The Lowdown

Alright, surfers, it's Rusty here. Let's get stuck into the outlook for Terra Mar. It's a bit of a flat spell we're looking at, so strap in.

Right now, the water is sitting at a toasty 72°, which is a touch warmer than normal for this time of year, so you might not even need the full spring suit.

Honestly, the next couple of weeks are looking pretty quiet. We've got a long stretch of small, weak swell and mostly cross-onshore winds. There's a lot of days where the surf is just not worth paddling out. From Wednesday the 19th of August all the way through to the end of the month, we're looking at small waves, mostly under 3 ft, with a lot of days getting a "poor" call. The energy is weak, with combined swell energy often sitting below 500 (451, 432, 318). That's pretty gutless. The wind is mostly light, but it's coming from the west or southwest, which is onshore or cross-onshore here, so it's chopping up what little swell there is.

There's a bit of a lift in the energy around the 29th of August, with a 4 ft to 4 ft SSW swell and a 17-second period. The combined energy jumps up to 882, which is moderate, and it's a long-period groundswell, which is good for points. But it's still a marginal call, and the wind is still cross-onshore, so it's not going to be clean.

The only real standout in this whole outlook is the very end of the run. On Thursday the 3rd of September, we've got a late afternoon window that looks promising. The swell is 2 ft from the SW, with a 15-second period, giving us a combined energy of 324. The wind is set to go glassy, which is a major positive. That means clean, smooth conditions. For a point break like Terra Mar, which is fairly consistent and exposed to the swell, that could be a fun little session on a longboard. It's a long way out, so don't book the day off work yet, but keep an eye on it.

Everything else is a bit of a write-off. If you're desperate, you could try and make the most of the small, weak days, but it's more of a paddle than a surf. Given the consistent onshore wind and small swell, this setup actually looks more interesting for kite surfing than paddle surfing for most of the period.

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.
