The Lowdown
Alright, Rusty here with the read on the next couple weeks.
The first few days are a total bust. Nothing but tiny, weak swell and onshore wind through Thursday, 3 September. Don’t even bother waxing up.
Blacks Beach is the only spot that shows any life, and that starts Friday morning, 4 September. Swell is a little 3 ft from the SSW with a long 17-second period – that’s groundswell, so it’ll have some punch and decent shape. The wind is cross-on from the SW though, so expect some bumps. Wave energy is moderate (660). This one is for the advanced guys – exposed spot, not a learner’s wave.
The real winner is Saturday morning, 5 September. Cloudy, but the wind goes glassy out of the WSW at just 3 mph. You’ve got 3 ft of SSW swell with a 16-second period – clean, long-period groundswell, and that glassy wind will make the surface perfect. Wave energy is moderate (555). For a spot like this, that long period will wrap in and offer some real good lines. Since crowds are “sometimes”, you could have a few others out, but it won’t be a zoo. This is the absolute best of the whole 16-day stretch.
Saturday afternoon holds at 3 ft from the SSW, but the wind turns cross-on from the NW, so it won’t be as clean.
After that, it all dries up. From Sunday, 6 September through Wednesday, 16 September, the swell tanks and the wind stays messy or onshore. Sunday only has 2 ft of weak W swell with a short 10-second period – energy is just 46. Monday, 7 September goes dead flat – zero wave energy. There’s a bump on Tuesday, 8 September with 7 ft of short-period, 8-second SSW swell – that’s a lot of water but it’s going to be fat and sloppy, only for experts. Then it’s back to small, weak, and poor for over a week.
Water temp at Blacks Beach is 76°F – that’s about 8°F warmer than normal, so very unusual. You’ll be fine in a shorty or even just boardshorts.
So here’s the bottom line: the only day to make plans for is Saturday morning, 5 September. That’s the cleanest, most promising window. After the 7th, it’s a long stretch of nothing worth paddling for. But this spot can turn around quick, so stay hopeful.
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.
