The Lowdown
What’s the story, crew? Rusty here, checking in on Terra Mar. It’s a long forecast with a few bright spots, but we’ve gotta sift through the junk first.
The water is a balmy 76°F, which is a massive 8°F warmer than usual – feels like a hot tub out there.
Forget the first few days. Thursday the 3rd and Friday the 4th of September are a bust – weak, small, and messy.
Things start to look a bit more interesting on Sunday morning, September 6th. We’ve got a 6ft south swell with a 14-second period and moderate energy (1489). The wind is light and cross-shore, so it should be rideable. Sunday afternoon bumps it up to 7ft, but the outlook is similar.
The real highlight lands on Monday, September 7th. There’s a strong 7ft swell from the SSW, with a 14-second period and powerful energy (1514 in the morning). The wind is a cross-onshore, so it won’t be perfect, but the size and push are undeniable. At over 6ft, this is for experienced surfers only. Beginners, sit this one out.
From there, it’s a slow downhill slide. The swell fades, the wind gets messy, and by the middle of the month we’re scraping together small, weak waves. There’s a moment on Thursday, September 17th afternoon with a 2ft swell and a very long 21-second period, but the wind is cross-onshore and energy is moderate (544). Not your day.
Bottom line: your best bet is the Sunday into Monday, September 7th window. After that, it’s a waiting game for the next pulse.
Get some while you can.
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.
