The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer down at Hennemans over the next couple of weeks.
Straight up, I gotta be honest with you – this stretch is looking pretty quiet, and it’s going to be a bit of a struggle for most of the period. We’ve got a long, drawn-out run of small, weak swell and less-than-ideal wind angles. Don’t get your hopes up for anything firing. The water’s sitting at 71°, which is a touch warmer than usual for this time of year – not something you’d normally notice, but a nice little bonus if you’re out there.
The first real chance to paddle out, and I mean a slim chance, is on Friday the 21st of August. We’ve got a tiny 2ft swell from the SW with a period around 13 seconds. The combined energy is weak (246) and conditions are described as marginal. The wind is light and onshore to start, so the shape won't be great. It’s an inconsistent reef break here, so you’ll be sitting waiting for a long time between sets. It’s not a write-off, but honestly, it’s barely worth waxing the board for.
This quiet pattern drags on through the rest of August and into the first few days of September. The swell stays stubbornly small, mostly between 1ft and 2ft, with combined energy mostly in the low to mid hundreds – nothing with any real push. The wind flops around from the W and WNW, mostly cross-onshore, which keeps the surface a bit bumpy. There are maybe a couple of mornings where it’s light enough to get a slide on the absolute weakest of waves, but the forecast doesn’t wave any flags for excitement.
The one glimmer in this whole outlook, and I mean the one thing worth circling on your calendar, is the 29th of August. That Saturday morning we finally see a pulse of energy, with swell climbing to 3ft from the SW with a period of 17 seconds – that’s proper groundswell. The combined energy jumps to a solid moderate level (677). Now, this is a long period swell, and on a reef like Hennemans, that can mean some nice, lined-up waves, but it can also be a bit fickle and the sets will be spaced out. The wind is still a cross-onshore breeze out of the WNW, so it won't be glass, but it’s manageable and the waves will have some push. Afternoon drops back slightly but stays around 3ft. This is the standout, but it’s still only marginal overall; the forecast for the day is “marginal surf forecast or questionable tide conditions,” so don’t expect perfection. Even so, if you’re desperate for a surf, this is the best you’re going to get in this 16-day run. Just remember, crowds are possible here, so you might have some company if the word gets out.
Sunday the 30th holds similar size – 4ft from the SW with a 15-second period and moderate energy (580). The wind is more onshore, though, so the surface will get messier. Not the quality of the Saturday.
After that, the trend back down is quick. The first of September and beyond returns to tiny, weak swell with poor wind. Thursday the 3rd of September has a very small bump (2ft, SW), but it’s nothing to write home about and there’s rain showers that could make for a gloomy paddle.
Basically, it’s a long, quiet run with only one day that really stands out: Saturday the 29th of August at Hennemans. For the rest? You’re better off checking the forecasts again next week.

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.
