The Lowdown

G'day, I'm Rusty. Let's have a look at the 16-day outlook for Blacks Beach.

Honestly, the next week and a half is a bit of a struggle. We've got a real slow patch here. The first few days are chopped up with cross-onshore winds and poor conditions, and the surf quality is just not there. It's not until we get into the second week that things start to look a bit more promising with cleaner conditions.

The water temperature is 72°F right now, which is a very unusual 4°F above the norm for this time of year. It feels like a warm bath out there.

For the first real standout, you've got to wait until Wednesday, September 16. The morning session is the pick of the early period. We're looking at a 3ft SSW groundswell, with a very long period of 17 seconds. That long period means the wave energy is solid, with a combined energy of (638). The wind is light and cross-onshore from the WSW, creating only small wind ripples, so the surf will be clean. This long period, straight south-west swell can be a bit tricky at the beach break, but the quality will be there.

Then, the real highlight of the whole outlook shapes up for Sunday, September 20, and Monday, September 21. Sunday morning sees a 3ft SW groundswell, with a massive 19-second period. The combined energy jumps to (734), which is the strongest we see in the whole forecast. The wind is light cross-onshore from the WSW, keeping it clean. Then Monday morning is even better, with a 4ft SW swell at 17 seconds, and the energy hits (755). The wind is the same – light cross-onshore from the WSW. These are the best days on offer. The swell is still small, but that long period will give it a lot of push and shape. It's a spot that's consistently exposed, so it'll catch it.

The winds look like they'll be offshore on a few mornings, especially around Wednesday the 9th and Wednesday the 16th, which is a major positive for clean conditions. It's a consistent break, but it can get crowded often, so be prepared for a few heads in the water.

So, to sum it up: the first week is a write-off. The best windows are Wednesday, September 16, with a solid morning, and then the standout is the Sunday, September 20 and Monday, September 21 window. Those are your best bets for a proper surf. The long-range stuff is a bit more of a gamble, but the models are liking it.

Stay stoked, and I'll see you out there.

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.
