The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the local stretch.
First up, we’re looking at Blacks Beach. It’s been a bit of a slow start, with pretty poor surf conditions kicking off the forecast period. The first recommendation doesn’t come until Friday morning, the 4th of September, and even then, it’s only marginal at best. The water temp is sitting about average for this time of year, so no surprises there.
The early part of the week is a write-off. The wind is onshore, and the swell is small and weak. We’re looking at a few days of nothing really worth paddling out for. The combined energy is low, around 241 (weak), and it’s just not shaping up.
Now, the standout is on Monday morning, the 7th of September. That’s your window. We’ve got a solid 8ft swell from the SSW, with a period of 14 seconds – that’s proper groundswell, good energy. The combined energy is reading 2650 (very strong). The wind is a light cross-offshore breeze from the NE, which will keep things clean. The description says “excellent surf conditions for experienced surfers”, and that’s no joke. At 8ft, this is for the advanced crew only. The swell direction (SSW) is a touch off the optimum (WNW), but it’s still going to fire. The crowd factor is “often”, so expect some company, but it’s worth it.
After that, the surf drops off quickly. The rest of the forecast window is a mix of marginal and poor conditions, with onshore winds and fading swell. The combined energy slips back into the hundreds and then low hundreds. There’s a brief flicker on Monday morning, the 14th of September, with a 1ft, 18-second period swell, but the energy is only 254 (weak), so it’s not much to get excited about. The long period (18 seconds) might make it a bit tricky at the beach break, but it’s too small to care.
So, to sum it up: the first few days are a total bust. The real action is on Monday morning, the 7th of September – that’s the one to circle. After that, it’s a slow fade into the second week. If you’re a beginner, steer clear of that 7th. For the rest of us, it’s a waiting game.
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.
