Alright folks, Rusty here. Let’s break down what Terra Mar is serving up for the next couple of weeks. Gotta level with you – it’s not going to be a clean run. Most of the time we’re fighting a cross-onshore wind which is chewing up the surface. The water is a balmy 71°F, which is a solid 4°F warmer than normal for this time of year – feels like a warm bath out there.
The first real recommendation doesn’t show up until Tuesday, the 22nd of July. Before that, from this Sunday the 12th all the way through the 21st, you’re looking at a long dry spell with mostly weak energy (combined energy between 180 and 924) trapped under poor conditions. Not worth suiting up.
On Tuesday, the 22nd of July, things perk up at Terra Mar. We’ve got a SSW swell at 3ft with a 15 second period. That long period brings real power, but at a beach break it can make the waves stand up too straight for a smooth drop. The wind is light from the SSW, going from glassy in the morning to a light cross-onshore in the afternoon. Combined energy jumps to 1306 – a solid step up and the best option early in the forecast.
The real standout is Thursday the 23rd. Thursday morning brings the biggest swell of the whole window: 7ft from the S with a 14 second period. That’s expert territory, too much for beginners. A light cross-onshore stays on it, but combined energy hits a powerful 1647. Friday the 24th follows up with 6ft from the SSW at 13 seconds (energy 1443), though that wind stiffens a bit. If you’ve got the skills, Thursday morning is your golden hour. Big, solid lines, but expect a crowd – Terra Mar can get a sometimes pack when there’s real size.
After that buzz, the swell fades. By Saturday the 25th it’s dropping fast, and into the final week we’re back to small, long-period dribble. Sunday the 26th gives you 2ft from the SW at a very long 20 seconds – lots of motion in the water but not much to ride.
If you’re planning a session, lock in the 22nd through the 24th. Not perfect, but it’s your best chance at a wave.

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.
