The Lowdown
Alright, grab a coffee and listen up. I’ve been over the charts for this stretch and, honestly, it’s a tough one. We’re looking at Hennemans, a reef setup that’s exposed to the west, and for the next two weeks, it’s just not playing ball. The water is a balmy 75°, which is a wild 7° warmer than usual for this time of year – that’s a real anomaly, feels more like a tropical bath than our usual winter water.
The pattern starts off pretty grim. The first real day we can even talk about is Saturday the 15th of August, but even then it’s marginal. The afternoon sees a small 4 ft swell from the southwest, with a period of 16 seconds. That’s a long-period groundswell, which has good energy, but it’s coming in with a cross-shore wind. The combined energy is moderate at 601, but with the wind chopping it up, it’s not a standout. The Saturday morning is even worse.
Then we hit a real dry spell. From Sunday the 16th right through to Monday the 24th of August, it’s a mess of poor surf conditions. The swell drops to under 3 ft, and the winds are mostly cross-onshore, making for choppy, bumpy waves. The combined energy drops into the 200s and 300s – weak to moderate. The reef is inconsistent at the best of times, and during this stretch, it’s barely worth a paddle. The whole of that week is a write-off.
The best of the bunch, and I mean the *only* real glimmer, comes right at the end of the outlook. On Tuesday the 25th of August, we see a pulse of new swell. The morning brings a 3 ft swell from the south, with a period of 16 seconds, and the afternoon bumps up to 4 ft from the same direction. The wind stays light and cross-onshore, which is about as good as we can hope for. The combined energy jumps to 816, which is a solid moderate energy. But it’s still a marginal call – the conditions are just “questionable.” It’s the best of a bad lot, but don’t get too excited. The long period means it’ll be a bit fat and tricky on the reef, but there’ll be some power in the sets.
After that, it fades back into the same old story for the rest of the month. So, if you’re desperate, mark Tuesday the 25th of August in your calendar. For everything else, maybe take a break.

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.
