The Lowdown
Alright, Rusty here. Let’s take a look at what we’ve got on the table for Hennemans.
To be honest, it’s a tough stretch ahead. We’re looking at a pretty long gap before anything really gets going. The first couple of days are a write-off with poor surf and messy cross-onshore winds. There’s a bit of a window that looks more promising from Saturday the 5th through to Monday the 7th, but even then, we’re talking marginal conditions.
The standout in this whole 16-day window is going to be Sunday afternoon, the 6th of September. We’ve got a solid 6ft swell coming from the SSW, and the wind swings to a light cross-offshore from the NNW. That’s going to clean things right up. The combined wave energy is pumping at 1241 (moderate to strong), and it’s a long-period groundswell at 13 seconds, so the waves will have some real shape and power. This is a reef break that’s best with a W swell, and while the direction is SSW, it’s still offering the best wave quality of the whole outlook. That said, it’s an inconsistent spot, and crowds are sometimes an issue, so don’t expect to have it to yourself. The water is much warmer than normal for this time of year, sitting around 75°, with a big anomaly of 6° – that’s very unusual.
Monday the 7th is still worth a look, with similar 6ft SSW swell, but the wind is more cross-shore, so it won’t be as clean as the Sunday arvo window. Still, there’s good energy (1355).
After that, it starts to fade. From the 8th onward, the swell drops and the wind gets messy again. There’s a long stretch of poor to marginal surf through the second week, with only tiny knee-high waves and cross-onshore chop. The 17th and 18th see a very long-period swell (22 seconds) but it’s small and the wind is against it, so it’s nothing to get excited about for a reef break like this. That long period will make it tricky at Hennemans.
So, to sum it up: if you’ve got a free Sunday arvo on the 6th, that’s your best bet. A little inconsistent, but clean and punchy. Otherwise, you’re waiting a long time for anything worthwhile.
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.
