The Lowdown

Alright folks, this is Rusty, and I’m looking at the charts for the next couple of weeks. Straight up, it’s a pretty quiet run for the most part with plenty of small, choppy days. There’s a glimmer of hope right at the tail end, but we’ve got to work through a lot of mediocre to poor conditions to get there.

We’re looking at Hennemans, a reef setup exposed to the west. The water temp is sitting right around average for the time of year, nothing wild there.

The first few days through the 18th and 19th of August are pretty bleak. Waves are tiny, around 2ft, coming from the SW. There’s a very long period of 16 seconds, which is proper groundswell, but with that size and a cross-onshore wind making it choppy, it’s just not doing anything. The combined energy is weak, values in the 300s.

Moving into the 20th and 21st, the wind actually swings onshore, becoming cleaner with a light breeze. The swell stays marginal, only 2ft and a shorter period around 13-14 seconds. The energy is still weak (around 237 to 297), and while the wind is glassy, it’s just too small to get excited about. It’s a "marginal surf forecast" situation – you might find a knee-high wave if you’re desperate, but nothing to write home about.

The weekend of the 22nd and 23rd is more of the same. The swell drops to 1ft on the Saturday morning, with a very long period of 18 seconds, but it’s cross-onshore and messy. The energy is still in the low to mid 200s. By Sunday, the wind picks up a bit, making it “fairly choppy.” There’s a gap here with no real recommendations.

The following week, starting Monday the 24th and running through to the 28th, is a rinse and repeat. Daily swells hanging around 2ft to 4ft, mostly from the SW or WSW, with periods varying from 8 seconds (short and weak) to 19 seconds (long but lifeless). The winds are generally cross or cross-onshore, keeping the surface bumpy. The combined energy stays in the 200s to low 400s. It’s a long, quiet stretch.

Now, hold on to your boards. The standout window shows up on the weekend of the 29th and 30th of August. The swell picks up to 3ft from the SW, with a solid period of 16-17 seconds. This is a proper groundswell. The combined energy finally jumps into a more moderate range, hitting 664 on the Saturday morning and 743 on the Saturday afternoon. The wind is onshore and light on the Saturday morning, making for clean conditions. The afternoon gets a cross-onshore breeze, but it’s still a gentle breeze, so it won’t ruin it. This is the best on offer over the whole period, but you’ve got to wait over a week for it. The Sunday the 30th looks okay too, but the wind gets a little more cross-onshore. It’s still a promising, cleaner window.

The very last days, the 31st of August and 1st of September, see the swell start to fade again, dropping back to 2ft to 3ft, with the wind turning more cross-onshore and choppy.

So, the long and short of it: This is a slow period for Hennemans. The reef setup is exposed, but it needs a proper push. The only real standout is the 29th and 30th of August when the energy gets a bit of a kick and the wind looks friendly. For the rest of the time, you’re probably better off doing something else. The forecast can always change, but right now, patience is the name of the game.

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.
