The Lowdown
Alright folks, Rusty here. Let's take a look at what's coming down the pipe for the next couple of weeks.
Straight up, it's a tough outlook. The forecast shows a gap in quality surf for the first few days. We've got a brief window of marginal surf starting Tuesday, July 28th, but it's nothing to write home about. The real story is a long, quiet spell that follows, with a whole lot of nothing recommended for the best part of a week and a half.
The only named break in the mix is Blacks Beach. It's a consistent, exposed spot that's known to handle a good swell, but the conditions just aren't cooperating. The first chance of a wave comes on Tuesday, July 28th. We're looking at a 5ft, long-period SSW groundswell (17 seconds) pushing through. The combined energy is a moderate 1214, but it's all blown out by a 9 mph cross-onshore wind. The sets will be there, but it'll be a choppy, bumpy affair. Definitely not the clean Blacks we dream of.
From Wednesday the 29th, it gets smaller and wind stays messy. By Thursday the 30th it's down to 3ft with a better wind direction, but the energy drops off a cliff and the surf quality is still poor. Then from Friday, July 31st, things go flat with a tiny 2ft, short-period windswell for a few days. The combined energy reading plummets to 26, which is as weak as it gets.
We see a tiny blip of energy on Saturday, August 1st, with a 4ft SSW swell, but again the wind is onshore-ish and the scores are still poor. After that, we're stuck in a rut. From Sunday, August 2nd, all the way through to Wednesday, August 12th, the forecast is nothing but poor surf conditions. Swell heights barely reach 3ft, and the combined energy never gets into the moderate range. The winds are a mix of light cross-onshore and onshore, which doesn't do anyone any favors.
The best you can say is the water temp is about average for the time of year, but that's little comfort when there's no real surf.
So, to be honest, there's no standout session here. The only period that even offers a glimpse is the Tuesday, July 28th morning, but with the wind and the marginal rating, it's a real gamble. For the rest of the 16 days, it's a waiting game. The forecast is clear for weeks ahead, so it's a good time to tune up the gear or find a flat-water hobby. Hang in there.
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.
