The Lowdown
Alright folks, Rusty here. Let’s get into it. This outlook is all about Blacks Beach, and it’s a bit of a mixed bag. We’ve got a solid long-period groundswell on the way, but the wind is going to be a nagging issue for most of the run. The real standout window is a few days out, but patience will be the key.
First up, we’re looking at a long-period swell coming from the SSW. The water is sitting at a very unusual 74°, which is much warmer than normal for this time of year. You can leave the 4/3 at home for this one.
Tuesday, July 21st kicks things off, but it’s a bit of a tease. The morning has a clean 3ft swell from the SSW with a very long period of 16 seconds, and a light WSW breeze (10 km/h) blowing offshore. That’s a recipe for some clean, lined-up waves to start. The combined energy is moderate at 744. Afternoon, though, the wind swings onshore from the WNW at 20 km/h and the surf quality takes a nosedive.
Wednesday, July 22nd is a write-off. The cross-onshore wind from the WNW at 15 km/h will have the surface chopped up. The swell is still there at 3ft but the conditions are just poor.
Thursday, July 23rd is a weird one. The swell drops to 4ft from the W, but with a short, crumbly period of 7 seconds. That’s nothing to get excited about, and it’s blown out by the afternoon. The afternoon swell drops to 1ft, but with a 26-second period. That’s an incredibly long period, but with no height and onshore wind, it’s a non-starter.
Friday, July 24th through Sunday, July 26th is a slow grind. The swell size hangs around 2ft to 4ft, but the wind is a persistent cross-onshore, keeping the surface choppy. The energy is moderate, hitting 889 on Friday morning and climbing to 1046 on Saturday morning, but it’s just not clean enough to call it a good session.
Now, here is the window we’ve been waiting for.
Monday, July 27th is the pick of the week. The morning has a 4ft swell from the SW, but the real story is the afternoon. We get a 4ft SSW swell with a 19-second period, cross-onshore breeze from the SW at only 10 km/h. The combined energy hits a strong 1366. That’s a lot of water moving. The wind is light, the swell is clean, and the long period means the waves will have plenty of punch. The conditions are marginal on the scores, but with that light wind and solid energy, the lines will be there. This is your best shot.
Tuesday, July 28th continues the trend. The morning has a 4ft SSW swell, 17 seconds, with a light cross-shore wind from the SSW at 10 km/h. The energy is still strong at 1163. It’s a touch more wind-affected than Monday, but still a solid option.
Wednesday, July 29th is still workable, but the energy is dropping off. The swell is 4ft to 4ft, and the wind is a light cross-onshore. It’s not the standout, but it’s better than the previous week.
From Thursday, July 30th onward, we hit a dry spell. The swell drops away, the wind turns onshore, and the combined energy falls to weak levels. The surf is poor to flat from July 30th all the way through the end of the run on August 5th. You’ll be looking at blank, small waves with onshore wind for the best part of a week.
So, to wrap it up: The standout is the afternoon of Monday, July 27th. That 4ft, long-period SSW swell with very light wind is the one to circle. Tuesday morning is also a solid back-up. After that, be prepared for a long stretch of nothing.
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.
