The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer down at Terra Mar. It’s a point break, exposed to a WSW swell, and it’s fairly consistent, but we’re in for a bit of a mixed bag over the next couple of weeks.
The water is sitting at a very warm 75°, which is a whopping 8° warmer than usual for this time of year. That’s a real standout feature – the water is feeling more like a tropical bath than a typical July.
Right now, we’re looking at a bit of a slow start. The first solid window isn’t really until Thursday, July 23rd. The morning has a light SW breeze blowing onshore, with a 4ft swell from the S at 13 seconds. The combined energy is moderate at 642, but it’s only marginal, and the tide might be a bit tricky. It’s a beginner-level wave, so if you’re learning, it’s a window, but it’s not going to be anything special.
Moving into Friday, July 24th, the morning glass-off is a real gem. The wind is light SW and onshore, but the swell is where it gets interesting. We’ve got a tiny 2ft swell from the SW, but the period is a massive 24 seconds. That’s a very long period groundswell. The energy is moderate (869), but that long period means it’ll be super clean, with long, defined lines. For a point break, this is the kind of day where those long, gliding rides are on the menu. The light wind is a major positive. The afternoon drops off a bit with a shorter period.
Saturday, July 25th, and Sunday, July 26th, are similar. The mornings are best with light onshore wind and a 3ft to 3ft swell from the SW, with a period of 19 to 21 seconds. The energy is moderate (945 and 888). Again, that long period is the key here. It’s not big, but it’s clean and lined up. The crowd profile says “sometimes,” so you might have a few others out, but it’s a point break, so there’s room.
The real standout looks like Monday, July 27th, in the morning. We’ve got a 4ft swell from the SW at 18 seconds, with a light SSW breeze blowing onshore. The combined energy is strong at 1055. That’s a solid, powerful groundswell with good shape. The wind is light, so it’ll be clean. For a beginner point, 4ft is a nice size, not too big, not too small. That’s probably the best morning of the first week.
The end of July and into the start of August sees a building swell. On Friday, July 31st, the swell jumps to 6ft to 6ft from the S, with a period of 14 to 15 seconds. The energy is very strong (1279 to 1697). However, the wind is cross-onshore from the W and WNW, making it a bit choppy. At 6ft, it’s getting towards the top end for beginners, and the cross-onshore wind will make it messy. This is more for the experienced guys who can handle a bit of chop.
Then on Saturday, August 1st, we get a 6ft swell from the S at 14 seconds, with a light SW wind onshore in the morning. The energy is very strong (1859). The light wind is a big plus, cleaning up the size. If you’re an intermediate or better, this is a solid day. The afternoon sees a drop in size and a bit of cloud.
After that, the surf fades out. From Sunday, August 2nd, through to Wednesday, August 5th, the swell drops to 2ft to 3ft, with choppy cross-onshore winds and poor conditions. The energy drops to low values (190 to 398). It’s going to be a flat, messy run. There’s a gap of about 4 days with no real surf on offer.
So, to wrap it up: The best bets are the mornings from Friday, July 24th, through Monday, July 28th, for that super clean, long-period groundswell. The absolute standout is the morning of Monday, July 27th, with a strong, clean 4ft swell. The big swell at the end of the month is for the confident crew, but the wind will be a factor.
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.
