Table - best surf conditions forecast for Terra Mar over the next 16 days.
The Lowdown
Alright, let’s talk about Terra Mar. It’s a point break that’s fairly consistent and loves a WSW swell. The water’s sitting at 72°, which is much warmer than normal for this time of year, so you’ll be comfy in a spring suit.
The start of this run is pretty tame. For the first week, the swell is tiny – 2ft to 2ft – with a light cross-onshore breeze. The wave energy is moderate (234 to 406), but it’s all sloppy. You’re looking at poor to marginal conditions with small, weak waves. Not worth the effort. There’s a spike on Wednesday the 26th and Thursday the 27th with swell hitting 4ft to 4ft, and energy climbing over 700, but the period is short (10-13 seconds) and the wind is still cross-onshore. It’s just going to be choppy and messy.
The real window opens on Monday the 1st of September. Swell builds to a solid 4ft, and by Friday the 4th of September we get the best energy of the whole forecast: a strong 1143. The swell is from the SSW, a good angle for this break, and the period is a long 18 seconds. This is the standout. The wind is onshore at 9 mph in the morning on the 4th, so it’ll be a bit lumpy, but the afternoon backs off to a light cross-on at 6 mph, which should smooth things out a touch. This is a serious wave – 4ft of groundswell is for experienced surfers only. And being a point break, those long-period lines will wrap in beautifully.
Saturday the 5th of September still holds that 4ft swell and a light cross-on, though the energy drops to the high 900s. Still a good day, but Friday the 4th afternoon is your best bet. The whole outlook is about average for consistency, so a few flat days in there is normal for the area.

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.
