The Lowdown

Alright, let's have a look at what Old Man Winter’s sending our way.

Well, mate, it’s gonna be a bit of a slow burn for the next week or so at Mullaway. We’re looking at a long stretch of nothing to get excited about through to the end of August, with only tiny, weak slop and ordinary conditions. The water temp is sitting at about 68°, which is pretty much average for this time of year, no surprises there.

For the first week, from Wednesday the 19th through to Monday the 31st of August, it’s pretty grim. There’s a pocket on Thursday morning the 20th where you might get a cheeky little 4ft swell from the ESE, period a short 7 seconds, and light cross-offshore NNW wind, but the overall energy is weak (196). The crowd factor at Mullaway can be an issue, and with surf that small, it’ll be a scrap for scraps. A couple of mornings, like Saturday the 22nd, see a glassy surface but only 2ft of swell. That’s honestly not worth the wax.

Then, around the 31st of August into early September, things start to get interesting. A proper pulse of long-period groundswell shows up. Monday the 31st sees the energy ramp up with a 5ft SSE swell at 11 seconds, but it’s cross-onshore. The energy is building, though, with readings of 549 (Monday morning) and 641 (Monday afternoon). But the real standout is Tuesday the 1st of September. We’ve got a 8ft SSE swell in the morning, period 14 seconds, building to a solid 12ft from the S in the afternoon, period 13 seconds. The combined energy is immense – 2851 in the morning and a whopping 6735 by the afternoon. This is serious groundswell, and for a point break like Mullaway, that long period can mean beautiful, lined-up waves, but it also means the sets will be widely spaced. This is expert territory for sure; beginners need to steer well clear of anything over 8ft.

Now, the wind on Tuesday isn’t perfect – it’s cross-onshore from the NE – so the quality will be a bit lumpy. But hold on. Wednesday the 2nd of September brings a real wildcard. The morning is a write-off with heavy rain and 16 mph cross-onshore winds, but the afternoon? Glassy conditions. Dead calm. A 7ft SSE swell at 12 seconds, with a very strong energy reading of 1381. That’s the one to lock in. Excellent surf for experienced surfers, clean and powerful.

If you can wait, the standout is definitely Wednesday afternoon, September 2nd, at Mullaway. Glassy conditions with a solid, long-period SSE swell. That’s the session you want to be in the water for. The earlier big days on the 1st will be for the chargers only, and the wind isn’t doing them any favours.

Rusty.

Information about the Mullaway Surf forecast

The above surf forecast table for Mullaway provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mullaway can be found by selecting the local surf guide option on the grey menu. Our Mullaway 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 (Mullaway) 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 Mullaway 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.
