Table - best surf conditions forecast for Terra Mar over the next 16 days.
Alright, Rusty here. Let’s talk about what’s coming up for Terra Mar.
Honestly, it’s a slow start. From Friday, July 10th, we’re looking at a pretty long stretch of nothing much. The water is sitting at about 70°, which is a touch warmer than normal for this time of year, but that’s about the only thing going for us. For the first week or so, there’s consistent swell from the SSW around 3ft, but the wind is all wrong – mostly onshore or cross-onshore, chopping everything up. The wave energy is moderate, around that 475 mark, but it’s just not clean. No dice.
That run of poor conditions goes right through the middle of the month. We see tiny pulses of swell dropping to 1ft with long periods up to 18 seconds, but it’s just too small and the wind is still a problem. There’s a little window on Monday, July 20th, with the energy picking up to 614, 3ft of SSW swell and light offshore wind from the SW. That could give you a clean, small wave, but it’s marginal quality at best.
The one that jumps out is Saturday, July 25th – but that’s over a week away, so don’t get too excited yet. The numbers get interesting: swell height jumps to 6ft to 6ft from the south with a 15 to 16 second period. The combined energy goes strong, up to 1490. The wind on Saturday morning is cross-onshore, but the forecast shows it turning light offshore in the afternoon. 6ft of south swell with clean wind? That’s the only real standout in the whole outlook. Just remember, Terra Mar is a point break that works best with a WSW swell, so this south direction is a bit off.
So it’s a long dry spell with one promising but uncertain highlight at the end. For a spot like this, patience is the name of the game – things can change quick.
Rusty, signing off.

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.
