The Lowdown
Right then, let's have a look at what's on offer for Terra Mar over the next couple of weeks.
The water's running at a very unusual 75°, which is much warmer than normal for this time of year – a nice surprise.
Honestly, the outlook is a bit of a mixed bag. There's a pulse of solid long-period groundswell coming in, but the wind is mostly going to be a problem, keeping things messy. For a point break like this, that longer-period swell (over 15 seconds) is good news for shape, but it's going to be a battle to get a clean one.
The first real chance of something rideable is the morning of Sunday the 6th. We've got some solid 6ft swell from the S, with a period of 14 seconds, and the wind goes light cross-offshore, making things clean. The combined energy is strong at 1332. It's not perfect, but it's the best the weekend has to offer and the closest thing to a standout in this whole run.
Monday the 7th sees the swell build further to 7ft and then 7ft, but the wind goes cross-onshore and choppy, especially by the afternoon when it gets ugly. That's really only for the more experienced crew if they can link up with a clean window, but the conditions are poor. By Tuesday the 8th, the swell starts to drop and the cross-onshore wind is back, so it's back to being marginal.
From Wednesday the 9th onwards, the swell drops right off. We're looking at a long stretch of poor conditions with small, weak swell. There's a gap of several days where there's really nothing to get excited about, with heights dropping below 3ft. The energy values dip down into the hundreds, which is weak.
Looking way ahead to the 18th and 19th, there's a whisper of a new, long-period SW groundswell (20 seconds) arriving, with about 3ft of swell. The wind looks light, so it could be a last roll of the dice for the more patient surfer, but it's a long way out and not something to bank on. Given the constant cross-onshore wind, a kite would have a much better time here than a paddle board for most of this period.

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.
