Hey, Rusty here.
Look, I’ve gotta level with you—this is a pretty bleak run for Blacks Beach. The whole 16-day window is mostly flat or poor quality, and there’s a quiet start. The first real chance is Sunday the 5th, but even then it’s a toss-up.
Alright, here’s what’s cooking.
Sunday morning the 5th, we’re looking at about 3 feet of swell from the SSW, but check the period—18 seconds, that’s proper groundswell, deep and powerful. Combined swell energy is 515, so moderate. Waves that long can be a bit straight at a beach break like Blacks, but the wind is blowing offshore out of the west at 15 km/h, so the faces should be clean. The report flags marginal conditions with tricky tides, so it’s a gamble, not a guarantee. Water temp is about normal for this time of year.
Sunday afternoon the 5th drops to 2 feet and the wind goes cross-onshore—choppy and no good.
Monday the 6th morning has 3 feet again, same SSW direction, 16-second period, still offshore. Energy hits 529, but it’s marginal. Monday afternoon jumps to 742 energy but the waves are poor—wind stays on, quality’s off.
Tuesday the 7th morning brings 3 feet, 18-second period, 859 energy, but it’s poor with onshore wind. Tuesday afternoon is marginal at best.
Wednesday the 8th morning has 4 feet, 16 seconds, a light cross-onshore breeze, and 840 energy—moderate-to-strong but still marginal. Wednesday afternoon is similar with 772 energy and a low score.
Thursday the 9th stays stuck around 3 feet, 16 seconds, with cross and cross-onshore winds, energy around 724—marginal.
From Friday the 10th, it’s all downhill. Swell fades, periods shorten, wind stays messy. By Sunday the 12th we’re at 3 feet with a 14-second period and cross-onshore wind—energy under 322, poor.
Wednesday the 16th morning gives a brief bounce to 4 feet from the west at 9 seconds with light wind, but the period’s short and the waves are poor. After that, it’s more low-energy, poor conditions through Monday the 20th July, where it bottoms out at 2 feet and a combined energy of just 74.
The best you’re gonna get is Sunday morning the 5th—that long-period groundswell with offshore wind could give a few clean ones if you nail the tide. But it’s nothing to write home about. For the rest, the wind’s cross-onshore a lot, and with such weak surf, you might see more kite surfers than paddle surfers out there.
Stay patient. Forecasts change.
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.
