The Lowdown
Alright folks, Rusty here. Let's have a look at what Terra Mar's got cookin' over the next couple of weeks. I gotta be straight with you, it's a pretty flat and frustrating picture for a while.
The near term is a total washout. We're looking at a long, quiet stretch from Wednesday the 5th of August right through to Thursday the 14th. That's over a week of nothing but "poor surf conditions" with very low scores. The swell is tiny, mostly around 2ft to 3ft, coming from the SW or SSW. The real killer is the wind. It's mostly cross-onshore from the WSW, turning what little bump there is into choppy, wind-affected junk. To make matters worse, the combined swell energy is moderate, hovering in the 100s to low 400s for most of that time—just enough to stir it up, not enough to surf. Don't even bother paddling out.
Now, there is a glimmer of hope as we push into the second week. The forecast starts to get more interesting from Friday the 14th of August onwards. The swell is still modest, but it builds slightly, hitting around 3ft to 3ft from the SSW. The wind also backs off a bit, going lighter cross-on from the WSW. This is when the "marginal" calls start popping up, with scores of 1 out of 10, which is a big step up from the zeros. Saturday the 15th of August into Sunday the 16th looks like your best chance, with some 3ft SSW swell and clean enough looking light cross-onshore breeze.
The only true standout in this whole outlook is Terra Mar itself. It's a point break that's fairly consistent and gets a WSW wind as its offshore, but we're not getting that here. For this brief window around the 15th and 16th, the light cross-onshore conditions will be rideable, especially as a beginner-friendly spot. The swell will be a manageable 3ft from the SSW, with periods around 15 to 16 seconds—giving the waves some decent long-period power and shape for a point break. The combined energy jumps to a strong 538 to 642, showing there's a bit of push.
Don't get your hopes up too much for a classic session, but if you're jonesing for a wave, Saturday the 15th of August is your day. Just be aware it’s a beginner-friendly wave, so crowds are possible, especially on a weekend. The water temp feels about average for this time of year.
Stay patient.

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.
