The Lowdown
Alright folks, Rusty here. Let’s break down what’s on the cards for Terra Mar over the next couple of weeks.
It’s pretty quiet out there, to be honest. We’re looking at a long stretch of small, weak surf that’s mostly going to be a struggle. The real standout, if you can call it that, is right at the start.
Wednesday, July 29th is your best bet. We’ve got a clean, clear morning with a light breeze blowing from the SW at 6 mph. The swell is a modest 4 ft coming from the SSW, with a nice long period of 16 seconds. That’s proper groundswell energy, and with the light offshore wind, it should be pretty clean. The water’s sitting at 75°, which is a massive 8° warmer than usual for this time of year – that’s really unusual, you won’t feel the chill. The combined energy is moderate (870), so it’s not a powerhouse, but for a point break with a WSW optimum, this is your window. It’s a beginner-friendly spot, fairly consistent, but expect crowds *sometimes*.
Come Wednesday afternoon, the wind swings cross-on and the quality drops. The surf then slowly fades through Thursday and into Friday. By Friday morning, the breeze picks up to 9 mph and it’s turning choppy. The swell is still around 4 ft but the period shortens and the energy is weakening (655). It’s marginal at best.
From Saturday, August 1st right through to the end of the second week, the story is all the same: poor surf conditions. The swell drops below 3 ft, the energy is weak (three-digit values in the low 100s to 300s), and the wind is either on or cross-on. There’s a brief tease on Friday, August 7th with a very long period of 19 seconds, but the swell is tiny at 1 ft and the energy is still low (228). It’s just not enough to push through. The setup looks more interesting for kite surfing than paddle surfing with that constant cross-on breeze.
So, honestly, there’s a big gap of pretty much nothing from the end of July through to August 13th. If you’re desperate, the Wednesday morning window is the only one worth a look. The long-range stuff in the second week is promising on paper with the long periods, but the size just isn’t there. Forecasts can change, but right now, it’s a waiting game.
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.
