The Lowdown

G'day, it's Rusty here. Well, I've gotta be straight with you – the next couple of weeks are looking pretty average for Terra Mar. It's a point break that's exposed to the swell, but the conditions are just not playing ball. We've got a long stretch of onshore and cross-onshore winds that are going to mess with the surface, and the swell is mostly small and weak. The water temp is a wild 75° and that's a massive 7° warmer than usual for this time of year, which is very unusual.

Let's walk through it. Friday, August 28th, is the best of a pretty ordinary bunch. The morning offers a clean 3ft SSW groundswell with a long 17-second period, and a light offshore breeze. The combined energy is only moderate at 515. It's a beginner-friendly break, but it's inconsistent, so don't expect a wave every minute. The afternoon stays clean but the swell drops to 2ft.

Saturday, August 29th, starts with a clean 4ft SSW swell, but the score is a zero. The wind is offshore but the surf is just poor. The afternoon turns cross-onshore, so it's not great.

From Sunday, August 30th, right through to Monday, September 7th, it's a real drag. The wind is mostly cross-onshore or onshore, the swell is tiny (2ft to 4ft), and the energy is weak to moderate. The combined energy drops as low as 247 on September 1st. It's a long stretch of messy, choppy, and poor surf. There's a small uptick in swell on Thursday, September 3rd, with 4ft SSW swell and 15-second period, and the morning is clean, but the afternoon is cross-onshore, so it's marginal.

The second week doesn't really get any better. From September 8th to 10th, it's more of the same: small, cross-onshore, poor surf. The swell period gets long again on the 8th (18 seconds) and 10th (17 seconds), but the size is tiny at 2ft and 2ft.

Then, on Friday, September 11th, we get a bit of a pulse. The swell jumps to 5ft from the S with a 14-second period, and the combined energy hits 1042 in the afternoon, which is strong. The wind is cross-onshore though, so it's still messy. Saturday, September 12th, has 5ft S swell in the morning and 3ft SSW in the afternoon, but again, cross-onshore wind. This is getting into the size where beginners might struggle, but it's not a clean wave.

Honestly, there's no standout day here. The best chance for a clean wave is Friday, August 28th, with that light offshore wind and 3ft groundswell. It's small and inconsistent, but it's the cleanest. The bigger pulses later on are ruined by the wind.

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.
