The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Terra Mar.
The window opens up this Sunday morning, the 6th of September, with a solid pulse of S swell at 6ft. The period is a juicy 14 seconds, which is proper groundswell. The wind is a clean N at 15 km/h, blowing cross-off, and the wave state is clean. The water temp is sitting at 73°, which is 5° warmer than normal for this time of year – that's a very unusual spike, so you might want to leave the 4/3 at home and bring a thinner suit. The combined swell energy is sitting at 1330, which is strong wave energy. The swell direction is from the S, and the optimum for this point break is WSW, so it's not a perfect match, but there's enough power to get it working. This Sunday morning is your standout window: decent size, clean conditions, and that long period will wrap nicely around the point. It's a beginner-friendly break and fairly consistent, so it's not too hectic, but with that quality, crowds are possible.
Sunday afternoon takes a turn with light rain and a stronger NNE wind at 25 km/h going offshore, but the swell drops to 5ft. Still good for experienced surfers, but the morning is definitely the pick.
By Monday the 7th, the wind swings to the WNW and goes cross-on, which messes with the shape. The swell holds around 6ft, but it's choppy. That trend continues through Tuesday and Wednesday, with the swell fading and the wind staying onshore or cross-onshore. The wave energy drops into the moderate range (797 down to 418). It's not looking good for paddle surfing.
We hit a real dry spell from Thursday the 10th through to around the 15th of September. The swell is small, the wind is mostly cross-on, and the wave energy is weak (down to 196). For a point break like Terra Mar, this is a blank run that's not unusual for the area, but it doesn't mean it stays poor forever – forecasts can change.
Things start to show a little pulse again around Tuesday the 15th of September. The period jumps up to 20 seconds – that's very long period groundswell – but the swell height is only 2ft, so the energy is weak (484). That kind of long period at a point break can be good for shape, but you need some size to work with. Wednesday the 16th and into the following week shows some small pulses of SSW swell around 3ft to 3ft, with light winds, mostly cross-on. The wave energy climbs back into the moderate range (511 to 626) by the 19th and 21st of September. The standout in this second week is probably the morning of Saturday the 19th of September, with a clean 3ft SW swell at 18 seconds and a light cross-on wind. The swell direction (SW) is closer to the optimum (WSW) than the earlier S swells, so it should wrap in nicely. That's a promising long-range prospect, but less certain.
All in all, the best on offer is Sunday morning, the 6th of September. Get on it early.
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.
