The Lowdown
Alright, folks, Rusty here again. Let’s break down Terra Mar in feet and miles per hour, because I know some of you prefer it that way.
So, the big picture: it’s a pretty lackluster stretch ahead. We’re dealing with mostly onshore and cross-onshore breezes and swell that’s just too small to get excited about. There are a couple of days that might be worth a wet suit, but you’ve gotta be patient.
We start on Thursday, 30th July. There’s a long-period SSW groundswell running about 3 ft, with a period of 15 seconds. That longer period gives some push, but the wind is a light cross-onshore out of the WSW at about 6 mph. It leaves a little texture on the surface. The combined wave energy is moderate (798 dropping to 682). It’s marginal—fine for a log if you’re just looking to trim, but nothing to write home about.
Friday the 31st is more of the same: the swell bumps to about 4 ft from the S, but we’ve still got that cross-onshore wind. The afternoons get “fairly choppy,” and the energy stays moderate (706 to 531). Not a great day.
Then from Saturday the 1st of August through to about Tuesday the 12th of August, the surf goes to sleep. Swell heights drop to 2 ft to 2 ft, and most days are “poor surf conditions” with onshore winds. The combined energy falls into the weak range, often under 300. There’s a tiny bump on the afternoon of Saturday, 8th August with 3 ft SSW swell and a 16-second period, but the energy is moderate (377) and the wind is onshore. Honestly, it’s a big patch of flatness.
Now, the one event that catches my eye is around Friday the 7th through Tuesday the 11th of August. We see a very long-period groundswell—19 seconds! That’s a proper pulse from way out. But the size is tiny—only 2 ft to 3 ft. The energy climbs a bit, hitting 484 by Tuesday the 11th of August in the afternoon. For a point break like Terra Mar, that kind of period can wrap in nicely, but without offshore wind, it’s just a tease. The wind stays light and cross-onshore.
If I had to pick one best option, it’s the afternoon of Tuesday the 11th of August. That 18-second period swell at about 3 ft from the SSW with 484 combined energy is the biggest number we see in the whole 16 days. The wind is light cross-onshore, so it’s not perfect, but it’s the least bad we’ve got. Grab a big board and go for it.
Crowds at Terra Mar can show up “sometimes,” but with waves this small, you’ll likely have plenty of room.
Water temp is about average for the season, nothing strange.
So, there you go. A long flat spell from the start of August into the second week, with only a weak, small, long-period swell around the 11th worth a look. If you’re a beginner, the 30th and 31st of July might offer something, but for the rest of us? It’s a waiting game. Forecasts can always flip, but right now, it’s pretty quiet.
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.
