The Lowdown
Alright, grab your coffee, surfers. Rusty here. Let's be honest up front: this 16-day window for Terra Mar is a tough one. We're looking at a long stretch of onshore and cross-onshore winds that just won't let up, and the swell is small and weak. The water is a warm 75°F right now, which is much warmer than usual for this time of year—that's a crazy 8°F anomaly, so you won't need a wetsuit, but the conditions are a real letdown.
The first few days are a write-off. Friday the 7th and Saturday the 8th are clean and clear skies, but the wind is a cross-onshore, the swell is a tiny 2ft to 3ft, and despite that long period of 19 seconds from the SSW, the energy is weak (449) and the surf is just poor. There's nothing to recommend.
Sunday the 9th through Thursday the 13th see the wind switch to onshore, still light to gentle, but the swell stays small, under 3ft, with moderate energy (300s to 400s). The surf is still "poor." It's a grim run. Tuesday afternoon the 11th is the first time we see a "marginal" rating, but it's a 2ft onshore wind swell with a score of 1 out of 10. Not worth a paddle.
The second week doesn't get much better. Friday the 14th and Saturday the 15th have a bit more energy (553 to 762), but the wind is still cross-onshore, and the swell is only 3ft to 4ft. The period drops to 16 seconds, and the surf is still "marginal" at best. The best chance in the whole outlook might be that Saturday afternoon the 15th, with 4ft SSW swell, gentle cross-onshore wind, and moderate energy (762). It's not clean, but it's the biggest and most energetic we get.
From Sunday the 16th all the way through to Saturday the 22nd, it's the same story: cross-onshore winds, 3ft to 4ft swell, moderate energy, and poor to marginal conditions. The last Saturday the 22nd has a light breeze and 3ft swell with 14-second period and moderate energy (581), but it's still cross-onshore.
Honestly, there's no standout session here. The swell is too small for the wind to be a problem, and the wind is always wrong for good shape. For a point break like Terra Mar, which needs the right swell direction and light wind, this is a total dud. If you're desperate, maybe the Saturday afternoon the 15th offers the most push, but it's not going to be a pretty wave. This setup looks more interesting for kite surfing than paddle surfing, if you're into that.
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.
