The Lowdown

Alright folks, Rusty here. Let’s get into it for Terra Mar.

Honestly, the next week and a half is a tough one for paddle surfing. The pattern is dominated by a persistent cross-onshore or onshore wind from the WSW to SW, and the swell is just not cooperating. We’re looking at a long stretch of poor surf conditions, with the combined swell energy ranging from moderate (222) to pretty strong (712), but the quality is just gutted by the wind. Most of the time, the waves are in the 2 ft to 4 ft range from the SSW or SW, with a period that’s mostly in the 13-18 second range. Even though that’s a nice groundswell period, the wind is ruining it for us.

The first real standout doesn’t come until Thursday, 20th August. It’s the one bright spot in the whole 16-day window. *Terra Mar* is a point break, and it’s fairly consistent. It’s exposed to the swell, and the optimum direction is from the WSW which matches the swells. On the morning of the 20th, it’s still cross-onshore and messy, but then in the afternoon, the wind goes glassy. Total calm. The swell is a small 3 ft from the SSW, but with that glassy surface, it’s going to be clean and fun. The combined energy is moderate at 312, so it’s not powerful, but it’s workable. Because it’s a point break, that long-period groundswell (14 seconds) will wrap in nicely. This is the best on offer, no question. It’s a small day, but clean.

The Saturday before, 15th August, has a couple of marginal sessions. The morning is cross-onshore with 3 ft at 16 seconds, and the combined energy is 648. The wind is light, but it’s still cross-onshore. The afternoon gets a little better with a cross-shore wind and a slightly bigger 4 ft, 16-second swell from the SSW. The combined energy hits 712. It’s still a marginal call, but it’s the most size you’ll see in the whole period. The cross-shore wind is better than the usual cross-onshore, so it might be worth a look if you’re desperate, but it’s not a standout.

After that 20th, it fades. The last week of the forecast into late August is mostly poor again, with small waves and wind messing things up. The water temperature is about average for the time of year.

The long gap here is real. You’re looking at a solid 10 days of mostly poor conditions, from the 10th right through to the 20th, with only a few marginal windows. The 20th is the one day to circle. For beginners, the swell is small enough to be safe, but the quality is so low most days it’s not worth the paddle. The 20th afternoon is the exception.

Rusty out.

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.
