The Lowdown
Alright, I’m Rusty, and I’ve been staring at this forecast for Hennemans. It’s a reef break that’s usually inconsistent and only works with a west swell. For the next 16 days, it’s mostly a tough run for intermediate surfers.
The pattern starts soft. From Tuesday 21 July, we’ve got small, long-period SW groundswells, but the wind is always in the way. Tuesday morning has a 1.1m SW swell with 629 combined energy, but the wind is cross-onshore, making it bumpy. Afternoon is a bit smaller at 0.9m (529 energy) and cross-shore. Not worth it.
Wednesday 22 July is a no-go: moderate cross-shore wind and chop, waves around 0.9m. Thursday 23 July stays cross-on with a 1.2m SSW swell (604 to 631 energy) and choppy conditions. Friday 24 July has onshore wind and a 1.0m swell (699 energy).
The best we get is Sunday 26 July. Morning brings a 1.0m SW swell with a very long period of 19 seconds and 940 energy. The wind is light onshore, so it’s not glassy, but that long period will wrap around the reef. The water temperature is about average for this time of year.
Monday 27 July morning has a 1.1m SW swell with 1014 energy and 18-second period, but again, onshore wind. The afternoon turns choppy. From there, it gets worse. Tuesday 28 July has a 1.2m to 1.3m swell (1106 to 1163 energy) but strong cross-onshore winds — blown out.
Then, on Friday 31 July, we see a bump: 2.0m to 2.2m SSW swell (1672 to 1979 energy). That’s moderate wave energy, but the wind is cross-onshore, making it bumpy. At that size, it’s too big for beginners and only for experienced surfers. The period is 14 to 15 seconds, decent.
After that, the swell drops fast. Saturday 1 August still has a 1.7m swell (807 energy) in the morning but onshore wind. By Sunday 2 August, it’s tiny — 0.6m. The final week from 3 August onward is a total blank: small waves, short period, poor conditions.
If I have to pick one moment, it’s Monday 27 July morning — the 1.1m swell with 18-second period and 1014 energy is the most promising, but you’ll still have light onshore wind. The reef needs clean west swell with offshore wind, and we’re not getting that. Crowds are possible here, but with this quality, it’ll be quiet.
Bottom line: a long, frustrating stretch for Hennemans with no real standout. Just a few small, long-period pulses that never get the right wind. It’s a waiting game.

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.
