The Lowdown
Hey there, Rusty here. Let’s talk Hennemans. I’m not gonna sugarcoat it – the next couple of weeks look pretty grim. This reef break is inconsistent at the best of times, and the conditions are just not playing ball. Water temperature is sitting at 73°, which is nearly 5° warmer than usual for this time of year, so that’s a big anomaly – it feels like summer in the water, but the waves don’t match.
The first day that’s even worth mentioning is Saturday the 19th of September. There’s a 3ft south-west groundswell rolling in with a 18-second period – that long period is good for a reef setup like this – but the wind is cross-onshore from the west, so the surface is gonna have a little bump on it. The combined swell energy is building (519), so there’s some power, but it’s only marginal at best. This spot’s for intermediates, but honestly, it’s a tough call.
There’s a few days of nothing after that, and Sunday the 20th through Tuesday the 22nd stay marginal with similar 3ft to 3ft south-west groundswells. Wind stays cross-onshore, so the waves are never pristine. The energy stays moderate to strong (up to 603 on the 21st), but the quality is missing.
The one day that stands out – and I mean barely – is Tuesday morning the 29th of September. We’ve got a 2ft south-west swell with a 16-second period, and light winds from the west-northwest, keeping it glassy. It’s still only marginal, but for a break that rarely fires, this is your best shot in the whole 16 days. The energy is there (397), and the cross-shore breeze means less chop. Just watch for crowds – it can get a bit packed when the wave’s clean.
No big swell on the cards – nothing over 3ft – so beginners could try the smaller days, but the inconsistent nature and persistent cross-onshore winds make it a real mission. For most of this period, this looks better suited for kite surfing than paddle surfing. We’re in a dry spell, but forecasts can shift, so keep an eye on it.
Hang tight.

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.
