The Lowdown
Alright, Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty bleak for any real waves. There's a stretch where you'll be wondering if the ocean still works. We're talking no good options from now until basically the end of August. That's a solid 4-day gap of flatness. Don't even bother with the wax.
Things start to stir just a little as we hit the weekend of the 29th and 30th. There's some swell, but it's weak, and the wind is mostly cross-onshore, leaving things a bit lumpy. Not what you're after.
Now, the one true standout in this whole window is Tuesday, September 3rd. Out of nowhere, the energy picks up huge. The combined swell energy is hitting 1496 in the morning and 1625 by the afternoon – that's strong, powerful stuff. The surf is gonna be a solid 7ft with a period of 12-13 seconds, so there's some real punch behind it. The problem? The wind is cross-onshore, so it won't be perfect, but it'll be the biggest and most consistent surf of the fortnight. Terra Mar (San Diego) point is the place. It'll hold that size well. It's not a total classic, but it's the only day that comes close to lighting up. This is too much for beginners, but for the experienced crew, it's your window. After that, things fade fast, and the second week is a snoozefest of waist-high slop and onshore winds.
Water temps are about average for this time of year, so a shorty or spring suit will do.
The following week has a sliver of hope. On Sunday, September 8th, there's a bit of a reprieve. There's a 3ft SSW swell filling in, but the wind is forecast to be glassy – a huge positive. It won't be big, but it could be clean and fun on the point. That's your only other good look. The rest of the week is just small, cross-onshore dribble.
Bottom line: don't bank on much. Mark your calendar for the 3rd of September for the biggest day, and maybe the 8th for a clean if small one. Everything else is a skunk waiting to happen.
Rusty.

Information about the Terra Mar Surf forecast
The above surf forecast table for Terra Mar provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Terra Mar can be found by selecting the local surf guide option on the grey menu. Our Terra Mar 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 (Terra Mar) 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 Terra Mar 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.
Terra Mar is 1 km (1 miles) from the city of Oceanside. If you plan a vacation in San Diego County, look for hotels and other accommodation in Oceanside. Oceanside has rooms for a wide range of budgets as well as car hire and transport links.
