The Lowdown

Alright, Rusty here again, but I'll switch it up for you.

Let's be straight. The next couple of weeks are a grind. The swell is showing up, with some good energy pulses, but the wind is the enemy. Almost all of this run is cross-onshore or onshore at Blacks Beach, which is the only spot we're looking at. It’s a real bummer because the water is a warm 73°F, which is a wild 5°F warmer than normal for this time of year – feels like a tropical fluke.

Let's talk dates. Starting Tuesday the 15th, we’ve got a tiny 2ft south-west swell, but with a 9 mph cross-onshore breeze, it’s just choppy and sloppy. That pattern hangs around for days. The combined swell energy is moderate, but it doesn't matter when the wind is mushing out every wave.

There’s a small window on Saturday morning, the 19th. The swell picks up to 3ft from the SW, and the wind turns straight onshore, but the energy is starting to build. It’s still marginal – a “maybe if you’re really keen” kind of session.

The best of a tough run is Sunday the 20th. The morning shows a bump in energy with the swell at 3ft from the SW. It’s still cross-onshore, but it's the lightest wind we'll see for a while. It’s the only time the odds roll in your favour, but it’s still just marginal.

By Monday the 21st, the swell holds a little bigger at 4ft from the SW, and the energy is getting solid. But again, that cross-onshore wind at 9 mph just tears it up. It would be a lot of paddling for not much fun.

After that, it’s a slow fade. The swell drops under 3ft and stays small, and the wind never really gets right. There’s a little more wind on the 26th, but the direction is wrong.

Look, Blacks Beach is a heavy, exposed wave that needs clean glass to be good. This forecast is a long stretch of onshore junk. If you're dying to get wet, Sunday the 20th morning is your best shot – it's the least messy. The second week looks even flatter and grim.

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.
