The Lowdown
G'day, I'm Rusty. Let's have a look at what's on offer for Terra Mar over the next few weeks.
Honestly, the outlook is a bit of a struggle for Terra Mar. For the first two weeks, from August 12th right through to August 26th, the surf is a real mixed bag of poor to marginal conditions. The water temperature is sitting at 75°, which is 7° warmer than normal for this time of year – that's a big anomaly, so it's feeling much warmer than usual.
The first standout doesn't really appear until Thursday, August 27th. On the morning of the 27th, there's a pulse of stronger energy. The swell is 4 ft from the S, with a period of 14 seconds, and the combined energy spikes to 1136. The wind is light and offshore from the SW at 3 mph, which should keep things clean. The wave comment is still "marginal," but it's the best we've seen. That afternoon, the wind swings to a cross-shore from the NW at 6 mph, with the swell period dropping to 13 seconds and energy at 993, so the morning is definitely the pick.
Before that, from August 12th to 26th, the swell is small, mostly between 1 ft and 4 ft, with cross-on winds from the W or WSW. The wind is often a gentle breeze, around 6-9 mph, and the wave state is described as "gentle cross-onshore and fairly choppy" or "poor surf conditions." The best of those days is maybe the 15th, with a 4 ft, 16-second swell from the SSW, but the cross-on wind still ruins it. The combined energy is moderate, reaching up to 718 on the 15th afternoon, but it doesn't translate to quality.
For the entire period, the wave types at Terra Mar are a point break, exposed to the WSW. The optimum swell direction is from the WSW, but the swell we're getting is mostly from the SSW or SW, which isn't ideal. It's a fairly consistent spot, but the conditions are just not cooperating.
The 27th of August is the only real standout. If you're a beginner, the 4 ft swell might be okay, but it's not ideal. The light offshore wind in the morning is a big positive. Just keep in mind that this is a long-range call, so it's promising but not locked in.
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.
