The Lowdown
Listen up, crew – Rusty here, on the Terra Mar report.
Over the next couple weeks, it’s mostly a flat, choppy mess. The best you're gonna find is a small, clean wave on Wednesday afternoon, August 26th, and maybe Thursday morning, August 27th. The rest is scrap.
Water temp is about 74° right now – way warmer than normal for this time of year, over three degrees above average. Feels like a bathtub.
Tuesday the 25th kicks off with a tiny 0.8ft south-west groundswell (16 seconds, long-period juice), but the wind is cross-on from the WSW. Energy’s weak – only 400 – so don’t expect much.
Wednesday the 26th is your best bet. We’ve got 1ft of south swell at 12 seconds, with a light offshore from the SW. That’s clean, lined-up water for a point break like Terra Mar. The afternoon keeps that 1ft with even lighter wind – just a slight breeze. Energy is up around 670-753 – moderate and punchy. This is the pick. It’s a beginner-friendly break, and with that offshore wind, it’ll be smooth as glass. The swell direction is south, which is a little off the optimum WSW, but it’ll still work nicely.
Thursday the 27th holds onto that 1ft south swell at 12 seconds, with light offshore wind again. Energy around 644. Good, just a bit smaller.
Then it goes downhill. From Friday the 28th onward, the swell drops to under 1ft, the wind goes cross-on or onshore, and it gets choppy. Saturday the 29th has 1.0-1ft from the south-southwest with long periods (16-17 seconds), but that cross-on breeze messes up the face. Bumpy.
The whole second week – from September 1st through the 9th – is a bust. Small swells (0.6-1ft), onshore or cross-on wind, and energy drops into the 300-400 range by the 7th. That’s flat. The only tiny bump is September 9th with a 0.9ft, 17-second south-west swell, but cross-on wind spoils it again.
If you want a paddle, make it Wednesday August 26th afternoon or Thursday morning August 27th. Otherwise, save the gas. This spot is consistent enough that it won’t stay this bad forever, but this run is a stinker.
Rusty, signing off.

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.
