The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking for Terra Mar over the next couple of weeks.
First off, I gotta be straight with you: the start of this run is a bit of a soul session. The first few days are looking marginal, with the swell energy just not there to make it worthwhile. You’ll see a few small pulses but the wind is a pain, either blowing straight on or cross-on, keeping things choppy and messy. The water is way warmer than usual for this time of year, sitting at 74°F with a 7°F anomaly, so you’ll be in boardies for sure, but the surf itself is flat and forgettable.
The first real flicker of hope comes on Wednesday, July 24th. The afternoon sees a slight bump in energy, with the combined swell hitting 1004 (moderate energy) from the SSW at 4ft, but the period is a short 13 seconds. Still, the wind is light and straight onshore, so it’s a bit of a gamble. Honestly, the best bet in this whole stretch is the morning of Saturday, July 26th. That’s when we get a nice 3ft swell from the SW with a clean 21-second groundswell period. The energy is strong at 1097 (moderate), and with light 6 mph SW winds straight onshore, it’ll be glassy and clean. That’s the standout. For a beginner-friendly point break like Terra Mar (point), that long period will make for some nice, lined-up waves, but don’t expect it to be huge. It’s a real treat for a quiet session, though crowds are possible here sometimes.
The waves start to fade out again after that, with the swell dropping and the wind turning cross-on again. By the end of the first week of August, it’s pretty much a ghost town. The morning of Tuesday, August 4th, shows a late pulse of 4ft from the S with a 15-second period and moderate energy (871), but it’s cross-on with a light breeze, so it’s still a marginal call. Nothing to write home about.
So, to sum it up: the clear winner is the early morning of Saturday, July 26th. It’s the only time the stars align for a truly clean, long-period swell. The rest of the window is a mix of small, choppy, or onshore junk. Get out there on that Saturday if you can, because the waiting game after that is long.
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.
