The Lowdown
Alright folks, it’s Rusty here, and I’ve got the lowdown on the next couple of weeks. Gotta be straight with you, it’s looking pretty quiet out there.
We’re starting off with a long stretch of nothing much to get excited about. For the first several days, from September 8th right through to September 17th, the surf is basically flat. We’re looking at tiny waves around 0.3ft to 0.7ft with weak energy and poor conditions. It’s a real bummer. There are a few morning windows with glassy or clean conditions on the 10th, 11th, and 16th, but with no wave height to speak of, there’s nothing to ride.
Then, after over a week of waiting, we finally see a pulse of energy around Friday afternoon, September 18th. The swell at Maslin Beach bumps up to 6ft from the WSW with a period of 6 seconds, and the combined energy jumps to 223 – that’s a moderate, short-period swell. Problem is, the wind is howling cross-shore at 12 mph, making it lumpy and choppy. That size (6ft) is getting too big for beginners, and the quality is pretty ordinary for a beach and reef setup. It’s the only real bump in the whole run, but it’s messy.
Later on, Monday morning, September 21st, offers a 4ft swell from the NNW with light cross-shore winds, but again, it’s a short period (5 seconds) and weak energy, so it won't have much push. The rest of the period is more of the same – tiny, weak, or blown out.
Honestly, for this stretch, the only day with some size is that Friday the 18th, but with the chop, it might be more interesting for the kite surfers than for us paddlers.
Stay patient. It won’t be like this forever.
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.
