The Lowdown

Alright, Rusty here, checking in with the outlook for your local line-up.

Overall, the next two weeks are a bit of a mixed bag, but we do have some windows of opportunity. The water's sitting at a very warm 73°, which is much warmer than usual for this time of year, so you can leave the thick rubber at home.

Right now, the surf is pretty poor. We’ve got small, weak waves in the 2ft range from the SW with a long period of 18 seconds, but it’s cross-onshore and messy. The combined energy is only moderate at 381. It’s not worth the paddle.

Things start to look a little more interesting around Friday the 18th. The swell picks up to 2ft to 3ft from the SW, but the key here is that the wind goes straight offshore, blowing from the W to WNW. The wave energy builds through the weekend, hitting a solid 687 by Sunday morning, though it's still a bit onshore. It’s a marginal call, but if you time it right with the tide, there could be a clean little wave.

The real standout in this window, and the one to circle on your calendar, is Blacks Beach. It’s exposed to the open ocean, and from Saturday the 19th through Monday the 21st, we see the best conditions. The swell holds steady around 3ft to 4ft from the SW, with a long period of 17-18 seconds. That long-period energy will wrap in nicely. The wind is light and offshore, especially on the 19th and 20th, making for absolutely glassy conditions. It won’t be huge, but for a consistent, advanced break like Blacks, that’s a perfect size for some long, clean lines. Expect a crowd, because everyone will be on it.

The week starting Monday the 22nd drops off again. The swell stays small, generally 2ft to 3ft, and while the wind is mostly offshore, it’s just not got enough energy. The wave energy falls back to moderate levels, around 287 to 503. There are a few marginal sessions, like the morning of Tuesday the 22nd and Sunday the 27th, with some light cross-onshore wind, but nothing you’d rush for. It’s a bit of a flat spell.

Late in the period, Tuesday the 29th offers another marginal call with 2ft SW swell and light cross-on wind, but again, it’s small. The wave energy is only 321.

So, to sum it up: the first few days are a write-off. The best bet is the weekend of the 19th to the 21st at Blacks Beach, with clean, offshore conditions and fun, long-period swell. The following week is quiet, with only a few small, dicey windows.

Keep your eyes on that weekend, that’s the real chance for some magic.

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.
