The Lowdown

Alright, grab a coffee and a towel, I’m gonna break down the next couple of weeks for us at Blacks Beach.

Right off the bat, we’ve got a challenging stretch. The water temperature is sitting at 73°, which is a solid 5° warmer than usual for this time of year – that’s one positive to hang onto. But the surf is going to test our patience. For the next several days, from Wednesday the 26th through to the end of August, it’s looking pretty flat and messy. The energy is weak (combined energy of all swells directed here around 332 to 211), with small, short-period swells coming from the SW and SSW. Winds are mostly cross-onshore or onshore, making for junky, poor surf conditions. You’ll be paddling for nothing.

We’re looking at a gap of about five days of basically no-go surf before things start to show a pulse.

The first real glimmer of hope arrives on Wednesday morning, September 2nd. We’ve got a SSW swell building to 4 ft with a 12-second period. The combined energy jumps to 657 (moderate). What’s really exciting is the wind: it’s glassy from the NW. That’s a dream scenario for Blacks. The forecast says "expect very good surf conditions." This is the standout of the whole outlook. The swell direction (SSW) is a little off the optimum (WNW) for Blacks, but with that glassy surface and a clean, lined-up groundswell, it’s going to be worth the wait. Crowds are "often" here, so expect a packed lineup if you’re keen.

The energy builds further into Wednesday afternoon and Thursday (September 3rd), with the swell hitting 5 ft to 6 ft (combined energy over 1000 – strong). However, the winds shift to onshore and cross-onshore, so the quality will be more marginal. That 6 ft is pushing into expert territory, too. The glassy window on Wednesday morning is definitely the sweet spot.

After that, the swell drops back into the 3 ft to 4 ft range through the first week of September, with onshore winds more often than not. It’s just marginal surf, not really a standout. The second week (September 6th onwards) sees the energy fade further, with poor conditions returning. The period finishes with a little spike in energy on September 9th (combined energy 516, moderate), but with cross-onshore winds limiting the quality.

Bottom line: The best bet in this 16-day window is clearly Wednesday morning, September 2nd. That glassy, 4 ft SSW groundswell at Blacks Beach is the real deal. Get out there early. The rest of the forecast is a waiting game.

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.
