The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Blacks Beach.

Overall, the pattern is a bit of a slow burner. We’ve got a solid groundswell pushing in from the SSW, but the wind is going to be a constant chatterbox for most of the run. There’s a real standout window right at the start, but after that, it gets messy before fading into a long stretch of small, weak surf.

The first offer is the best of the lot. Friday morning, September 4th, we’ve got clean 3ft SSW swell with a period of 17 seconds—that’s proper long-period groundswell energy. The wind is light and offshore from the WSW, glassing things up perfectly. The water temperature is a notable 74°, which is much warmer than normal for this time of year, so it’s a real treat. Combined energy is a good moderate 668. This is the standout. The same afternoon holds steady with 4ft SSW swell, but the wind shifts to a light offshore WNW, still clean. Saturday morning and afternoon keep the 3ft to 4ft SSW swell coming with light offshore winds, staying clean.

Then things go south. Sunday, September 6th, the swell drops to nearly nothing (1ft-1ft) and the wind turns cross-onshore from the NNW, making it choppy and poor. That’s a dead day.

We get a spike in size on Monday, September 7th, with 7ft SSW swell. That’s pushing into expert-only territory, but the wind is cross-onshore from the WNW, so it’s going to be bumpy. Combined energy is very strong (1593). Not a clean day for paddle surfing, but for the skilled crew, there’s power. Tuesday and Wednesday see the swell drop back to 6ft to 2ft, but the cross-onshore wind keeps it choppy and marginal.

From Thursday, September 10th, all the way through Saturday, September 19th, the surf is small and weak. Swell heights hover between 1ft and 3ft, and combined energy mostly sits below 500. The wind is often light and offshore, but the swell is too weak to get excited about. The 15th to the 19th is a particularly flat stretch with poor surf conditions. There’s a small blip on the 17th with a very long 22-second period, but the swell is only 1ft, so it’s not going to do much at a beach break.

The real standout is that Friday morning session. Get it while it’s clean.

Rusty, signing off.

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.
