The Lowdown
Alright, Rusty here again. Let's break down the same outlook but in the units the old-timers and travelers might be more used to.
Honestly, the next couple of weeks are looking pretty slim for a proper session. We start with a glimmer of hope, but then it's a long, drawn-out stretch of flatness.
We get things moving on Tuesday, July 28th, with a bit of a maybe at Blacks Beach. The water is sitting at a very unusual 75°, which is much warmer than you'd expect. The swell is from the SSW, coming in at about 4ft with a long 17-second period, giving us a moderate energy level of 963. That's a solid groundswell, but the wind is a light cross-onshore from the WSW at 6 mph, which will fuzz the surface up a touch. The forecast calls it marginal, and with crowds that can be *often* around here, it might be more trouble than it's worth. This one's for the advanced crew who know the spot.
After that, Wednesday the 29th still has some SSW swell around 4-4ft with that long period, but it's still not pumping. By Thursday the 30th, the bottom falls out. The swell drops to 3ft and the energy goes with it, and from there we enter a long, flat spell.
From Thursday, July 30th all the way through to Wednesday, August 12th, there's very little on offer. The swell heights stay mostly below 3ft, the energy is low to weak, and the wind, while light, is often onshore or cross-onshore, leaving the ocean a bit messy. There are a couple of moments around the 7th and 8th of August where a longer-period SSW groundswell shows up, but with heights of only 2ft to 3ft, it just doesn't have the power to make anything worthwhile at a beach break like Blacks.
The only tiny silver lining is at the very end. On Tuesday, August 11th, we see a small 1ft pulse from the SW with an 18-second period. The period is so long it almost feels like ocean memory. The energy is low, but if you're dedicated, you might find a clean little wave on the right tide, especially with the light offshore wind from the W. Then into Wednesday the 12th, it picks up a touch more size (2-3ft) and the energy climbs a bit, but the wind turns cross-onshore again, killing it.
So, the best bet in this whole outlook, and it's a sad state of affairs, is that first afternoon on the 28th of July at Blacks Beach. It's the only window with any real size, and if you can handle the crowds and the slightly bumpy surface, there might be a few long-period lines to be had. Everything else is a waiting game. For now, it's looking more like a kite-surfing setup than a paddle surfer's dream, given the light winds and small, weak waves.
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.
