The Lowdown
Hey, it’s Rusty. Let’s run through Terra Mar over the next couple weeks. The water’s sitting at 73°F, which is nearly 5°F above normal—pretty wild for this season.
The first real chance comes on Wednesday, September 2nd in the morning. Wind’s flat glass, and the swell’s 4ft from the SSW, combined energy moderate (591). It’s clean, small, but you can have fun.
The standout is Thursday, September 3rd afternoon. Swell steps up to 6ft from the SSW, with a light cross-off breeze and clean faces. Wave energy is strong (1008). That period is around 12 seconds, so you’re getting proper lines. 6ft is big enough that beginners should sit it out—this is for experienced crew only.
Other spots? Tuesday, September 8th afternoon is worth a look. Glassy wind, but only 2ft of swell from the SSW with a ridiculously long 18-second period. It’ll be clean and smooth, but you’ll need a log or a foil to make the most of it.
Most days have wind on it or choppy conditions. Crowds pop up “sometimes” on the better days.
Bottom line: Mark your calendar for Thursday, September 3rd afternoon. That’s the one.

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.
