The Lowdown
Alright folks, Rusty here with a look at the upcoming surf at Terra Mar. It's a bit of a tough stretch ahead, so let's keep it real.
Straight up, the next 16 days are looking pretty flat. We've got a long gap of nothing but small, messy, and poor surf conditions. The water temperature is sitting at a very unusual 75°, which is a solid 7° warmer than normal for this time of year – feels like a bath out there.
The first real chance of anything rideable doesn't show up until Friday morning, August 14th, and even then it's only marginal. From August 11th right through to the morning of August 14th, it's all poor surf with tiny waves, cross-onshore winds, and a lot of chop. The energy is weak, with values barely climbing into the low hundreds. For example, early on the 11th, the combined energy is only 222 (moderate) but the swell is a weak 2 ft from the SSW at a short 13 seconds.
The most promising period, if you can call it that, is from Saturday morning, August 15th, through to Monday morning, August 17th. The swell bumps up just a touch, with the best of it being Saturday afternoon, August 15th, with a 4 ft swell from the SSW at 16 seconds, and combined energy hitting 718 (moderate). But the wind is still a cross-onshore breeze, so it's going to be a bit choppy. It's a marginal call at best, and the spot is a beginner-friendly point break that's fairly consistent, but the conditions are just not cooperating.
After that, from the 17th onwards, it's back to tiny, poor surf with weak energy readings dropping back into the 100-300 range. The swell direction stays mostly SSW to SW, which is nearly optimal for this spot, but the size just isn't there. For a stretch from August 18th through to the 26th, it's a parade of clear skies and poor surf, with the occasional marginal window, like the Tuesday afternoon, August 25th, where the score manages a 1 out of 10.
Honestly, there's nothing here that gets me excited. The wind is almost always cross-onshore or onshore, the waves are small, and the quality is poor. With the size being so small and the conditions so choppy, this setup looks more interesting for a kite session than a proper paddle surf. Sometimes you just have to wait for the next forecast to turn things around.

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.
