The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’re looking at Terra Mar, a point break that’s fairly consistent. Right now, the water is sitting at 77° – that’s much warmer than normal for this time of year, so you can leave the booties at home.
We start off on Saturday afternoon, August 29th with a 4ft SSW swell. The period is a juicy 16 seconds, which is groundswell, so there’s plenty of energy in the water. The combined swell energy is 692, which is solid. But here’s the rub – the wind is cross-on from the W at 9 mph, keeping it a bit choppy. It’s rated as marginal, so it’s not a total write-off, but you’ll be working for the good ones. If you’re a beginner, this is doable; the swell is under 5ft.
Sunday morning the 30th is a no-go – onshore wind kills it. Sunday afternoon is also marginal. Monday the 31st is a similar story: small swell and cross-on wind.
We go through a stretch from Tuesday, September 1st, right through to Thursday, September 3rd, where the surf is just poor. Small chop, weak energy, and the combined swell energy drops to the low 300s and 400s. This is a gap of a few days where you’re better off doing something else.
Friday, September 4th, there’s a little flicker of life. Morning has a 3ft SSW swell, 17-second period, but the wind is onshore. The combined energy hits 847, which is getting into the moderate-to-strong range. Still, it’s marginal. The best we’ve got in this first week is Saturday, September 5th. The swell holds at 4ft from the SSW, with a 16-second period. The wind is light cross-on from the W at 6 mph. The combined energy is 750. It’s still not perfect, but it’s the most consistent and cleanest we see for a while. Expect some crowds though – this spot is a point break and can get busy.
Now, into the second week. The standout is Tuesday, September 8th. We’ve got a 7ft SSW swell with a 13-second period pushing through. The combined energy jumps to 1547 – that’s strong. This is expert territory, over 8ft, so only for the experienced crew. The wind is still cross-on at 9 mph, so it’ll be a bit lumpy, but the power is there. This is the best wave of the forecast period, but it’s a long way out, so keep an eye on it.
After that, Wednesday and Thursday the 9th and 10th drop off again. The swell period shortens, the energy fades, and the wind picks up. It’s fair to say the setup looks more interesting for kite surfing than paddle surfing on those days.
We finish out the forecast with a small bump on Sunday, September 13th – 4ft S swell, 14-second period, 675 combined energy. Wind is light cross-on, so it’s worth a look if you’re desperate, but it’s not the highlight.
So, if you’re asking me, the best on offer is Saturday, September 5th for the average surfer, and Tuesday, September 8th for the big-wave hunters. The rest is a lot of waiting.
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.
