The Lowdown

Alright folks, Rusty here. Let’s get into it. We’re looking at Terra Mar, and honestly, the next 16 days are a bit of a grind. We’ve got a long stretch of small, messy, and marginal surf ahead, with only a couple of moments that might get the heart rate up.

The first real shout comes in on Sunday, September 6th. The swell ticks up to 6ft to 6ft from the S, with a period of 14 seconds. That’s a solid, moderate groundswell hitting the beach, with combined wave energy jumping up to 1320 and 1413 – that’s a noticeable push. Winds are light and onshore, so it won’t be glassy, but it’s the biggest we’ll see. The water temp is about average for this time of year. This swell carries into Monday, September 7th, with similar 6ft to 7ft SSW swell, but the wind swings cross-on and picks up to 12 mph by the afternoon, making it choppy. It’s a bit too big for beginners at 6ft, and the texture won’t be perfect.

The standout window, if you can call it that, is really that Sunday morning. It’s the most size and energy we get, even if the wind isn’t ideal. The rest of the first week drops off fast. Tuesday and Wednesday see the swell fading back to 3ft to 5ft, with light cross-onshore winds and poor to marginal conditions. The wave energy drops from 1116 down to 547, so the power is gone.

Then we hit a real flat spell. From Thursday, September 10th, all the way through to the end of the forecast window on September 18th, we’re stuck with tiny, weak swell. Heights are mostly 1ft to 2ft, with periods all over the shop. The combined energy is mostly under 500, with some days dipping below 200. That’s weak. There’s a weird, long-period 22-second pulse on Thursday, September 17th, but it’s only 2ft, so it’s all show and no go. Wind is a constant cross-on from the west, making it choppy and rubbish. Not a single day in that second week offers anything worth paddling for.

Bottom line: The best of a bad bunch is the morning of Sunday, September 6th. It’s not a classic, but it’s the only time the swell has enough size to make you look twice. For the rest, keep the board in the car and the expectations low.

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.
