The Lowdown
Alright folks, Rusty here with the outlook for Rockpile. Let's be honest, it's been a bit of a flat spell, and the next week or so looks pretty slim. It’s a consistent reef break that’s best with a SW swell and with the wind coming from the NE, so the conditions we’ve got lined up aren't ideal.
Water temp is currently sitting at a very warm 72 °F, which is a solid 4 °F above the norm for this time of year. You won't need a thick wetsuit, that's for sure.
We start off with nothing worth paddling out for. The first few days are showing tiny, weak, and messy surf. It’s pretty much a write-off until we get to Wednesday the 19th, and even then, it’s only a *maybe*. Wednesday afternoon offers up a little 3 ft SW swell, but the wind is a light cross-on breeze, so it's not going to be clean. The energy is weak at a combined reading of 358. It's a marginal call at best.
The pattern of small, poor surf continues right through to the end of August. Most days are either onshore or cross-onshore with very little push. The swell height sits mostly between 2 ft and 2 ft, which is just enough for a tiny log if you’re desperate, but with the wind angles we have, it’s not worth getting excited about. The combined energy stays under 400 for most of this stretch, confirming how weak it is.
Now, there is a glimmer on the horizon. The last day of August and the first weekend of September show a bit more size. Saturday the 29th of August brings a 4 ft to 4 ft SW swell with a long period of 18 seconds. The energy jumps to a moderate 839 and 945, which is the most we've seen in the forecast. The wind is still a cross-on for the most part, which is a real shame. That long period swell would be lining up nicely from the SW, but it’s going to be a bit chopped up. Still, for a reef break, that longer period will bring some proper lines through, even if it's not glassy.
Sunday the 30th holds similar size at 4 ft, again with the SW direction but a shorter 16 seconds. The wind looks a touch lighter with a light breeze, so it might clean up a touch.
Honestly, if you’re desperate for a surf, the best bet looks like Saturday the 29th of August or Sunday the 30th of August. It won't be perfect, and the crowds are likely to be there since it’s a consistent spot that's been flat for days. The 4 ft to 4 ft SW swell is the standout size, but don't expect a clean, picture-perfect session. The wind just won't cooperate enough to make it a true gem.
Overall, it’s a long wait for something that’s only just okay. Keep an eye on the forecasts for that last weekend of August, but temper your expectations.
Stay salty, Rusty.

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