The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for Terra Mar over the next couple of weeks.

Straight up, it's a slow start. The first decent surf we see won't be until Sunday the 6th. Up until then, the waves are small and the wind is messy, so keep your board on the roof for now.

Sunday the 6th is our first chance. The swell builds to a solid 6ft from the South, with a period of 14 seconds, pushing a good amount of energy through (1446). The wind swings offshore from the North, cleaning things right up. This is the standout morning of the whole outlook. Terra Mar is a point break, and this long period S swell will wrap in nicely. The wave energy is moderate to strong, and with that offshore breeze, you're looking at clean, peelable lines. The water temperature is a very unusual 75°, which is much warmer than normal for this time of year.

The surf holds into the afternoon too, unchanged at 6ft from the S, with a bit less period (13 seconds). Offshore wind from the NNE keeps it clean.

After that, it turns messy again. Monday the 7th sees the swell jump to 7-7ft from the SSW, but the wind swings cross-onshore and gets choppy. The energy is there (over 1500), but the quality drops right off. This setup is better for kite surfing than paddling.

From Tuesday the 8th through the 16th, it's a downhill slide. The waves shrink back down below 3ft and the wind is mostly cross or cross-onshore from the West or WNW. There's a short window on the morning of Thursday the 10th with clean offshore wind from the SSW and a 3ft SW swell with a very long 17-second period, but the overall score is still weak – it'll be small and the long period will make it fat on a beach break but at Terra Mar point it might offer a few.

The second week, from around the 11th onward, is bleak. Consistent small waves under 3ft, poor to marginal conditions, and mostly onshore winds. The energy dips into the low hundreds, and by the 17th it's barely registering over 300. The last few days, the 18th and 19th, see a tiny lift back up to 3ft from the SW with a long period (18-20 seconds), but the wind is still cross-onshore, so don't get too excited.

So the call is simple: if you want the best of it, be at Terra Mar on Sunday the 6th. That’s the cleanest, most consistent window of the whole 16 days.

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.
