The Lowdown

Alright, let’s get into it. Rusty here, and I’ve been staring at the charts for the Terra Mar stretch, and I gotta be straight with you – it’s looking like a bit of a flat spell for the most part. For a point break that likes a good push from the WSW, we just aren’t seeing that magic line-up in the next two weeks. The swell energy is there in numbers, but the quality just ain’t lining up.

The first window we’ve got surf on the cards is from Tuesday, August 25th, but honestly, it’s not much to write home about. Tuesday morning kicks off with a 2ft swell from the SW, but it’s a long-period groundswell at 16 seconds. That’s usually good news for a point break like Terra Mar (Terra-Mar), since those long lines wrap in nicely. But the wind is a cross-on from the WSW at a light 6 mph, so it’s a little bumpy. The combined energy is moderate at 400, but it’s just marginal. The afternoon gets a little bigger at 3ft from the S, but the period drops to 13 seconds, and the wind stays cross-on. It’s a pass.

The swell builds a little into Wednesday the 26th, with 5ft from the S on the morning, but the wind is onshore from the SSW at 9 mph. That’s a bit of a mess. The combined energy hits a moderate 893, but it’s not clean. This is more of a kite-surfing kind of setup for a beach-and-reef point than a proper paddle session.

Thursday the 27th offers a slight glimmer. The swell drops to 4ft from the S, period still at 12 seconds, and the wind swings to a light onshore from the SW at 6 mph. The forecast gives it a bit more love, but the energy is still at 694 (moderate). The waves are there, but the quality’s still marginal. Crowds at Terra Mar can be a thing sometimes, so on a day like this with just okay conditions, it might actually be worth a look if you’re desperate for a paddle.

From late August into September, it’s a slow bleed. By Saturday the 29th, we’ve got a 3ft swell from the SSW with a 17-second period, but the wind is onshore again. The energy is moderate at 687, but the conditions just aren’t clean. The water temp is about average for this time of year, so no surprises there.

The entire first week of September is a write-off. The swell stays small, mostly between 2ft and 4ft, and the wind is almost always cross-on. A few days around the 4th and 5th of September see a little bump back up to 4ft from the SSW with longer periods (16-17 seconds) and lighter breezes, but the cross-on wind still mucks it up. The combined energy around that time is moderate to strong (840-865), but the quality is just not there.

Honestly, the best day on offer might be Saturday, September 5th. The morning has a 4ft swell from the SSW at 16 seconds, with a light cross-on from the WSW at 6 mph. The combined energy is strong at 835. It’s not perfect, but it’s the closest we get to something rideable. If you’re keen, you could snag a few lined-up waves on the point, but it’s a long-range call, so don’t book the day off yet.

That’s the picture, folks. It’s a long stretch of not much, with a couple of barely-there windows. The forecasts can change, so keep an eye out, but right now, it’s the kind of week you take the longboard out for a cruise, not a shred.

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.
