The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Terra Mar.

First thing you’ll notice is the water. It’s sitting at 72°, which is a whopping 6° warmer than usual for this time of year. That’s proper tropical-feeling bathwater, very unusual, so you might not even need a spring suit.

Now, the surf. Honestly, it’s a pretty flat and quiet run for the next week and a half. The first few days from Thursday the 16th through Sunday the 20th are mostly a write-off for anything decent. We’ve got tiny, weak swell with a combined energy that’s barely nudging past 200 (weak) and the wind is cross-on or onshore, just making a mess of things. The morning of Saturday the 18th sees a bump to 3 ft, but it’s still marginal.

The real standout window starts to show up on Sunday the 19th. That morning we get a jump to 5 ft from the S, with a period of 13 seconds and a solid energy reading of 1308 (strong). The wind goes light and onshore, so it won’t be glassy, but it’s a big improvement. The afternoon picks up to 6 ft, which is getting solid for a point break like Terra Mar. That’s pushing into expert territory, especially for the bigger sets. The direction is SSW, which isn’t its optimum WSW, but the size makes up for it.

Monday the 20th keeps the fun rolling with 5 ft in the morning from the SSW, period 14 seconds, and light onshore winds. The energy is still strong at 1030. This is the best bet for the whole outlook. It’s not perfect, but it’s the most size we’ll see with the cleanest conditions. The afternoon does drop off a touch.

The second week gets a bit more inconsistent. Monday the 27th has a decent morning with 4 ft from the SW, period 18 seconds, and a light cross-on breeze. That’s a long period, so it’ll have some punch, but it might be a little straight at the beach. The afternoon of the 27th is actually the last decent call with 4 ft and a 19-second period, and energy at 1282. It’s still a cross-on wind, but it’s rideable. Tuesday the 28th afternoon sees a similar size but with a more onshore wind, so it’s a toss-up.

Honestly, the pick of the whole 16 days is the morning of Sunday the 19th and the morning of Monday the 20th. That’s where the swell and the wind line up best. The rest is a lot of waiting.

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.
