The Lowdown
Alright, Rusty here again. Let’s be real about Hennemans – this reef is looking flat, flat, flat. The whole 16-day window is a struggle, with just a couple of days that might be worth a paddle. The wind is blowing onshore or cross-onshore most of the time, which is no good for this spot.
We start on Monday, August 10th. The morning is a no-go: a tiny 2ft SW swell with a 13-second period, but that onshore wind at 9 mph from the WSW is a deal-breaker. The energy is weak (260). The afternoon is even smaller, dropping to 1ft, and the wind goes cross-onshore. Bummer.
Tuesday the 11th is the same story – small 1ft to 2ft SW swell, cross-onshore winds all day. The afternoon energy picks up a bit (422), but the waves are still chopped up.
Wednesday the 12th and Thursday the 13th are just more of the same: small waves, bad wind.
The first real chance comes on Saturday, August 15th. The swell bumps up to 3ft in the morning and 4ft in the afternoon, with a 16-second period from the SW. The energy is strong at 589-591. This is the best looking setup in the whole forecast. The wind is still cross-onshore, but the afternoon goes cross-shore, which is a big improvement. It’s still only marginal, but it’s the best we’ve got. Crowds are possible here, so don't expect it to be empty.
Sunday the 16th holds onto some size (3ft to 4ft), but the wind is back to being a problem. After that, it’s a long stretch of tiny swell (2ft to 3ft) and poor wind. The energy drops back into the weak to moderate range (133 to 461). There’s a little spike on the 25th with energy hitting 499, but the wind is cross-onshore again.
Look, for the full 16 days, there’s no real standout. If you’re absolutely itching, that Saturday the 15th is your best shot, but it’s not a day to get excited about. The reef is just not working right now.
Rusty.

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