The Lowdown
Alright folks, Rusty here. Let's get into it.
First up, we're looking at a bit of a mixed bag. We've got some pulses of energy coming through, but the wind isn't always playing ball. The water here is running at a balmy 75°, which is a whopping 8° warmer than usual for this time of year. That's seriously unusual, so you might not even need a spring suit.
The first real chance to get wet kicks off on Wednesday, the 22nd of July, but honestly, it's a tough start. The swell is a modest 3 ft from the SSW, with a combined wave energy of 434 (moderate), but that cross-on wind from the WNW at 9 mph is messing it up. The surf report says "poor surf conditions," and I’d have to agree. It’s going to be pretty choppy and messy. You'd be better off waiting.
Friday the 24th of July shows a glimmer of hope. We’ve got a clean 2 ft from the SW and the combined energy jumps to 669 (moderate), but the wind is still a cross-on affair. It’s only a *marginal* call from the forecast, so temper expectations, but the setup is a little better than Wednesday.
Now, here’s where it gets interesting. The standout window looks to be Monday the 27th and Tuesday the 28th of July. The swell builds to 4 ft - 5 ft from the SSW, and the combined wave energy rockets up into the four-digit zone, hitting 1117 and then 1234 (strong). For Blacks Beach, that's a nice size. The catch is that the wind is still a gentle cross-onshore from the WSW at 9 mph. It’s not perfect, but it’s the best wave energy of the entire period. It'll be a bit lumpy, but there's plenty of push.
After that, the energy fades. By Wednesday the 29th we're back to 4 ft, and the combined energy drops to 764. The winds stay similar. Thursday the 30th of July is the last day I'd really bother with, with the swell holding at 4 ft but the energy dropping to 579. It’s a slow fade into the weekend.
From Saturday the 1st of August onwards, things go flat and poor. The swell drops to 2 ft - 3 ft, and the combined energy is down in the 100s (weak). The forecast is all "poor surf conditions" from there right through to Thursday the 6th of August. It's a solid, blank run for about a week. Nothing to see.
So, bottom line: The best surf in this 16-day window is Monday the 27th and Tuesday the 28th of July when the energy is strongest. It won't be glassy, but there's enough power to find a few corners if you pick your peak.
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.
