The Lowdown
G’day, Rusty here. I’ve had a good look at what’s coming up for Chalky Mount over the next couple of weeks, and I’ll be straight with you – it’s a tough stretch. Really tough. The wind is almost constantly hammering this spot from the east, and that’s putting a cross-on chop on just about everything.
We start off on Tuesday the 11th of August with tiny, choppy junk. Swell is only 2 ft in the morning from the NNE at 9 seconds, so not much push (106 energy units). It’s all poor surf conditions right through the day. Wednesday the 12th sees the swell bump up to 5 ft from the ENE, period a short 7 seconds, but that cross-on wind is fresh at 19 mph, making it lumpy and messy.
Come Thursday the 13th of August, we’ve got a solid 8 ft from the ENE, period 8 seconds, but the wind is now a strong 25 mph cross-on. That’s a grinding mess – 750 energy units of pure chop. This is really more suited to a kite than a paddle board. That same pattern of cross-on east wind and poor surf holds all the way through to the end of the first week.
We finally get a little change on Sunday the 16th of August. The afternoon brings an 8 ft swell from the ENE with a period that jumps to 13 seconds – that’s proper groundswell energy, with 2576 energy units behind it. For a moment, the wind switches to ‘on’ at 12 mph, which is the closest we get to clean all window. But the forecast still calls it marginal, with questionable tide conditions. For an intermediate, this is the one to keep an eye on. If the tide plays ball, those long-period lines could offer something, but the crowd factor is ‘sometimes’ at this break, so you might have company.
The week after delivers more of the same story. Swell hangs around 3 ft to 7 ft, but it’s almost always from the ENE or E with short periods and a cross-on breeze that never really lets up. The best direction for Chalky Mount is NE, and that’s what we get a lot of, but the wind just trashes the surface. Water temp is sitting at 84° with an anomaly of just 0.7°, so pretty average for this time of year.
Honestly, the only real standout is that Sunday afternoon, 16th of August. The rest of the 16 days is a struggle. If you’re desperate, that late afternoon window on the 16th could surprise you, but otherwise, it’s a blank run. Keep an eye on the longer range, forecasts can shift.
Rusty.

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