The Lowdown

Alright, Rusty here. Let’s break down what’s coming for Blacks Beach over the next couple of weeks.

The overall picture is a mix of some decent groundswell pulses with clean windows, followed by a long run of poor-quality, messy surf. The first real action is on Wednesday, September 2nd.

Wednesday afternoon is a clean start: a 0.9m swell from the SSW at a 13-second period, with a light offshore WNW breeze at 9 mph. Wave energy is moderate at 403. The water’s sitting at 76°F, a massive 7°F warmer than normal for this time of year – very unusual. But the forecast calls it “poor surf conditions,” so that clean look might not translate into good shape or tide timing.

Thursday the 3rd and Friday the 4th see the swell building to 1.0m to 1.2m with periods stretching to 15-18 seconds. That longer period means more power and better shape, with wave energy reaching 636 to 799. But the wind goes cross-onshore, and the reports say marginal – small wind ripples and bumpy faces. Friday morning might be your best bet with that 1.0m SSW swell and a light cross-onshore breeze.

Saturday the 5th is the standout of the first week. Morning glassy conditions with barely a breath of wind, clean 1.0m to 1.1m SSW groundswell at 16 seconds, wave energy around 527 to 620. That’s a classic clean swell, and Blacks Beach exposed to the WNW will pick that up nicely. Crowds are often here, so expect company, but the quality will make up for it.

Sunday the 6th afternoon is another gem. The wind goes dead calm, glassy flat, with a 1.0m SSW swell at 15 seconds and wave energy of 470. That’s the best of the whole period – smooth, clean lines with zero chop. The morning has some light rain and cross-onshore, but wait for that afternoon window.

Monday the 7th and Tuesday the 8th bring bigger waves: 1.6m to 1.7m from the SSW at 13 seconds. Wave energy is strong at 982 to 1148. Offshore winds are blowing, but the reports stay marginal – could be a bit bumpy or tide-critical. Over 1.5m is expert territory, and with that period, it could be hollow and fast. Only fit for solid surfers.

From Wednesday the 9th, the size drops to 1.0m to 1.2m, and from the 10th through the 17th, it’s a long stretch of poor conditions. Cross-onshore wind, choppy, small swell dropping to 0.5m to 0.8m, and wave energy falling to 196. That’s an 8-day gap with nothing worth your time. The 17th of September afternoon shows a tiny 0.6m with a very long 21-second period, but with the wind onshore, it’s not going to be clean.

The real highlights are Saturday the 5th morning and Sunday the 6th afternoon for clean, glassy groundswell. Monday and Tuesday are for experts only. After that, it’s a kite-surfing kind of stretch with messy onshore wind and small surf.

Rusty.

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.
