The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the menu for South Del Mar.

It’s a pretty quiet stretch ahead, folks. We’re looking at a long patch of marginal to poor conditions, so don’t expect much action for a while. The first few days are a write-off, with small, weak swell and even the good wind direction can’t save it. There’s a gap from the start right through to the end of the first week where you’d be better off doing something else.

Now, the one real standout that’s worth circling on the calendar is Sunday the 6th of September. That afternoon, South Del Mar finally gets a pulse. We’re talking a solid 8ft swell from the south, with a period of 15 seconds – that’s a proper long-period groundswell full of energy. The combined energy hits 2858, which is very strong. The wind is a clean cross-offshore breeze out of the north at 16 mph, so the surface should be clean. This is a big swell, over 8ft, so this is strictly for the experienced crew. This reef break can handle that size, and with that south swell direction, it’s lining up nicely. Water temp is about average for the time of year, so nothing unusual there.

The Sunday morning is also sizable at 8ft from the south, but with a cross-shore wind, it’ll be a bit messier. Still, it’s an option for the brave.

After that, the swell drops off fast. Monday the 7th is still big but the wind swings around and makes it ugly. By Tuesday, we’re back to small, weak dribble. The rest of the second week is pretty flat or poor, with nothing really worth paddling out for. There’s a little bump of energy around the 10th and 11th, but it’s small and the wind isn’t kind. It’s a long, quiet end to the outlook.

So, to sum it up: if you’re an advanced surfer, Sunday the 6th afternoon is your best bet. For everyone else, it’s a waiting game.

Rusty.

Information about the South Del Mar Surf forecast

The above surf forecast table for South Del Mar provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at South Del Mar can be found by selecting the local surf guide option on the grey menu. Our South Del Mar 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 (South Del Mar) 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 South Del Mar 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.
