The Lowdown

Alright, let’s get into it. The next couple of weeks are looking pretty grim for a proper surf, if I’m being honest. We’ve got a window that starts now, but the waves are small, and the wind is doing us no favors. Don’t get too worked up about the first few days – it’s gonna be a waiting game.

The surf window kicks off on Saturday, August 15th. We’ve got some chest-high lines at Terra Mar (Terra-Mar) with a swell out of the SSW at about 4ft and a long 16-second period. But the wind is cross-onshore, and it’s choppy. The water is a warm 74° – that’s way warmer than usual for this time of year, which is a bit wild. The energy is weak, so it’s not really doing much. This is a marginal call, not something you’d rush out for.

Sunday the 16th stays small at 3ft. The morning is better, with a light cross-on breeze but still a bit of ripple on it. The afternoon is worse with a moderate cross-onshore wind and chop. It’s just not clean.

From Monday the 17th through the following week, it’s mostly poor. We see the swell dropping: about 3ft on Monday, down to 2ft by Tuesday, and it just stays weak and wonky. The wind does swing around to onshore, but the size is too small to get any real power. The combined swell energy is weak. This is a stretch with no real highlights – a solid gap of about seven days where you’re not going to find much.

Around the 23rd, we get a bit of a pulse with a 1ft swell but a long 19-second period, but it’s tiny. The wind is still light and cross-onshore, and it's just a blip. Not worth the paddle.

The second week stays pretty flat, with the occasional 2ft bump but nothing that breaks the surface tension. This is a period for tinkering with your gear, not for getting wet.

Now, here’s the standout. All eyes on Friday, August 28th. That afternoon, the swell starts to fill in at about 4ft from the SSW with a 16-second period, and the energy is the most promising we’ve seen in the whole period. The wind is light cross-onshore, so it should clean up. It’s not huge, but it’s the best we’ve got. Saturday the 29th morning also holds at about 4ft with a longer 18-second period. That’s your window.

The caveat here is that this is a point break, and with that long-period southwest swell, it should wrap in nicely. But with the long period, keep in mind it can get a little straight at a beach break, but at a point, it should be fun. It’s still a bit soft, but it’s the only time with any real push. This is the one to try to make.

So, overall, a long, slow grind ahead, but the last Friday into Saturday looks like the only real chance for a few proper waves. Don't hold your breath for anything between now and then.

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.
