The Lowdown
Righto, let’s have a look at what’s coming up for Blacks Beach. It’s a bit of a mixed bag to be honest, but there’s a window later on that’s got my attention.
Right now, the water’s sitting at 73°F, which is a whopping 6°F warmer than normal for this time of year – that’s really unusual, a proper tropical feel for a San Diego classic.
The next couple of weeks are looking pretty average for surf. There’s a long stretch of marginal to poor conditions from now until the end of July. We’ve got small swell hanging around 3ft to 4ft from the SSW and SW, with periods around 14 to 17 seconds – that’s a decent long-period groundswell, but the winds are mostly cross-on or onshore, keeping things messy. The wave energy is weak to moderate, so nothing to get excited about.
The real standout, and I mean the only one worth circling on the calendar, is the morning of Wednesday, July 29th. Swell comes up to 4ft from the SSW with a 16-second period, and the combined energy hits 1026 (moderate). The wind is a light cross-onshore from the SW, so it’ll be a bit bumpy but still surfable. The break is an exposed reef-point setup, so that long-period groundswell will wrap in nicely. It’s consistent, so you’ll get waves. The overnight winds look like they could be offshore, cleaning it up for the early session.
After that, Thursday the 30th and Friday the 31st drop off again with tiny, weak swell and poor conditions. Then on Saturday, August 1st, we see a pulse of 6ft from the SSW, but the period drops to 13 seconds and the wind is cross-on. That’s a bit too much size for a beach break with that wind, and the wave energy is moderate. It’s a kite surfer’s setup more than a paddle surfer’s.
For the experts out there, Blacks Beach is exposed and can handle the swell, but the crowds are often a problem, so expect company. The 4ft on the 29th is manageable for most, but it’s a reef, so know your limits. The wind is the key – if it stays light, it could be a fun session.

Information about the Blacks Beach Surf forecast
The above surf forecast table for Blacks Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Blacks Beach can be found by selecting the local surf guide option on the grey menu. Our Blacks Beach 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 (Blacks Beach) 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 Blacks Beach 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.
Blacks Beach is 13 km (8 miles) from the city of 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.
