The Lowdown
Alright, this is Rusty. Let's have a look at what's on offer for Hennemans over this 16-day stretch.
Honestly mate, it's a tough run. We've got a small, inconsistent reef break here that's exposed to the west swell window, and for most of this period, the wind just isn't playing ball. There are days where the swell energy is moderate, but the direction and wind keep things messy. The water is sitting at a very warm 73°, which is much warmer than normal for this time of year.
Let's break it down from the start on Sunday the 16th. We see a swell around 3ft from the south-west with a 14-second period, but a 12 mph cross-shore wind from the WNW is going to chop it up, giving us poor surf conditions. That kind of wind at an exposed reef is a write-off.
Monday the 17th and Tuesday the 18th are much the same story. The swell drops a little and the wind, while lighter, stays cross or cross-onshore. There is a small window on Monday morning where conditions are only marginal, but with a 9 mph cross breeze, it's not worth paddling out for.
We go through a long, flat stretch here. From the 18th right through until the afternoon of the 25th of August, everything is rated as either poor or marginal. The wind is constantly cross-onshore or onshore, ruining any chance of a clean face. Even when the swell period stretches to a very long 19 seconds on the 23rd, it's paired with a 12 mph cross-onshore and rain showers – total mess. That long period would want a point break or reef to wrap around, not this one. For a beach and reef setup like this with these winds, you'd be better off looking at a kite.
Things finally settle down for the end of the month. From the 26th of August through the 28th, we get the closest we'll come to something worthwhile. The swell is still small, only 1.5ft to 2ft, but the wind drops to a light breeze at 6 mph or even less, giving us a glassy morning on the 27th. The energy is still moderate, but the surface will be clean. These are the only mornings I'd even look at the water, and you'd need a log.
For the last days, the 29th to the 31st of August, the wind shifts back onshore or cross-onshore, and the swell picks up to a consistent 3ft but it's blown out again. The energy is moderate, but it doesn't matter if the wind trashes it.
The standout, if you can call it that, is Thursday the 27th of August. It's a longboard day. The wind is light and cross-onshore, the swell is 2ft from the WSW, and it's one of the few mornings where you'll find a clean, small wave. Just don't expect much push.

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.
