The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the table for the next couple of weeks at Terra Mar.
It’s a quiet start. We’ve got a long stretch of "marginal" conditions before things get interesting. From Thursday the 23rd to Friday the 31st of July, the swell is just hanging around 2 ft to 5 ft, but the wind is mostly cross-on or onshore. The water is running a wild 75° – that’s much warmer than normal for this time of year, so you can leave the wetsuit at home. The wave energy sits in the moderate range (between 581 and 975), but the quality just isn’t there yet. The period is all over the place, with a very long 24-second groundswell on Friday the 24th, but that’s locked into a south-southwest swell with onshore wind, so it’s messy.
The real standout window kicks off on Monday the 27th of July. The morning sees a clean 4 ft swell from the south-southwest, period 18 seconds, and the wind turns light and offshore. That’s a game-changer. The combined energy jumps to 1106 (strong), and the break is a fairly consistent point. This is the best on offer. Monday afternoon stays clean with 4 ft and offshore light breeze. Tuesday the 28th of July is even better: 5 ft from the south-southwest, a 17-second period, and light offshore wind all day. Energy is 1156 (strong). This is the pick of the week. The swell direction (SSW) is a good match for the optimum (WSW) – not perfect, but close enough for a point break. Crowds are possible here, so get there early.
After Tuesday, the quality drops again. By Friday the 31st of July, the afternoon swell bumps up to 5 ft from the south, but the wind swings cross-on and the energy is strong (1173), but the wind messes it up. Saturday the 1st of August looks promising on paper with 6 ft from the south and a 13-second period, offshore wind, and strong energy (1307), but that’s a short period swell and the size is pushing into “not for beginners” territory. It’s a point break, so it might hold shape, but it’s a gamble.
Then from Sunday the 2nd of August onward, it’s all poor conditions. Swell drops to 4 ft, then 1 ft, with weak energy (under 500) and choppy cross-onshore winds. The forecast dries up completely for about a week, from the 2nd to the 7th of August. This is a normal blank run for the area when the wind isn’t playing ball.
Best bet: Monday the 27th and Tuesday the 28th of July. Clean, offshore, 4 ft to 5 ft south-southwest swell with good energy. Get on it.
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.
