The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Honestly, it's a tough stretch for Hennemans. This is a reef break that's exposed to the west, but the swell we're seeing is mostly from the southwest, and it's nowhere near the optimum westerly direction. The water temp is about average for this time of year. We're looking at a long gap with no proper surf on offer, and the conditions are pretty average for the most part.
Starting Tuesday, August 11, we've got a tiny, weak southwest swell, with waves around 2ft, but the wind is cross-onshore, making it choppy and messy. The combined energy is low (290). This theme continues right through the weekend. Every day we see poor surf conditions with cross-onshore winds, the swell stays small, and the energy is moderate at best, hitting 597 on the 15th. The swell period is long, around 14 to 18 seconds, suggesting a groundswell, but with the poor wind and the wrong direction, it's not doing much for us.
There's a slight glimmer on Thursday, August 13, in the morning. The wind goes light and straight onshore, and the swell is a tiny 2ft, which is called "marginal" at best. It's far from good.
The next week looks much the same. A lot of small, weak swells and cross-onshore winds. The only real standout, if you can call it that, is on Saturday, August 22, when the swell direction shifts to a westerly, which is much better for the break. The waves are predicted to be around 4ft, with a short period of 8 seconds, and the wind is cross-shore, meaning the surface might be a little cleaner. The combined energy is moderate (277-305). It's still not great, but it's the best the whole 16-day window has to offer. Keep in mind, Hennemans is an inconsistent spot, so this is the kind of window you get.
The rest of the forecast is more of the same with small, weak swells and poor winds. A few days in the last week of August show tiny 2ft swells.
So, the honest truth is, there's nothing here I'd be rushing to get wet for. It's a long, quiet run. The only one that even looks like it *might* be worth a look is that Saturday, August 22, with the westerly swell and cross-shore breeze. For the rest of it, you're better off waiting for a better forecast.
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.
