The Lowdown
Right, let’s have a look at what’s on offer for Terra Mar. This is a beginner point break exposed to a WSW swell, and it’s fairly consistent. Some of those clean windows might just line up.
Right now, through the end of August, it’s a bit of a write-off, I’m not gonna lie. We’ve got small swell, mostly under 3ft, and the wind is onshore or cross-onshore from the WSW and SW. Makes for poor conditions and a choppy surface. The water is sitting at 74°, which is a solid 6° warmer than usual for this time of year – that’s very unusual, so you’ll feel that bathwater. But it’s not enough to save a flat, messy surf. The combined swell energy is weak to moderate, hitting around 340-400, but there’s just no quality.
Into the last few days of August and the first day of September, we see a bit of a lift. The swell starts to nudge up to 4-5ft, with a period around 12-13 seconds. That’s a proper groundswell, and it gives the waves some shape. But the wind stays cross-onshore or onshore for most of that, so it’s still marginal. We get a glimmer on the 31st with some light NE offshore wind in the morning, but the swell drops to 3ft and then keeps fading. Not the best.
Now, the first standout of the window shows up on Tuesday, the 1st of September. A morning session with light offshore NE breeze at 9 mph, cleaning up a 4ft S swell, 12-second period. That’s going to produce clean, rideable waves. The combined energy is moderate at 564. This is the pick of the first week. Beginners, take note – it’s small enough to learn on, but the offshore wind will make it tidy. That afternoon gets some rain and a bit weaker, but still good.
Into the 2nd and 3rd of September, it gets messy again. Wind flips around to WNW and WSW, putting us on a cross-on breeze. The swell stays around 4ft, but the quality drops. By the afternoon of the 3rd, though, we see the combined swell energy jump to 1028 – that’s strong wave energy – with a 3ft SSW swell and a very long 19-second period. That’s a lot of push for such a small face, and at a point break, those long lines will wrap in nicely. The wind is still light cross-onshore, so it’s a bit bumpy.
The second big standout is Monday, the 7th of September. In the afternoon, the wind goes glassy – absolutely dead calm – and we’ve got a 2ft SW swell with a 21-second period. That’s incredibly long-period groundswell, the kind that wraps deep and lets you down the line. Combined energy sits at 604. For a point break like Terra Mar, that’s a dream combo, even if the wave height is tiny. That is the session to mark on your calendar.
After that, a bit of a pulse on the 8th, but with southerly wind kicking up, it’s messy again.
Overall, if I had to pick two standouts: the morning of Tuesday, 1st September for clean, offshore conditions on a fun 4ft S swell; and the glassy afternoon of Monday, 7th September for that magic, long-period SW groundswell.
Stay keen.

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.
