Table - best surf conditions forecast for Terra Mar over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s cooking for Terra Mar over the next couple of weeks.
Honestly, the first week is a bit of a write-off. We’ve got a long stretch of poor surf starting Thursday, July 9, with small, onshore wind and a long-period swell from the SSW that’s just not doing the job. The water temp is about average for the time of year, so no drama there, but the wind is a problem. The first few days through to around July 14 are mostly onshore or cross-onshore breezes, with wave heights scraping around 1 ft to 3 ft. The combined energy is weak, sitting between 195 and 673. It’s a grind. The only real highlight in that first week is the slight window Tuesday morning, July 14, with a glassy SSW swell at 2 ft, but it’s still marginal and the set-up is too weak to get excited about.
Things get interesting around Saturday, July 18. That’s the standout period. We’ve got a jump in swell from the S, hitting 5 ft on Saturday afternoon with a period of 16 seconds, and the combined energy jumps to 2001 – that’s moderate, but it’s the best we’ll see. Wind is light cross-onshore, so it’s not perfect, but it’s workable. The swell direction from the S is a good match for the point break at Terra Mar, which is exposed to that direction. Keep in mind this is a point break, so that long-period groundswell will wrap in nicely. It’s marked as fairly consistent, but crowds are sometimes around, so expect company.
Sunday, July 19, morning pushes up to 6 ft from the S with a period of 13 seconds, but the wind turns onshore from the SW, so it’ll be a bit lumpy. That’s expert territory at that size. The energy drops off after that, and the following week slides back into marginal conditions.
Bottom line: the best chance to get a decent wave is Saturday, July 18, at Terra Mar. It’s not a classic, but it’s the one. The rest of the outlook is pretty quiet, so keep an eye on the forecast.

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.
