The Lowdown
Alright folks, Rusty here. We’ve got a bit of a flat spell to start, but there’s a serious pulse of swell coming late in the window. Let's break it down.
The first few days are a write-off for any decent surf. We’re looking at small, weak swell with cross-onshore winds, keeping things choppy and messy. The combined energy is weak, so it’s not going to light anyone’s fire. Honestly, for the first week or so, you’d be better off finding something else to do. There’s a gap from now until late in the forecast period before we see anything worth paddling out for.
The real story builds from Thursday, August 27th. The swell starts to ramp up, with a solid S/SSW pulse pushing through. By Friday, August 28th, we’re looking at the standout of the entire forecast. Terra Mar is the place to be. It’s a point break that’s fairly consistent, and it’s exposed to the swell. On Friday afternoon, the wind drops to glassy, calm conditions, and the swell hits 7 ft from the SSW with a period of 13 seconds. The combined energy is strong. This is an excellent session for experienced surfers. The water temp is about average for this time of year. Before that, expect a bit of crowd possible as word gets out.
Saturday, August 29th sees the swell dropping back to 6 ft from the SSW, but the wind turns cross-onshore, so the magic window is really that Friday afternoon session. That’s your one true standout.
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.
