The Lowdown

Alright folks, Rusty here. Let's take a long, hard look at what's on offer for Terra Mar. I gotta be straight with you—this is going to be a tough stretch. The swell is small and the wind is working against us for most of it, so we're really waiting for the very end of the window to see anything even close to worthwhile.

For the first nine days, from the morning of Wednesday, August 5th right through to the afternoon of Wednesday, August 12th, it's pretty grim. We're looking at tiny waves, mostly around 2 to 3 feet, and the wind is stuck in a cross-on or onshore pattern from the west-southwest. The combined energy is weak to moderate, sitting between 141 and 466, but the quality is shot. It's all labelled as "poor surf conditions." There's nothing to get excited about here.

Things start to look a little different on the morning of Thursday, August 13th. The swell picks up just a touch to 3 feet, still from the south-southwest, but we start seeing a bit more energy, hitting the 466 mark. Still, the wind is cross-on, so it's not clean.

But the real turnaround, and the only standout in this whole 16-day run, happens on Friday, August 14th. The swell stays around 2 to 3 feet from the south-southwest, but the period stretches out to a solid 19 seconds. That's a long-period groundswell, meaning proper energy and shape, but watch out—it might break a bit straight at a beach break. The combined energy jumps to a strong 627. More importantly, the wind goes light and variable, shifting to cross-on from the west. The notes say "marginal surf forecast or questionable tide conditions," but this is the best we've got. It’s a 1 out of 10 on the score, but in this context, that's the winner.

However, that little window doesn't last. By Saturday morning, August 15th, we're back to cross-on winds again and the quality drops right back to "poor." The swell does build a bit more, hitting 4 feet on the Saturday afternoon, but with that cross-on breeze, it's messy. That bigger swell with a bit of punch is only really going to appeal to the more experienced lot, but the wind spoils it.

The water is sitting at a very warm 77°F, which is a massive 9° warmer than the norm for this time of year. That's genuinely unusual—like swimming in bath water.

So, if you're hanging for a wave, your best bet is to pencil in Friday, August 14th. Early morning looks the pick for that longer-period groundswell and lighter winds. But honestly, the whole period is a struggle. Don't hold your breath.

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.
