The Lowdown
Alright, let me take a look at what we've got for the next couple of weeks.
It’s gonna be a quiet stretch, folks. There’s nothing worth getting excited about in the immediate future. We’re looking at a long run of small, weak surf from now until around the middle of the month.
Things start off on Thursday morning, August 13th, with small 2ft SW groundswell. The wait between sets will be long with that 16 second period, but at a place like South Del Mar, a reef setup, it might actually wrap in okay. The wind is light onshore, though, so it’ll be bumpy. The combined energy is weak, just 330, and it’s being called marginal. Friday, the 14th, is a little better energy-wise, hitting 583 in the morning with a cleaner offshore breeze from the W. Swell is still small at 2ft from the SSW, but that 18 second period is very long. For a reef, that could mean some nice, shaping lines. Saturday morning, the 15th, has a similar story with 3ft SSW and 615 energy, but it’s still just a marginal call.
Honestly, none of this stuff is a standout. The wave quality stays poor or marginal right the way through. The water temp is looking about average for this time of year, nothing strange there.
We get a bit of a bump in energy around the 21st and 22nd of August, but we’re talking 2ft to 2ft surf with energy levels dropping. This is basically flat. Even the reliable 1 to 2-foot days are absent. There’s a small blip of 2ft, 19 second SW groundswell on Sunday the 23rd with energy at 425, but the onshore wind from the WNW won’t do us any favours. It’s still a “poor” call.
Looking further into the last week of August, it’s more of the same. 2ft to 2ft SW swells, light winds that are often onshore or cross-onshore, keeping things choppy. There is no day where the wind is truly glassy, and the swell never gets over 3ft. This is a real dry spell.
The only break on the list is South Del Mar. It’s a fairly consistent reef that’s good for beginners, but with the crowds often around here, even the small clean waves will be fought over. For now, the setup is just too small and weak for a proper paddle session. With this onshore wind and tiny bump, it honestly looks more interesting for a kite surfer than someone with a longboard.
There’s nothing on offer that’s worth rushing out for. Keep your gear waxed and hope the forecasts change, because this blank run is a tough one.

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.
