The Lowdown

Alright, let's be straight with you. This stretch is going to test your patience more than your paddle. The first few days are dead flat, lifeless, not worth the rubber. You're looking at over a week of weak leftovers and onshore junk before we get a whiff of anything decent.

From the 15th through the 18th, it's a total washout. We've got 2ft of short-period slop, and the wind is cross or straight onshore. It's chopped, weak, and just plain ugly. The energy is weak, with readings like 274 and 360, meaning there's barely enough push to get you down the line. Don't bother. The water is a warm 73°, which runs about 5° warmer than it should be – that's some unusual stuff, but it won't save the surf.

Things start to lift a little from the 19th, but it's still marginal. We get a bit more swell, up to 3ft, and the energy climbs into the 500s and 600s. But the wind is still on it, and conditions are just questionable. It's not terrible, but it's not good. You'll be fighting for a grovelly, gutless wave. The swell is from the SW, which is a direction Blacks Beach (San Diego) likes, but the quality just isn't there.

The 21st and 22nd see the swell bump up, hitting 3ft to 4ft with periods around 17 seconds. That longer period is a hint of some better groundswell. There’s more juice in the water, with energy readings over 700. But the wind is still not playing nice. It's mostly onshore, so it'll be lumpy and hard to find a clean face. It's the best of a bad bunch, but calling it a standout would be a fib.

After that, we slide back down. From the 23rd onward, it's a slow fade into the poor category again. The swell drops back to 3ft before fading to 3ft and then 2ft by the 28th. The energy levels sink back into the 100s and 200s. That longer period swell is a distant memory. It's back to being small, weak, and mostly messy.

Honestly, for this area, a blank stretch like this isn’t unusual. But when you see those few days around the 20th and 21st where the swell and energy are building, you know it won’t stay this poor for long. Forecasts can change. But right now, don't get your hopes up. There’s nothing here that gets the heart racing.

Stay patient. 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.
