Alright folks, Rusty here. Let’s take a hard look at what’s ahead for Terra Mar.

Gotta be straight with you – this is a tough run. The overall pattern is a long stretch of marginal to poor conditions, with hardly a window of clean, rideable surf. The swell is hanging around in the 1ft to 4ft range, mostly from the SSW, but the wind is almost constantly cross-on or onshore, which keeps things choppy and messy. The water is a touch warmer than normal for this time of year, sitting at 68°.

The first few days (Sunday 5th through to Wednesday 8th) see a bit of a pulse. Swell heights bump up to about 2ft to 4ft from the SSW, with a long period of 16 to 18 seconds, which is a proper groundswell. The trouble is the wind. Sunday afternoon has a 15 km/h cross-on from the W, giving poor surf. Monday through Wednesday morning, the wind is still cross-on or onshore from the WSW or SW, even though the energy builds to a moderate 899 in the combined energy (moderate wave energy). These are not the clean waves we want. The afternoon of Wednesday 8th is the closest we get to a decent look, with a 4ft SSW swell, a 16-second period, and a light 10 km/h onshore wind from the SW. It’s still marginal, but it’s the best of a bad bunch early on. The combined energy here is 716 (moderate).

After that, from Thursday 9th right through to the end of the 16-day window, it’s a long, grinding slog of poor surf. The swell drops back to 1ft to 3ft, the period shortens, and the wind rarely lets up. There’s a brief moment on the morning of Thursday 16th with a 3ft swell from the W, but it’s a short-period 8-second windswell, and the wind is onshore at 10 km/h. That’s a no-go. The energy drops to a weak 178 for some of the afternoons.

The only standout, if you can call it that, is the afternoon of Wednesday 8th July. It’s the single best option in the whole 16-day run. The swell is 4ft from the SSW, period 16 seconds, and the wind is light onshore at 10 km/h from the SW. It’s a point break, so it can handle that long-period groundswell, and the combined energy of 716 (moderate) is the highest we’ll see with anything close to a clean look. Don’t expect miracles, but it’s the only session worth paddling out for.

For a beginner, those 4ft waves are manageable, but the lack of clean conditions makes it a tough call. There’s a gap of about 10 days from the 9th onwards where it’s really not worth looking at the ocean. The rest of the window is genuinely poor.

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.
