The Lowdown
Alright folks, Rusty here. Let’s get into it.
Well, it’s a bit of a slow grind for the next week or so, to be honest. We’ve got small, inconsistent, and mostly cross-onshore wind at Rockpile (reef). The water is a toasty 73°, which is a full 6° warmer than usual for this time of year – that’s seriously unusual, so you might not need the thickest wetsuit, but don’t expect a proper winter swell to match.
The first real chance of anything decent doesn’t show up until Thursday, July 24. The morning sees a bump in combined energy to 1175 (moderate to strong), with a 4ft SSW swell riding a 13-second period. It’s still cross-onshore, but light enough to keep the chop manageable. The morning is your best bet, as the afternoon drops off.
The biggest standout, and the one I’d circle on the calendar, is Monday, July 27. The morning brings a 4ft SW swell with a lovely 18-second period – that’s proper groundswell, meaning real power and shape. The combined energy hits 1337 (strong), and the wind is light cross-onshore from the SSW, which is about as good as it gets for this spot. Expect clean, lined-up waves, but because it’s a reef and a long-period swell, it could be a bit more critical. This is the best session on offer.
After that, the swell hangs around through Tuesday, July 28, with a 4-4ft SW swell and 17-second period, but the wind picks up a touch. The morning of the 28th is still worth a look.
Then we hit a bit of a lull. The first few days of August are poor – small, weak, and messy. The next real glimmer comes on Tuesday, August 4. The afternoon sees a 5ft S swell with a 15-second period and combined energy of 1166 (moderate to strong). The wind is light cross-shore from the WNW, which is a clean setup. That’s a promising one, but it’s a long way out, so keep an eye on the charts.
So, to keep it simple: if you’ve got a free morning, make it Monday, July 27. The 28th is a solid backup. The 4th of August is a heads-up for the long-range.
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.
