The Lowdown
Alright, surf’s up, or at least it’s trying to be. Let’s talk about the next couple of weeks at Terra Mar. It’s gonna be a patchy run, with a whole lot of nothing to start, so don’t go rushing out the door just yet.
The first few days are looking pretty grim. We’ve got some small, weak swell on the cards, but it’s coming in from the SSW and SW, which is just about the worst direction for this spot. The water’s a touch warmer than normal for this time of year, which is nice if you’re in it, but it won't help the waves. The wind is light, but it’s onshore, and that’s enough to kill any real potential. For the first few days, it’s a flat, mushy mess.
Wednesday the 11th and Thursday the 12th are going to be poor. We’re looking at small, weak swell, with light onshore breezes. The combined energy is weak, with readings in the 200s to 400s. It’s just not worth the paddle. The swell is there, but it’s gutless and messy. It’s the kind of day you’d rather be doing something else.
Heading into the weekend, the 14th and 15th, we see a slight bump in size, up to 3ft, but the quality just isn't there. The wind keeps flirting with cross-onshore, and the swell is still coming from the wrong direction. You’re looking at a lot of closeouts and no real push. The energy picks up a bit, around 500 to 600, but it’s not enough to overcome the conditions.
The real window, if you can call it that, starts to show up around Wednesday the 16th. The swell, still from the SSW, pushes up to around 3ft and the period stretches out to 17 seconds. That’s when things might get a little more interesting. The energy starts to climb into the 500s. The wind is still cross-onshore from the west, which is a bit of a bummer, but the waves should have a bit more shape to them. It still won't be clean, but it’ll be the best of a bad bunch.
The following week, things stay in that same zone. We’re not talking about anything big, just a more consistent push of chest-high, sloppy surf. The second week, the 19th through the 22nd, sees a more consistent shoulder-high swell, with energy getting up into the 600s. The winds are light, but they remain onshore or cross-onshore. It’s going to be a bit of a grind. The periods are still long, around 18 seconds, which is a plus for shape at this point, but the direction just isn’t ideal.
Honestly, the standout day looks like Monday the 21st. The swell is up to 4ft from the SW, with a period of 17 seconds, and the energy is at its highest, hitting 679. The wind is light, but still cross-onshore. It’s not going to be perfect, but for this stretch, it’s probably the best you’re going to get. It’s a small window, and the quality is still marginal.
That's about it for the next two weeks. There’s no big swell coming, and the wind is never going to be truly offshore. It’s a grind for the dedicated, and a pass for the rest of us.

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.
