The Lowdown
Alright, Rusty here again. Let's break down the same outlook in feet and knots.
It's a tough outlook, my friend. The only spot in the data is Birdrock, which is an advanced reef break that's inconsistent. It's exposed to the swell, but the wind is almost always cross or on it, which is a recipe for a messy wave. The water is running 4° warmer than usual for this time of year, which is very unusual, so it's gonna be a warm one.
The first few days are a washout. There is nothing to recommend for Tuesday, August 4th, or Wednesday, August 5th. The swell is tiny, around 2 to 2 feet, and the wind is from the wrong direction. The combined energy is weak, sitting between 130 and 193 (weak to moderate wave energy). It's not worth a look.
Thursday, August 6th, through the end of the first week stays the same. Swell sticks around 2 to 3 feet, with moderate energy readings. The wind is still cross-on, making it choppy. The period is 13 to 16 seconds, which is a decent groundswell, but the size is just too small to overcome the wind.
Moving into the second week, from Monday, August 11th, the swell tries to build. The combined energy climbs into the 300s and 400s, but the wind stubbornly stays cross-on. Friday, August 14th, shows a jump in energy to 580 (strong wave energy) with a 2-foot swell from the SW, but again, that cross-on breeze from the W is going to ruin it.
The one day that might be worth a look is Saturday, August 15th. The swell pushes to 4 feet from the SW, with a solid 16-second period and strong energy readings around 600. The wind is still cross-on from the WNW, which is a little cleaner than a direct onshore but still not clean. It's only rated as marginal. This is a bigger groundswell, so the reef could produce some shape, but the wind is going to be the main issue. It's a long shot.
For the rest of the run, it's the same story: small, messy surf with cross-on or onshore winds. The swell period is long, meaning there's energy out there, but the direction and wind just aren't lining up for a good session at Birdrock. If you're really keen, maybe check that Saturday, August 15th, but don't get your hopes up. The setup might be better for a kite than a paddle.
Rusty out.

Information about the Birdrock Surf forecast
The above surf forecast table for Birdrock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Birdrock can be found by selecting the local surf guide option on the grey menu. Our Birdrock 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 (Birdrock) 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 Birdrock 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.
Birdrock is 10 km (6 miles) from 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.
