The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
To be straight with you, it’s looking like a pretty tough stretch. The forecast is a long line of days with poor surf conditions and scores of zero. We’re talking about a serious dry spell that kicks off now and runs all the way through until at least the morning of the 12th of August. There’s just nothing surfable on offer during that entire period.
Now, the main spot we’ve got on the radar is Blacks Beach. This is an exposed, consistent, advanced break that loves a WNW swell direction, and we’ve got some offshore wind in the early part of the forecast. But the problem is the wave energy and quality just aren’t there. On Thursday the 30th of July, the morning swell is only 3ft from the SSW, with a decent 15-second period, and the combined energy is moderate at 390. The wind is a light 6 mph offshore from the WNW, which would normally be a dream, but the water temp is a very unusual 75°F—that’s a massive 8°F warmer than what’s normal for this time of year. Still, the report says “poor surf conditions,” so it’s a no-go.
The only glimmer of anything even close to surfable shows up on the afternoon of the 12th of August. The swell bumps up to 3ft from the SSW, period at 17 seconds, and the combined energy jumps to 500 (moderate). The wind is a gentle 9 mph offshore from the W, which is clean. But even then, it’s labelled as “marginal surf forecast or questionable tide conditions,” with a score of just 1. That’s a long way off, and it’s not enough to get excited about.
After that, Thursday the 13th and Friday the 14th of August look similar—small SSW swell around 2ft to 3ft, long periods, and offshore winds, but still rated as poor. The energy is there in the water (moderate values in the 400s), but the quality isn’t.
There’s just no standout session in this 16-day window. The pattern is flat with a capital F. For an exposed spot like Blacks Beach, a blank run like this is normal for the area, so don’t hold your breath. Forecasts can change, but right now, you’d be better off waxing the kiteboard if you’re desperate for a fix, because the paddle surf looks like a total write-off.
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.
