The Lowdown
Alright, Rusty here. Let's have a look at what’s cookin’.
First up, the water is sitting at a warm 72°, which is a touch warmer than normal for this time of year – feels good, right? But don’t let that fool you, because the surf situation at Hennemans is a bit of a slow burn. It’s an exposed reef break that likes a Westerly direction, and while we’ve got some serious energy in the water, the conditions are fighting us for most of the run.
We kick off on Sunday the 6th with a solid pulse of 6 ft SSW swell and a very strong combined energy (1569), but that’s coming with a 19 mph cross-off wind. It’s surfable but marginal, not the cleanest look. Monday the 7th drops off a touch in size to 5-6 ft, but the wind swings cross-shore and the energy drops to around 936, leaving a bit of a chop. Not great.
Then we hit a quiet phase. From Tuesday the 8th, the swell drops to around 3 ft, though Tuesday afternoon cleans up with a light cross-off breeze. Glassy conditions arrive on Wednesday the 9th, with tiny 2-2 ft waves but a very long 16-second period groundswell and glassy wind – that’s clean but small. The combined energy is moderate around 399-416.
From the 10th through the 21st, it’s mostly a write-off. The swell sticks small, mostly under 3 ft, with onshore or cross-onshore winds messing it up. Periods drop to 8-10 seconds from the 13th to the 15th, which is short-period, junky stuff. A few afternoons in the second week show a bit more energy (500 to 687 combined energy), but the wind is always cross-on or onshore, and the swell is weak at 2-4 ft. The 18th and 19th see a long-period 18-19 second swell, but again, the cross-onshore wind kills the quality. This spot is inconsistent at the best of times, and it rarely looks good in this window.
The only real standout is the brief glassy window on Wednesday the 9th. It’s small, but if you’ve got a log, the conditions will be perfect for a few clean, small waves. That’s the one to eye. Everything else is either too windy, too weak, or too choppy to get excited about. Crowds are possible here, so if you hit that Wednesday window, you might have some company.
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.
