The Lowdown
Alright folks, Rusty here. Let's talk about what's on the table for Hennemans. This is a reef setup, exposed to the swell, and it's an inconsistent spot so we need the conditions to line up just right. The water is running much warmer than normal for this time of year at 75°.
Right now, we are looking at a long stretch of pretty average to poor conditions. From Wednesday the 12th right through to the end of the week, we've got a mix of weak, long-period SW swell pushing in around 2ft to 3ft, but the wind is mostly cross-onshore or onshore, which is just going to chop things up. The combined wave energy is sitting in the moderate range, but the quality just isn't there. It's not worth paddling out for.
We hit a bit of a shift on Saturday the 15th and Sunday the 16th. The swell bumps up just a touch to 3ft to 4ft from the SW, and the energy climbs a bit. The wind is still cross-onshore, but the reports call it "marginal" rather than outright poor. This is the best of a pretty flat week, but honestly, it's still not going to be clean. The period is around 15-16 seconds, which is a proper groundswell, so you'll get long lulls between sets, but that cross-breeze is going to mess with the face.
Then we get a dead patch. From Monday the 17th through to Tuesday the 25th, we are looking at a lot of days with small, weak swell (2ft to 3ft) and persistent cross-onshore or onshore winds. The energy drops off a cliff. It's a real blank run. For a spot that's already inconsistent, this is pretty normal – we just have to wait it out.
The only glimmer of something better comes right at the end of the forecast, on Wednesday the 26th of August. The swell picks up to 3ft from the SW with a 16-second period, and the energy climbs back up. More importantly, the wind swings light and variable, which could give us some cleaner lines. It's still "marginal" but it's the best call in this whole outlook. The following day, Thursday the 27th, has similar swell size (4ft) but the wind swings stronger and more cross-onshore, so the 26th is the one to circle on the calendar.
So, if you're looking for a session, the 26th of August is the standout, but it's a long way off and the quality is still uncertain. The rest of this run is a real struggle for paddle surfing.
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.
