The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks at Terra Mar.
Alright, let’s be real. The first week and a half is a bit of a grind. We’ve got a long stretch of marginal surf, with the first couple of days being pretty lackluster. The water is a crazy 73°F, which is a solid 6°F warmer than usual for this time of year – that’s very unusual, feels like a bath.
The real interest starts to build towards the end of the month. Sunday the 26th of July sees a bit of a pulse, with chest-high 3ft swell from the southwest and a solid 19-second period. That’s a proper groundswell, but with a long period like that, it’s gonna be better on the point. The combined energy is moderate, sitting at 1046, and morning light offshore winds (10 km/h) should keep it clean. The crowd factor is "sometimes" here, so you might have some company.
The stand-out, though, is shaping up for Monday the 27th of July. The swell picks up to 4ft from the southwest, period drops to 18 seconds, but the energy jumps to 1132. Winds are light offshore from the SW at 10 km/h in the morning, promising glassy conditions. That’s the best call on offer. Terra Mar is a point break, and with that long-period SW groundswell hitting it, it should line up nicely. It’s a beginner-friendly spot, but with the swell at 4ft, it’s still manageable for most.
The kicker comes later, though. On Friday the 31st of July, we see a bigger, more powerful swell. The afternoon brings a 7ft S swell with a 16-second period and a massive combined energy of 2088. That’s punchy. The wind is a cross-on 15 km/h from the W, which will put some texture on it. This is expert territory at that size. That same size rolls into Saturday the 1st of August, with a 7ft S swell, but the period drops to 13 seconds, and the energy is still strong at 1324. Morning winds are light offshore, so it could be a good, if heavy, session for the experienced crew.
After that, Sunday the 2nd of August, the energy drops off a cliff. The swell crumbles to 4ft with a short 9-second period, and the wind is messy. It’s a rapid fade-out into the first week of August with very little to recommend.
So, the best of the lot? Monday the 27th of July for the cleanest, most manageable waves. Friday the 31st of July for the big, powerful swell, but that’s for experts only.
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.
