The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Terra Mar.
We’re stuck in a bit of a flat spell to kick things off for the next few days. The first real chance to get the board wet isn’t until the afternoon of Saturday the 6th of September. That’s the first session worth paddling out for.
Saturday 6th September morning kicks off with a solid 6ft of swell from the S, with a 14-second period – that’s proper groundswell. The wind is a gentle NNW breeze, clean and cross-off, making for smooth conditions. The combined energy is a strong 1270 (moderate-to-strong wave energy). It’s a good call for experienced surfers.
Saturday afternoon gets even better. The swell drops a touch to 5ft from the S, but the period stretches to 13 seconds, and the wind holds clean. The energy jumps to 1430 (strong wave energy). The water is a balmy 74°, which is 6° warmer than normal for the time of year – that’s very unusual, so you can leave the wetsuit at home. This afternoon is the standout of the whole outlook. Clean, solid, long-period S swell. It’s excellent for experienced surfers.
Sunday 7th September morning sees a bump in size to 6ft from the SSW, but the wind swings onshore from the W, making it choppy. The energy is still strong at 1258, but the quality drops. The afternoon gets worse with a 25 km/h WNW cross-on wind and poor conditions. Nothing to write home about.
From Monday 8th September through to the end of the outlook, the surf gets smaller and weaker. The wind is mostly cross-on or onshore, and the energy drops off into the 200-600 range (weak-to-moderate). The swell height stays under 3ft for most of the second week. There are a few long-period traces (16-19 seconds) on the 9th, 10th, and 18th, but the swell is too small to make anything of it, and the wind is often unfavourable.
Terra Mar is a point break, so it handles those long-period swells well, but with the size so tiny and the wind mostly messy, it’s a frustrating stretch. The best bet for a paddle is definitely that Saturday afternoon session. After that, you’re looking at a long gap of small, poor-quality surf until the 20th, and even that is only 3ft.
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.
