The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the table for the next couple of weeks. We’ve got one spot on the radar, and it’s a classic, but it’s going to be a game of patience.
Right off the bat, we’re looking at a bit of a slow start. The surf is small and messy, with conditions tagged as marginal or poor. The first real glimmer of hope doesn’t show up until the weekend of August 30th and 31st, but the swell is small, around 2ft to 4ft, and the wind is a persistent cross-on or onshore breeze. It’s not totally flat, but it’s not worth paddling out for.
The standout window is actually a fair way out. Let’s talk about Blacks Beach. The real juice shows up on the morning of Tuesday, September 8th. We’re looking at a solid 7ft of swell from the SSW, with a period of 13 seconds. That’s a proper groundswell with good energy – the combined energy reading is a strong 1413. The wind is a gentle cross-onshore, which will keep the surface workable, but it’s not glassy. Because the swell is over 5ft, this is getting into the territory where it’s a bit much for the beginners, and by the afternoon, it nudges up to 7ft, pushing it into the zone for experienced surfers only. The direction is SSW, which is a solid angle for this exposed break.
The water temperature at Blacks Beach is sitting at 76°F, which is a whopping 8°F warmer than normal for this time of year. That’s very unusual, so you’ll be surfing in a warm bath.
Earlier in the week around September 4th and 5th, there’s a small pulse of 3ft to 4ft SSW swell with a long period of 16-17 seconds, and light offshore winds from the west. That’s clean, but small. The long period will make for some nice lines at a point break, but at a beach break like Blacks, it might stand up a bit too straight. The energy is moderate (around 848).
The big pulse on September 8th is the one to watch, but it’s over a week away, so keep an eye on the forecasts. After that, things drop off again quickly, with the swell fading and the wind turning dicey.
So, to sum it up: the waiting game is on. The only real standout is the Tuesday, September 8th window at Blacks Beach. It’s for the experienced crew, it’s a bit raw with the cross-onshore wind, but the size and energy will be there. The rest of the 16 days is mostly small and marginal.
Stay patient, and don’t get too excited about the long-range stuff until it’s closer.
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.
