The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks. We’re setting our sights on Terra Mar, and I gotta be straight with you – the first bite of this forecast is a bit of a mixed bag. The swell is coming, but it’s bringing some tricky conditions with it.
The first real surfable energy arrives on Monday, July 27th. We’re looking at a solid pulse of long-period groundswell from the SSW, with wave heights around 4 ft and a period of 18 seconds. That’s a lot of energy in the water – the combined energy reading is a hefty 1126. The water temp is about average for this time of year. The trouble is, the wind is blowing straight onshore from the SW at 6 mph. It’s a light breeze, sure, but onshore wind is onshore wind, and it’s going to mess with the shape. The notes say the surf is marginal, and the tide might be a factor. This is a point break, and with that long period, it should handle the swell direction fine, but it won’t be a classic.
Tuesday the 28th is more of the same story. The swell stays solid at 4 ft, still from the SSW, with a period of 17 seconds, and the energy is still high at 1066. The wind is still onshore, switching a bit to the SSW at 9 mph. Still a gentle breeze, but still onshore. It’s a tough one – there’s plenty of push, but it’s going to be bumpy. The break is fairly consistent, so it will be breaking, but it’s not going to be the cleanest ride.
Now, if you’re looking for the best of a not-great bunch, you’d have to point to Thursday morning, July 30th. The swell drops a little to 5 ft from the S, with a period of 14 seconds. The wind shifts to the WSW at 6 mph, which is a cross-on breeze. It’s not clean, but it’s a better angle than straight onshore, and the energy is still a solid 999. It’s the closest we get to a decent wave, but don’t expect perfection.
Friday the 31st is similar, with 6 ft from the S in the morning, but the wind stays cross-on from the WSW. The afternoon gets a bit choppier as the wind picks up to 9 mph.
After that, the party starts winding down. From Saturday, August 1st, the swell drops off noticeably. The energy takes a dive to 608, and the wave heights begin to shrink. By Sunday, August 2nd, we’re into the doldrums. The forecast calls it poor, and I agree. Wave heights are down to 2 ft, and the energy is a paltry 203. That’s a big gap of no good surf stretching from Sunday, August 2nd, all the way through to the end of the forecast on Tuesday, August 11th. The swell is just too small and weak to do anything with, and the wind is mostly onshore or cross-onshore.
So, the honest truth? There’s no true standout here. The best window is Monday through Wednesday, July 27th to 29th, if you’re desperate for a paddle and can handle onshore bumps. Thursday morning, July 30th, is the pick of the litter, but it’s still not a day to write home about. After that, it’s a long, flat spell. The water temperature is average, and the crowds are listed as “sometimes” – but with surf this marginal, I reckon you’ll have the place to yourself.
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.
