine – more suited for kite surfing than a proper paddle session. The break is a beach and reef, so with that much onshore wind and a short-period swell, it’s going to be choppy and blown out.
After that, it drops off again. The 13th to 15th of July has some small, weak swell (2ft to 3ft) but the wind is either onshore or cross-onshore, and the period is short. The 16th of July finally sees a bit of offshore wind from the east (6 mph) in the morning, but the swell is only 0.7ft – not enough to get excited about. The rest of the window is flat or close to it, with no real push.
There is no standout. Nothing is worth highlighting. The consistent theme here is poor surf conditions across the board. Maslin Beach is a fairly exposed spot, so it’s not usually this quiet for this long, but this is one of those rare runs where the ocean just isn’t cooperating. The forecasts can change, but right now, I’d save the wax for another week.

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.
