The Lowdown
Alright folks, Rusty here. We’ve got a look at Hennemans, a reef setup that’s exposed to the west. It’s a tricky one, and honestly, for the next 16 days, it’s not delivering the kind of session we dream about. The swell is on the small side, and the wind is mostly cross-onshore, which keeps things a bit messy. There’s no standout period where everything clicks, so we’re looking at a long stretch of marginal conditions.
Starting off on Monday the 20th of July, we’ve got a small 3ft swell from the SW with a long 15-second period, but the cross-onshore breeze from the W at 15 km/h is making it choppy. The combined energy is moderate (546), but the quality is poor. That same pattern holds through Tuesday and Wednesday, with the swell bumping up to just over 3ft, but the wind stays cross-onshore, never really cleaning up. The water temp is about average for this time of year, so no surprises there.
Thursday the 23rd sees a slight bump in size to 5ft from the SSW, but again, the wind is cross-onshore, and the period drops to 14 seconds, making it less appealing. The combined energy is moderate (800). By Friday the 24th, we get a weird spike with a 24-second period on a very small 2ft swell, which is a classic groundswell. That long period can make it grovelly at a reef, but the energy is strong (1058). It’s still just a marginal call.
The rest of the run into early August is a slow fade. From Saturday the 25th through to the end of the month, the swell stays between 2ft and 5ft, with the wind mostly cross-onshore or onshore. The combined energy dips into the weak range (160) by the 3rd of August. The last few days of the forecast, from the 2nd to the 4th of August, are a complete write-off with poor surf conditions and very weak energy.
So, what’s the best of a bad bunch? The Friday the 24th of July morning has that weird long-period groundswell, but it’s tiny. The real standout, if you can call it that, is the Tuesday the 28th of July morning. We’ve got a 4ft swell from the SW with a 17-second period, and the combined energy is strong (1149). The wind is cross-onshore from the SSW at 15 km/h, which is not ideal, but it’s the biggest combination of size and energy in the whole window. It’s still not clean, but it’s the closest thing to a pulse we’ve got. Don’t expect perfection, but it might be the only time you see a wave with some push.
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.
