The Lowdown
Alright surfers, Rusty here with a look at what we’ve got on the horizon.
Honestly, it’s a bit of a flat spell we’re looking at. There’s no standout surf on offer, and the models are showing a whole lot of nothing for the first stretch. The juice just isn't there for paddle surfing for a while.
We’ve got about a week of poor surf conditions with cross-onshore winds and weak energy levels. The combined swell energy is barely tickling the 200-400 mark, which is weak. Waist-high dribble and choppy texture is the theme, so if you're itching for a paddle, this isn't the time. The water temp is pretty average for this time of year, nothing wild there.
Things start to look *slightly* less grim around Thursday the 16th of September. We’ve got a little bump from the SSW, maybe knee to waist high. Still, the wind is cross-on, keeping things a bit messy. This is "marginal" at best – think small, workable crumble if you’re desperate.
Moving into the second week, things stay in that same marginal zone. There’s a slight increase in wave energy (pushing into the 500-600 range by the 21st of September) with a cleaner SW swell coming in. The tide and wind will still mess with it, but the period picks up to a nice 17-19 feet per second in real terms. That’s a proper groundswell, so there’ll be more energy per wave, but those long gaps between sets will be the trade-off. Winds are mostly light, so it’ll be less choppy, and you might get a sessionable waist-to-chest high wave if you’re patient and pick your tide.
The only spot in the game is Terra Mar. This is a point break, so it’ll handle that long-period SW groundswell better than a beach break. It’s fairly consistent, but the optimum direction for it is WSW, and we’re getting a lot of SW. The best call is probably on Saturday the 19th of September afternoon, when the swell is 3 ft at 18 seconds from the SW, and the wind is light and cross-on. It's a beginner-friendly spot, so the size isn't threatening. The crowd factor is listed as "sometimes," so you might have a few locals out.
For the rest of the window, it’s pretty lifeless. A blank run like this is just the way it goes sometimes. Forecasts change, but right now, don't hold your breath.
Rusty.

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.
