The Lowdown
Alright, Rusty here. Let’s talk about the coming days at Terra Mar.
Right off the bat, we’ve got some swell on the way, but it’s a bit of a mixed bag with the wind. On Sunday afternoon, the 6th of September, we see a 5ft S swell with a solid 13-second period pushing in from the south. The water is sitting at 73°, which is much warmer than usual for this time of year—that’s a nice treat. The wind is a moderate 12 mph from the north, blowing cross-offshore, which keeps things clean. The combined energy from all swells is strong (1310), so there’s some push. The rating is only a 3, so it’s not a standout, but it’s the best on offer early on. It’s a beginner-friendly point break, and this wind is a big positive for getting some clean, rideable waves.
Monday morning the 7th of September, the swell is a bit bigger at 6ft from the SSW, still a 13-second period, but the wind swings to the WNW at 9 mph, turning it cross-onshore and making it fairly choppy. The combined energy stays high (1098), but the quality drops. The wind gets worse in the afternoon, picking up to 16 mph, and the surf goes poor. That’s a no-go.
Tuesday the 8th offers a smaller 4ft SSW swell with a 13-second period, but the wind is still cross-onshore and choppy. The combined energy is moderate (721). Not worth paddling out.
Now, here’s a little glimmer: Wednesday afternoon the 9th of September. The swell is tiny at 2ft from the SW, but the period is a very long 16 seconds, a true groundswell. The wind is glassy—dead calm—and the combined energy is moderate (431). It’s small, but for a point break, that long period can mean some clean, lined-up waves. It’s a beginner break, so if you’re learning, this is about as easy as it gets. The caveat is that long-period swells like this can break a bit straight on beach breaks, but at a point, it should wrap in nicely.
After that, the surf drops off significantly. From Thursday morning the 10th of September through the entire second week, the swell stays under 3ft for most of it, with the wind consistently cross-onshore or onshore. The periods are all over the place, but the combined energy never gets above 700, and most days are rated as poor or marginal. There’s a small nudge on Monday the 21st of September, with a 4ft swell from the SW at 17 seconds, and the combined energy climbs to 784 (moderate), but the wind is onshore or cross-onshore, so it’s messy. The forecast is too far out to trust completely, but it doesn’t look promising.
Overall, the best window is the Sunday afternoon the 6th and Wednesday afternoon the 9th. The Sunday is the strongest swell, but the Wednesday is the cleanest. Neither is a huge standout, but if you’re itching for a session, those are the picks. The rest of the 16 days is a long, quiet stretch with no real options.

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.
