The Lowdown
Alright crew, Rusty here. Let's get straight into it. Honestly, looking at the next couple of weeks at Hennemans, it's a tough stretch. This spot is inconsistent at the best of times, and we're in a bit of a flat spell with tricky winds. Don't expect much at all for the first week or so.
We're looking at a period starting now and going out 16 days. The first few days, from Sunday the 13th through to Tuesday the 15th of September, are a write-off with "poor surf conditions" all the way. Small, weak swells, mostly cross-onshore winds, just nothing to get excited about.
Things start to nudge into the "marginal" zone from Wednesday the 16th. You'll see tiny little 3 ft SW swells, but the energy is still low (around 410), and with a light onshore or cross-onshore breeze, it’ll be bumpy and not very clean. It's a reef setup so it can handle some direction, but the size is just too small for any real quality.
The best of a bad bunch looks like it might be Friday the 18th of September. We've got a 2 ft SW swell, but the period stretches out to 19 seconds. That's a very long period groundswell, and combined energy hits 508 (moderate). The wind goes cross-shore in the morning, which is the best we'll see. It's a reef break, so that long period should wrap in nicely, offering a bit more shape and those longer lulls between sets. But honestly, it's tiny. This is a standout purely because everything else is so poor.
After that, the rest of the run into the end of the month looks like more of the same: small 3 ft to 3 ft SW swells, with persistent cross-onshore winds. There's a couple of cross-shore mornings on the 24th and 25th of September, but the swell is still weak (energy in the 280-350 range) and the period is dropping off. It's hard to get excited.
The water temp is 73°F, which is a huge 5°F warmer than normal for this time of year – a real anomaly. Don't need a thick suit.
So to wrap it up, there's really only one session that pokes its head above the parapet: Friday morning the 18th. Even then, it's a small, marginal wave. This is a tricky spot at a tricky time of year. The reef can work, but we need a bit more size and some clean offshore wind to make it happen. Keep an eye on the charts, but don't hold your breath.
Stay patient,
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.
