The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Terra Mar over the next couple of weeks.

Right off the bat, I gotta be straight with you – the outlook is pretty grim. We’re in for a long stretch of poor to marginal conditions that drags on for days. It’s not looking great for a proper paddle. The first real hope doesn’t show up until Monday the 7th of September, and even then, it’s got its own problems.

The first few days, from Sunday the 30th of August right through to the end of the first week in September, are a write-off. We’re looking at small, weak swell with a combined energy of just 162 to 629 (moderate wave energy at best), and the wind is mostly cross-onshore, which is chopping everything up. You’ll see a bit of long-period groundswell (periods from 14 to 18 seconds) on the 3rd and 4th of September, but the clean, light wind just isn’t there to make it work. The water temperature is a very unusual 77°F, which is far warmer than normal for this time of year – a real anomaly.

Then, into the second week, things get a bit more interesting, but it’s not for the faint-hearted. The weekend of the 6th and 7th of September sees a solid bump in size. On Sunday the 6th, we’ve got 6 ft of S swell (14-second period) with a combined energy of 1212 (strong wave energy), but the wind is a strong cross-shore and cross-onshore, making it a messy, choppy beast. That’s more of a kite session, honestly.

The standout of the whole period, and the only one really worth circling on the calendar, is Monday morning, the 7th of September. We’ve got 6 ft of SSW groundswell (14-second period) with a strong combined energy of 1290 (strong wave energy). The wind is light and blowing *on* from the SSW, which is the optimum direction for this spot. This will give Terra Mar point some clean, lined-up waves. The size is manageable for most, but at 6 ft, beginners might find it a bit too much. The long period means the sets will be powerful and well-spaced, which is a dream for a point break. Yeah, it’s a mid-sized swell, but with that glassy wind, it’s your best bet.

After that, Tuesday the 8th of September gets big – 8 ft to 12 ft of SSW swell – but the wind is cross-onshore again, and the energy is through the roof (4036 – very strong wave energy). That’s big, angry, and choppy water. Only for experts, and even then, it’s not going to be pretty. The rest of the second week fades back into small, weak, and onshore mush.

So, here’s the bottom line: this is a tough forecast. A long, dry spell followed by one promising morning. Keep an eye on that Monday the 7th of September for the best chance of a glassy, punchy session at Terra Mar.

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.
