The Lowdown
Alright, Rusty here. Let’s break down what’s happening at Hennemans.
First thing – the water’s warm. It’s 73°F right now, which is a solid 4°F warmer than normal for this time of year. You’re in for a comfortable session temperature-wise.
Now, the surf story is a tough one. For the next week and a half, conditions are mostly poor. We’ve got a run of messy, choppy days ahead. Swells from the southwest range from about 2ft to 4ft, but the wind is almost always cross-onshore or onshore, just killing any chance of clean waves. The combined wave energy sits in the moderate range, mostly between 200 and 400, but none of that matters when it’s blown out.
The first real glimmer shows up on the morning of Thursday, September 18th. The wind turns light cross-shore, and we get a 2ft southwest groundswell with a very long 19-second period. Energy jumps to 523. That long period means the waves will have some punch and shape, but at a reef like Hennemans, it could line up nicely. Still, it’s only marginal.
Your best bet is Sunday, September 20th. This is the standout. Light offshore wind from the southwest, clean conditions, and a 3ft southwest groundswell with an 18-second period. Energy hits 524, which is strong for this spot. Expect clean, peeling waves with some real push. Crowds are *sometimes* around, so don’t expect to have it all to yourself, but this is the session to aim for.
Monday the 21st is a decent backup – similar 3ft swell with a 17-second period, but the wind goes cross-onshore, so it won’t be as clean.
After that, it’s back to poor, choppy conditions for the rest of the forecast.
So, mark your calendar for Sunday the 20th. That’s your window for the cleanest, best shaped waves of the whole outlook. The rest is mostly a waiting game.
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.
