The Lowdown
Alright, let’s break it down for Terra Mar. The outlook here is pretty bleak for the next 16 days. Swell energy runs from moderate to strong, reading between 223 and 717, but the quality just isn't cooperating.
The water temperature is running at 76°, which is about 8° warmer than the norm for this time of year. That’s a really big difference.
Sunday the 9th kicks off with an afternoon session: a 3 ft swell from the SSW with a 15-second period (a nice long groundswell) and moderate energy (352). The wind is onshore from the WSW at 9 mph, making it a poor session. Score is a 0. It’s a rough start. From Monday the 10th through Thursday the 13th, it’s all similar: small swells ranging 2 ft to 2 ft, with onshore or cross-onshore winds and scores of zero.
Friday the 14th morning gives a tiny bit of hope. A 2 ft SSW swell with an 18-second period, energy at 554 (moderate-strong). Wind is cross-onshore from the W at 9 mph. The report says "marginal surf forecast or questionable tide conditions" with a score of 1/10. Still not good, but it’s the first time we’re seeing a 1.
The best option comes on Saturday the 15th. The morning has a 3 ft SSW swell, 16-second period, with moderate-strong energy (653) and an onshore wind from the WSW at 9 mph. The afternoon is slightly better: a 4 ft SSW swell, 16-second period, stronger energy at 743. The wind drops to a light breeze from the WSW at 6 mph, but it stays cross-onshore. It’s still a marginal session, scoring a 1/10, but that afternoon window has the lightest wind you’ll see.
From Sunday the 16th onward, it’s all downhill again. Swells shrink to 1 ft to 3 ft, and the winds stay cross-onshore or onshore. The second week, from the 17th to the 24th, is a total loss. The morning of the 19th brings a 3 ft SSW swell, but the wind is onshore at 9 mph, and it’s a zero score.
This is a point break that’s fairly consistent, but the conditions are just wrong for it. There’s no standout session here. If you have to paddle out, go for the Saturday the 15th afternoon for a tiny window of light wind and the biggest swell, but it’s a real long shot. For beginners, the size is manageable but the onshore winds and tide issues will make it tricky. Honestly, with the persistent cross and onshore winds, this spot looks more like a kite surfing venue than a paddler's paradise.
Don’t get your hopes up.

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.
