The Lowdown
Alright, surfers, let’s break it down. We’re talking about Hennemans, a reef break that’s not the most consistent spot around. It’s a fickle one. The water’s sitting at 70°, which is a touch warmer than usual for this time of year—a nice little bonus.
Right now, we’re in a bit of a lull. The start of the period is pretty quiet. Friday the 21st offers only small 2ft swell from the SW with a light cross-on breeze, and it’s looking marginal. The energy is weak (241). Saturday and Sunday are much the same story – small, messy, and not worth getting too excited about. We’ve got a few days of small, choppy conditions with that cross-onshore wind.
The first real hint of life comes around Tuesday the 25th afternoon. The swell picks up a bit to 4ft from the SSW, with a moderate wave energy (731). It’s still cross-on, but the wind is light, keeping it from being a total washout. It’s not a standout, but it’s a step in the right direction.
Now, Wednesday the 26th morning is the best of the first week, but it comes with a big caveat. We’ve got 5ft from the SSW, a period of 13 seconds, and some strong wave energy (1045). The wind is cross-on, though, so it will be a bit choppy. It’s a reef, so it handles the swell better than a beach break, but the wind is a drag. Also, that 5ft is getting into the size where beginners might struggle. It’s the best on offer, but it’s not perfect.
After that, we drift into a long stretch of marginal to poor surf. The days from the 27th of August through to the 3rd of September are mostly small, messy, and choppy. The swell hangs around the 3ft to 3ft mark, but the wind is never quite right. It’s a real frustration.
Hold on, though. The real standout, the one to circle on the calendar, is Thursday the 3rd of September in the afternoon. This is the one. The forecast shows a clean SW groundswell of 2ft, but it’s a long-period 18 seconds, which is a proper groundswell. The wind is a light cross-offshore from the NNW, and the wave energy is moderate (573). For a reef break like Hennemans, that long-period, clean south-west swell is pure gold. The conditions are expected to be very good. This is the pick of the entire 16-day window. It’s a bit of a wait, but it’s promising.
Friday the 4th and Saturday the 5th see the swell pick up again, but the wind is either onshore or cross-shore, so it’s not as clean as that Thursday session.
So, to wrap it up: the next couple of weeks are mostly a struggle with a few glimmers. The one real standout, and the best chance for a proper session, is that Thursday the 3rd of September afternoon. Keep your eyes on that day.

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.
