The Lowdown
G’day, it’s Rusty here.
Look, I’ve been staring at the charts for Blacks Beach, and I’ve got to be straight with you: this 16-day stretch is a tough one. We’re looking at a solid run of days where the surf is just not cooperating. For the first few days, it’s pretty much flat and messy. There’s nothing worth paddling out for until Friday the 14th, and even then, it’s a marginal call at best.
The water is a toasty 76° at the start, which is a whopping 8° warmer than normal for this time of year. That’s very unusual, and honestly, it feels more like a bath than the Pacific. You’ll want the wettie for the stingrays, but that’s about it for the first few days.
The wind is mostly light, often offshore from the W or WNW, which is the right direction for Blacks. But the swell just isn’t there. We’re seeing small pulses of SSW and SW swell in the 2ft to 3ft range, with periods around 13 to 18 seconds. That longer period is a good sign, meaning there’s some energy in the water, but the height just isn’t enough to make Blacks fire. The combined energy is moderate, hitting 547 on Friday morning, but the wave comments keep saying “poor surf conditions” or “marginal.” It’s frustrating.
The weekend into next week picks up a touch. Saturday the 15th afternoon has the swell pushing up to 4ft with a 16-second period, and the combined energy is up to 706. But again, “marginal” is the word. The winds stay light, which is good, but the swell direction is a bit more SSW, which isn’t as ideal for Blacks as a more westerly angle. It’s a spot that prefers a solid WNW groundswell.
From the 17th onwards, it just fades away again. We’re back to 2ft to 3ft, and the periods start to drop back into the 14 to 16-second range. The energy is still moderate, but it’s not enough to get excited about. There’s a little bump in energy around the 26th, but the swell is still small.
So what’s the best on offer? Honestly, there are no true standouts here. If you’re desperate and you’ve got the patience, the Saturday afternoon session on the 15th looks like the closest thing to a wave. At 4ft of SSW swell with a 16-second period, and light offshore wind, it might just be rideable, especially for the more experienced crew. But don’t expect a classic Blacks day.
The rest of the window is a waiting game. We’ve got maybe a 10-day gap where nothing’s worth the effort. Conditions are pretty consistent, so it tends not to stay this poor for long, but this run is a real test. Keep your board in the car and your expectations low. The forecasts can change, but right now, it’s a quiet spell.
Rusty out.

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.
