The Lowdown
Alright folks, Rusty here. Let’s break down the next 16 days at Terra Mar. It’s a pretty quiet start, so don’t rush to wax up just yet.
The first few days are a write-off. Wednesday the 2nd through Friday the 4th are all poor surf conditions with tiny swell and onshore or cross-onshore wind. The energy is weak (271 to 992), and the water is a wild 77°F – that’s 9°F warmer than it should be for this time of year, which is very unusual. You’ll be sweating in your wetsuit, but there’s nothing to ride anyway.
We start to see a pulse of energy building over the weekend. Saturday the 5th is still marginal with cross-onshore wind and a lumpy 4ft to 4ft, mainly from the S. The energy is starting to show (around 1100), but it’s not clean.
Now, the one standout in the whole window – Sunday the 6th. This is your best bet. The morning brings a clean 6ft of SSW swell with a 14-second period and a light cross-offshore wind from the N. The energy is strong (1506), and the guidance says it’s excellent for experienced surfers. That’s over 5ft, so it’s a bit much for beginners, but the clean conditions will make it a fun session for everyone else. It’s a point break, so that longer-period groundswell will wrap in nicely. The afternoon is still decent at 7ft, but the wind swings cross-shore. Crowds are possible here, so get in early.
After that, the quality drops off fast. Monday the 7th through Tuesday the 8th sees the swell fading and the wind turning cross-onshore and choppy. Energy drops from 1141 down to 802. Not worth it.
The rest of the second week is a long, disappointing run. From Wednesday the 9th all the way to Wednesday the 16th, it’s a mix of tiny 1ft to 4ft swell (mostly under 600 energy) and persistent cross-onshore wind. Conditions are poor or marginal at best. There’s a little spike on Thursday the 17th afternoon with a 3ft SW swell and a very long 21-second period, but it’s still cross-onshore and only rated marginal. A long-period swell like that (over 15 seconds) can be fickle at a point break, but it’s still a long shot.
Honestly, the only real day to pencil in is Sunday the 6th. Everything else is a gamble or a straight-up miss. Keep an eye on the forecasts, because a blank run like this doesn’t last forever around here.
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.
