The Lowdown
Alright, this is Rusty. Let's have a look at what's on the table.
Honestly, mate, the outlook for Hennemans over the next couple of weeks is a bit of a tough one. It's a reef break, exposed to the west, but it's inconsistent, and the surf quality is just not dialing in for most of the run. We’ve got a long gap of marginal to poor conditions ahead. The water is sitting at a balmy 72°, which is much warmer than usual for this time of year – that’s the one nice thing.
The best window looks like it might shape up around Saturday and Sunday the 5th and 6th of September. Up until then, it's a lot of onshore and cross-onshore wind messing things up. Swell is mostly from the SW, but the wind is just never quite right.
Let’s break it down. Starting Monday the 24th of August, we’ve got a tiny 2 ft SW groundswell with a very long period of 17 seconds. The energy is weak (263), and we’ve got onshore wind. It’s not really doing anything for us. Tuesday through to the end of August is all small surf – 2 ft to 4 ft – with cross-onshore breezes and poor conditions. The combined energy fluctuates but it’s mostly weak to moderate (328–823), and the wave comment is consistently “marginal” or “poor”. There’s a morning on the 26th with 5 ft SSW swell at 12 seconds and moderate energy (823), but the wind is onshore and it’s marked as poor. Not the one.
We go into September the same way. Tuesday the 1st shows a little 4 ft SSW swell (491) with very light wind, but it’s still cross-onshore and the forecast is marginal. Then from the 2nd through the 4th it’s tiny and sloppy.
Now, here’s the standout. Saturday the 5th of September afternoon. The wind finally turns cross-offshore from the NNW at 12 mph. That’s a serious improvement. It’s going to be clean. Swell is 3 ft from the SW with a 16-second period – long period groundswell, which likes a reef setup like this. The combined energy is moderate (520). It’s not huge, but with that clean wind, it’ll be the best wave shape we’ve seen. Sunday morning the 5th has a bit more strength in the swell (4 ft, 16 seconds, 695 energy) with a cross-shore wind, but the afternoon on Saturday is the pick.
After that, the energy drops off again, and we’re back to cross-onshore breezes and marginal conditions for the rest of the forecast. The 8th of September has some 3 ft SSW swell with moderate energy, but the wind is on the nose again.
So, for a surfer, the call is simple. If you can wait, aim for the afternoon of Saturday the 5th of September. That’s your cleanest window with a nice, long-period groundswell wrapping in. It’s not a big day, but it’ll be the most fun you’ll have all forecast. Don’t bother with the rest unless you’re desperate for a paddle in warm water.
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.
Hennemans is 10 km (6 miles) from San Diego. If you plan a vacation in San Diego County, look for hotels and other accommodation in San Diego. San Diego has rooms for a wide range of budgets as well as car hire and transport links.
