The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
To be honest, it's a pretty grim stretch ahead. The whole 16-day window is a real struggle for any decent surf. We're looking at a long, dry gap with nothing worthwhile on offer. The swell is tiny, the wind is often messy, and it's just not doing anything for us.
Maslin Beach, a beach and reef setup exposed to the SW, is the only spot in the mix, and it's an inconsistent one at the best of times. The water temp is about average for this time of year.
Starting off, Tuesday the 21st and Wednesday the 22nd are a write-off. We're talking about ankle-snappers at best, with a weak combined energy and messy onshore winds. Thursday the 23rd and Friday the 24th bring a bit more wind, but the swell is still tiny and poor quality. The combined energy barely gets into the low 30s, which is just weak.
We finally see a slight flicker on Sunday the 26th. The afternoon looks glassy, with a light west wind. The swell is a pathetic 3 ft, but at least it's clean. The energy is still weak. Monday the 27th is the best of a bad bunch. We've got a 4 ft swell from the WNW, with a period of 5 seconds, so it's a short-period windswell. The wind is light and variable, with the afternoon going glassy. The combined energy is still weak. It's not going to be great, but it'll be the cleanest we see all period. Don't expect much.
The rest of the run is a complete washout. From Tuesday the 28th right through to Wednesday the 5th of August, the swell drops to practically nothing, the wind howls from the north and west, and there's even rain in the forecast. The combined energy plummets into single digits. For a spot that's already inconsistent, this is a normal blank run.
Given the persistent poor quality, small swell, and often strong wind at a beach and reef setup, this whole period looks more interesting for kite surfing than paddle surfing. I wouldn't bother wasting the wax. When the swell is this small and the wind is this strong, it's a kite show.
Stay patient,
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.
