The Lowdown

Alright, folks, Rusty here. Let’s break down what’s happening at Terra Mar for the next couple of weeks.

Right off the bat, I gotta be straight with you – the surf is looking pretty flat and quiet. From Sunday the 9th through Thursday the 13th, the waves are small and messy. Swell is running 0.5m to 0.9m, mostly from the SSW. The wind is cross-onshore or onshore pretty much all the time, making things choppy. The wave energy is weak to moderate (under 400 in the readings), and every session is marked as poor. It’s just not worth suiting up.

Things start to look a little better around Friday the 14th. The swell gets a bit more consistent, and even though the wind is still a light cross-onshore, the wave energy climbs (reading 538 to 699). The waves are still small (0.7m to 0.8m), but the period stretches out to 18 seconds. That’s a nice long period groundswell, which means the waves will have some shape and push. It’s only marginal, but it’s the best we’ve seen. This carries through Saturday the 15th and into Sunday the 16th, with the swell size bumping up to 1.2m on Saturday afternoon and Sunday morning. The wave energy gets strong (over 700). The catch? The wind is still cross-onshore, so it’ll be a bit choppy, but for a point break like Terra Mar, that long period energy could still produce some rideable waves. Keep your hopes modest, but it’s a paddle-out situation.

After that, from Monday the 17th onward, we slide back into mediocrity. The swell drops, the wind stays cross-onshore, and the energy fades. By the second week, from the 21st to the 24th, we’re looking at tiny waves (0.4m to 0.6m) with a mix of onshore and cross-onshore breezes. It’s a proper flat spell. The water temperature is sitting at 24°C, which is much warmer than usual for this time of year – that’s over 4° warmer than normal, so you might not need a wetsuit, but you won’t need a board either.

The one standout, if you can call it that, is Friday the 14th and Saturday the 15th. The swell direction is SSW, and the guidance says the optimum is WSW, so it’s not a perfect match, but the long period (18 seconds) and the moderate wave energy make it the most interesting window. For a beginner-friendly point break, the 1.2m swell on Saturday morning is about as big as it gets in this forecast, and it’s not too big for learner boards. Just be ready for some chop.

Bottom line: It’s a quiet stretch. The first week is a write-off, and the second week is even smaller. If you’re desperate, Friday the 14th and Saturday the 15th are your best shot, but don’t expect any fireworks.

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.
