Table - best surf conditions forecast for Blacks Beach over the next 16 days.
Alright folks, Rusty here. Let's have a look at what’s on the cards for the coming weeks.
Right off the bat, I gotta be straight with you – this isn’t a classic run for our stretch of beach. We’re looking at a long, slow patch with no real standout sessions. The swell is small and the wind is just never giving us a proper clean break. The first few days are a write-off, with cross-onshore breezes messing up what little energy we have. We’re talking about a gap of quiet, poor conditions stretching from the start all the way through the first week.
Blacks Beach is the only break on the radar here, and it’s exposed to the swell, but the direction we’re getting from the south-southwest isn’t playing nice with the optimum WNW. The water temp is about average for this time of year, nothing wild.
Let’s walk through it. Saturday the 11th and Sunday the 12th of July? Forget it. We’ve got a 3ft swell from the SSW with a promising 15-second period on Saturday, but that cross-on 9 mph wind is just chopping it to bits. The combined energy is moderate, but the waves are poor. Sunday morning is a bit better with lighter wind and 3ft, but it’s still marginal at best. Monday the 13th is much the same – small, weak, and cross-on. This pattern just repeats day after day. The swell sticks around 2ft to 4ft through the whole run, but the wind keeps switching between a light cross-on or onshore breeze, never giving us that glassy offshore moment we need. The period is often long, in the 13 to 19 second range, which is nice for better shaped waves, but with the wind wrong and the size so small, it’s not doing us any favours.
Honestly, there’s not a single day in this whole 16-day window that I’d call a standout. The best you can hope for are a few marginal moments on Sunday morning July 12th, or Wednesday morning July 15th, where the wind is light and the swell is tiny but clean-ish. But it’s not worth getting excited about. If you’re an advanced surfer looking for some real power, you’ll be disappointed; the biggest swell is about 4ft on Sunday the 26th, but that has a short, choppy 8-second period and onshore wind – a total mess. The energy levels bounce around from weak to moderate, but the quality just isn’t there.
So, what’s the call? This is a quiet period for Blacks Beach. The setup is more interesting for a kite surfer than a paddle surfer on most days, given the consistent cross-onshore wind and small, choppy waves. Keep an eye on things – it’s not always this flat and messy, and forecasts can change. But for now, save your wax.
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.
