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 next couple of weeks.
First off, I gotta be straight with you – it’s a tough stretch. The water temp is sitting at 72° and running 6° warmer than usual for this time of year, which is very unusual and makes for a weirdly warm feeling paddle out, but it’s not helping the surf.
The whole 16-day window is a real grind. From the start of the forecast right through to the end of the month, there’s nothing that really gets the heart pumping. We’ve got a long gap here with no solid recommendations. Honestly, the first couple of weeks are pretty much a write-off for decent waves.
The only consistent spot on the map is Blacks Beach. It’s an exposed, advanced wave that handles a WNW direction best, but the swell we’re looking at is coming mostly from the SSW and SW. Over the whole period, the swell heights are mainly in the 2 ft to 3 ft range, which is small. The combined energy is moderate, bouncing around between 216 and 560 (moderate wave energy), but it’s not enough to make anything worthwhile.
The real killer is the wind. It’s almost always cross-on or onshore, mostly from the SW or WSW at 6 to 9 mph. That’s going to keep things choppy and messy. There are a few brief moments with lighter winds, like on Sunday the 12th morning with a light cross-on at 3 mph, and a few onshore windows with light breezes, but the swell is just too weak and the conditions are still poor or marginal. The periods are long, mostly 13 to 18 seconds, and occasionally hitting 19 to 24 seconds – that’s proper groundswell, but it’s just not wrapping in right for this break. Long period swells like this can be tricky at beach breaks, making them break straight, and Blacks is a beach setup, so that’s a caveat.
There’s a tiny uptick around the 18th and 19th of July, with swell hitting 3 ft to 3 ft from the SW, and the energy pushing into the 530-560 range, but the wind is still onshore or cross-on. It’s a marginal surf forecast at best, and I wouldn’t call it a standout. Warm water, small swell, and persistent chop – it’s a bit of a grim outlook for paddling. If you’re a kite surfer, the consistent cross-onshore winds and small, choppy waves might look interesting, but for a surfer, you’re better off waiting for a better forecast.
So, bottom line: there are no good surf options in this 16-day window. The area is just on a blank run. It tends not to stay poor for long, but this one’s a doozy. Forecasts can change, so keep an eye out, but for now, I’d hang the board up.
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.
