Hey, Rusty here. Let’s talk about Terra Mar for the next couple weeks. I’ll be straight with you—it’s a grim run.
We start off with junk. Waves are running about 3 ft from the SSW, but the wind is a cross-on mess from the WSW and W, blowing at 6 to 9 mph. It’s choppy, bumpy, and just plain ugly. The combined energy is moderate, sitting in the 378 to 474 range, but the quality is zero.
Things start to look slightly less grim on Sunday the 5th, but it’s still only "marginal." The real chance—and I’m using that word loosely—is Tuesday the 7th and Wednesday the 8th. The wind swings offshore from the WSW and SW, dropping to a light 6 mph. The swell comes up to 4 ft from the SSW, with a very long period of 18 seconds. Energy gets strong, hitting 820 to 866. That’s a beautiful-looking groundswell from the data, but the actual reports just say "marginal" with low scores. That 18-second period at a point like this can make the wave a bit too straight, and the swell direction isn’t lining up right with what the spot likes (WSW). So, it’s a gamble—clean looking water with light offshore wind, but the wave shape might not be there.
By Thursday the 9th, the swell drops to 3 ft and the period drops to 16 seconds. The offshore wind holds, but the quality still isn’t clicking. After the 11th, it’s a slow fade. Swell drops under 3 ft, periods shorten to 13-14 seconds, wind goes back cross-on, and energy drops to weak levels below 300. From the 11th through to the 17th it’s basically flat and choppy.
So, my one and only "maybe" spot is Tuesday and Wednesday (July 7 & 8). Clean wind, but questionable waves. For a beginner spot like Terra Mar, 4 ft is manageable. The water is 69°F, which is a touch warmer than normal for July.
It’s a rough outlook, but don’t lose hope. Terra Mar is usually fairly consistent, and forecasts change. This won’t last forever.

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.
