The Lowdown

Right then, let’s have a look at what’s on offer for the next couple of weeks. I’ll be straight with you – it’s been a tough stretch. The first proper surf I can see kicks off on Monday the 10th of August, but honestly, it’s nothing to write home about. We’re looking at a small, weak SSW swell at Terra Mar, peaking at about 3 ft, with a period of 14 seconds. The water is a balmy 76° – that’s a whopping 8° warmer than usual for this time of year, which is very unusual, but it’s not enough to save the day. The wind is onshore from the WSW at 9 mph, and the combined swell energy is a paltry 319. It’s poor surf, no other way to say it.

The whole first week is a bit of a write-off, to be honest. The wind is nearly always on or cross-onshore, mostly from the west or southwest. The swell stays small, between 2 ft and 3 ft, and while the combined energy does climb a bit – hitting 680 on the 14th for example – the conditions are never clean. It’s choppy and poor. Even the “marginal” labels on the 13th and 15th are just a kinder way of saying it’s not great.

There’s a single moment that stands out, and it’s a long way off. On Monday the 24th of August, in the afternoon, we get a real treat. The wind swings around to a light NW at just 3 mph, turning cross-offshore. The swell is still small at 2 ft from the SW, with a period of 17 seconds, and the combined energy is 269. But that clean, glassy wind? That’s the key. It’s the only time in the whole window the forecast says “expect good surf conditions.” For a point break like Terra Mar, which is a beginner-friendly spot that’s fairly consistent, this is the one to aim for. The swell direction is SSW, which is a little off the optimum WSW, but with that kind of wind, you’ll take it.

After that, it’s back to a poor run of cross-onshore winds and tiny swell through to the end of the outlook. The combined energy drops right down to 129 and 186 on the 22nd, so the energy is truly weak.

So, the short story is: there’s nothing on the table for the next week or so. But don’t despair. The 24th of August offers a genuine window of clean, small waves at Terra Mar. Mark it in your calendar. It’s a long way out, so keep an eye on it, but that’s the best bet we’ve got.

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.
