The Lowdown
Alright folks, Rusty here. Let’s get into it. We’re looking at a slow start, but there’s a window of proper surf coming. The water is sitting at 77°, which is a full 9° warmer than usual for this time of year – that’s seriously unusual, so you’ll be in boardies for sure.
The first few days are a write-off. From Tuesday the 1st right through to Friday the 4th, it’s all poor surf conditions at Terra Mar. The swell is small, between 2ft and 3ft, and the wind is a messy cross-onshore. The wave energy is weak to moderate (242 to 821), and the reports are all “poor.” Not worth paddling out.
Saturday the 5th shows a slight pulse. The morning is still marginal with 3ft SSW swell, but the energy is building (991). By Saturday afternoon, we see the swell bump to 4ft from the S at 14 seconds, and the energy jumps to 1234. Still only marginal, but it’s a sign of life.
Now, Sunday the 6th is where it gets interesting. Sunday morning brings 6ft S swell at 14 seconds, with solid energy (1528). The wind is light cross-onshore, so it’s still a bit lumpy. But Sunday afternoon is the standout. The wind shifts to a light 6 mph cross-offshore from the North, cleaning things right up. The swell hits 7ft from the S, period 14 seconds, and the energy is pumping at 1980. The report says “excellent surf conditions for experienced surfers.” That’s your window. This wave is over 8ft? No, it’s 7ft, so it’s solid but not expert-only. It’s a big, clean swell for anyone who’s comfortable. The direction is SSW, which matches the optimum for this exposed point break. Crowds are "sometimes" here, so you might have company.
Monday the 7th is the biggest but the wind gets messy. The morning has 8ft S swell with a massive energy reading of 3127, but it’s a cross-shore WNW breeze at 9 mph, creating some chop. The afternoon is worse – 19 mph NW wind turning it lumpy. This one is for the pros only, and even then, it’s not clean.
From Tuesday the 8th onward, the swell fades fast. By Tuesday the 8th, it drops to 6ft, and the wind is back onshore and choppy. Wednesday the 9th through the end of the 16-day period (September 16th) is a long stretch of poor conditions. The swell drops to 1ft to 3ft, energy is weak (under 600), and the wind is consistently cross-onshore. There’s a brief moment on Saturday the 12th morning with a light onshore and 3ft, but it’s marginal at best. After that, the surf is gone.
The pick of the entire run is Sunday afternoon, September 6th. Clean 7ft S swell, light offshore wind, and a point break that likes this direction. It’s the only real standout.
Rusty out.

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.
