The Lowdown

Alright, surfers, Rusty here. Let's have a look at Blacks Beach. We've got a real flat spell coming up, so don't be in a rush.

First off, the water temperature is about average for the time of year, so nothing too wild to worry about there.

The whole 16-day window is looking pretty grim. We kick off Monday the 31st of August with a tiny 3 ft swell from the SSW, but the wind is onshore and it's just poor surf. That sets the tone for the next week. Tuesday, Wednesday, Thursday... it's all small, messy, and onshore. The energy is weak, with combined energy readings mostly in the low 100s to 400s, which is just not enough to get excited about.

We get a bit of a tease on Wednesday the 2nd of September morning with a 2 ft swell from the SW, but it's a very long 16-second period, which is a groundswell. That long period is more suited for a point or reef, but at a beach break like Blacks, it can break too straight and won't have any push. That afternoon the swell bumps up to 3 ft, but the energy jumps to 429, and it's still onshore and poor.

Thursday the 3rd of September afternoon kicks up a bit, with a 3 ft swell from the SSW and a very long 18-second period, pushing the combined energy to 746. That's moderate energy, but it's still onshore and marginal at best. The wind is a gentle breeze, but it's onshore, so it's not clean. The same pattern holds through Friday and Saturday: small, marginal, cross-onshore winds.

Then we hit a real lull. Sunday the 6th of September is a write-off with heavy rain, strong winds, and a tiny 2 ft windswell from the NW with a 4-second period. The energy is only 16 – that's basically nothing. That trend continues into Monday the 7th, with even smaller waves and onshore winds.

There's a small blip on Tuesday the 8th of September morning. The swell picks up to 6 ft from the SSW with a 9-second period, and the combined energy hits 732. But the wind is onshore from the WNW, and the quality is still marginal. That afternoon it drops back to 5 ft and the energy fades to 438. It's not the clean, groomed swell we want.

From there, it's back to the same story. The rest of the window through to the 15th of September is all small, weak, onshore, and poor surf. The energy readings are in the 100s to 500s, and it's consistently described as "poor surf conditions" or "marginal." Consistency is rated as "consistent" for the spot, but the quality just isn't there.

Honestly, there's no standout here. There's nothing worth paddling out for. The best you could hope for is a half-hearted session on the 8th of September morning, but even that is a long shot with the onshore wind. For a spot that's normally exposed to W-NW swells, we're getting mostly SSW windswell, which is the wrong direction. The wind is almost always onshore or cross-onshore, which just ruins it.

If you're into kite surfing, the stronger wind days might be more interesting, but for a paddle surfer, this is a full-on blank run. It's a tough stretch, but it happens. Forecasts can change, so keep an eye on it, but for now, save your energy.

Stay tuned, and I'll keep you posted.

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.
