The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the coming weeks.
We're looking at a long stretch of small, clean but underwhelming surf with a few windows where conditions could be worth a paddle. The standout day across the whole forecast is Saturday the 19th of September, with a couple of days either side also worth a mention.
Let's start with the most interesting run. Through the first week, the swell is tiny, the winds are mostly cross or cross-onshore, and the wave energy reading is moderate but the quality just isn't there. The real promise kicks off around Thursday the 18th of September. On the morning of the 18th, we've got a tiny 2ft swell from the SW with a very long period of 19 seconds, and light offshore winds from the west. The combined energy is moderate at 521. The water temperature is about 72°F with an anomaly of 4°F, so a touch warmer than normal. It'll be clean but small.
Then we get to the best of the bunch: Saturday the 19th of September. The morning session at Blacks Beach sees a clean 3ft SW swell, period of 18 seconds, and light offshore winds from the west. The combined swell energy is solid and moderate at 608. That's the best energy reading in the whole outlook. The long period groundswell will wrap in nicely here, providing some shape. The water is still that warmer than average temp. It's a spot that can get crowded, so be prepared to share the peak.
The wind looks likely to swing a touch cross-on by the afternoon, but the morning window is the pick. The day before, Friday the 18th, also has clean but smaller surf in the morning. The following couple of days, Sunday the 20th and Monday the 21st, stay in the marginal category with similar small swell (3-4ft) and mostly light winds, but the energy dips slightly and the wind direction isn't as ideal.
Before that, from the start of the outlook right through to the 17th, it’s mostly poor to marginal conditions with tiny swell and poor wind angles. There's a real dry spell for quality waves.
So, to sum it up: the best bet is the morning of Saturday the 19th of September at Blacks Beach. It won't be big, but it will be clean with a decent long-period groundswell and the best energy of the whole run. Get in before lunch.
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.
