The Lowdown
Alright, folks, Rusty here. Let's talk about what's on the menu for Terra Mar over the next couple of weeks. This is a point break that's usually pretty consistent, but right now we're looking at a stretch that's a bit of a mixed bag. The water is sitting at 72.5°, which is a solid 5.8° warmer than what we'd normally expect for this time of year – that's a real standout, way warmer than usual.
The first few days are basically a write-off. Starting Sunday afternoon the 19th, we've got a tiny 3 ft SW swell, but it's cross-on and choppy, with only moderate energy (812). Not worth paddling out. Monday and Tuesday the 20th and 21st are similar – small, onshore, and marginal. Wednesday the 22nd and Thursday the 23rd are just as poor, with the wave energy dropping into the weak range. Honestly, the surf is flat or messy through the first week.
Now, things start to get a bit more interesting from Friday the 24th. The morning brings a tiny 2.3 ft SW swell, but check out the period – 24 seconds, that's a proper groundswell. The combined energy jumps to strong (1132). The wind is onshore from the SW at 9 mph, so it's not perfectly clean, but for a point break that long period should wrap in nicely. It's still a marginal call, but this is the first hint of life. The afternoon picks up a bit to 4 ft, but the period drops to 13 seconds and the energy is still strong.
The real standout lands on Saturday August 1st. That afternoon, we're looking at 6 ft of SSW swell with a 13-second period, and the combined energy is strong (1077). The wind is light onshore from the SW at 6 mph – not glassy, but light enough that it won't wreck it. This is the best wave size we've seen, and for a point break, those conditions should offer some fun, wrapping lines. That said, it's a bit punchy for beginners at 6 ft, and the onshore wind means it won't be perfect. But compared to the rest of the window, this is the pick. The morning of August 1st is also decent with 6 ft and light onshore wind, but the afternoon edges it out.

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.
