The Lowdown
G'day, Rusty here. Look, I'll be straight with you—this outlook for Hennemans is a bit of a slow burn. We're looking at a 16-day window that kicks off on August 20th, but for the first couple of weeks, it's mostly a waiting game. There's a long stretch of marginal to poor conditions, with just a few flickers of hope right at the end. The first real surf action doesn't show up until the final days of the forecast, so expect a lot of flat, choppy days before that.
For the first week, from the 20th through to the 29th, we're stuck with small, weak swell. The waves are under 3 ft, mostly from the SW to SSW, with a short period between 12 and 14 seconds. The wind is a constant cross-onshore, leaving the surface choppy and messy. The combined swell energy is weak, hanging around 242 to 751 (moderate), but it's just not enough to get excited about. The water temperature is sitting at 70°F, which is about 2°F warmer than the long-term average for this time of year, so it's a touch warmer than normal, but that's about the only positive.
Now, into the second week, things start to get a bit more interesting. On the 30th and 31st, we've got a little bump in size, but it's still marginal. The real standout, though, is the 3rd and 4th of September. On Thursday afternoon, the 3rd, we get a clean window with a NW wind, light cross-offshore, and a 2 ft swell from the SW with a very long period of 20 seconds. The combined energy hits 635 (moderate), and the wave comment is "expect very good surf conditions." This is a groundswell with a long period, so it'll be better suited for the reef setup at Hennemans, as it can break a bit too straight on a beach break. Then, on Friday morning, the 4th, we get glassy conditions with a 4 ft swell from the SSW, a 17-second period, and a combined energy of 984 (moderate). The forecast says "expect very good surf conditions" again. This is the best on offer—clean, offshore winds, and a decent size for a reef break. The afternoon of the 4th gets a bit cross-onshore, so the morning is the key.
Overall, the first two weeks are a bust, but the very end of the run has a couple of potential gems. Just keep in mind, being so far out, the details might shift, but for now, mark down September 4th morning as the one to watch.

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.
