The Lowdown
Howdy, Rusty here again. Let’s be real, Blacks Beach is looking like a total dud for the next 16 days. The first week, from Thursday, July 30th, through the early part of August, there’s nothing. The swell is ankle to knee-high, at best 0.9 ft, and the wind is garbage—blowing onshore or cross-onshore out of the west. The combined wave energy is weak, in the hundreds (391), and it’s all "poor surf conditions." Not worth waxing the board.
Into the second week, around August 7th and 8th, the swell tries to show up with a reading of 0.8 ft but with a very long period of 19 seconds from the SSW. That energy is moderate (481), but it’s a beach break with a cross-onshore wind. That long period stuff is just going to close out or be a bumpy mess. The water temp is about normal for this time of year.
The only flicker of hope is on Monday, August 10th, in the morning. The wind goes light and cross-onshore, and the swell is a tiny 0.8 ft. The guidance rates the break highly, but the forecast is a 1/10. It’s a “marginal” call—maybe you’ll find a clean-ish, waist-high wave if the tide works. But after that, it’s back to flat and windy. For a spot that’s usually consistent, this is a real bummer. Just one of those stretches where the ocean says, “Not today.”
Stay patient.

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.
