G’day, Rusty here. Let’s chew the fat on what’s coming for Terra Mar over the next couple weeks.
Honestly, it’s a bleak start. For the first week and a half, the surf is barely a ripple—waist-high or smaller, choppy cross-onshore winds, and just about nothing that gets your heart pumping. The energy numbers are low, mostly 200–500, so you’re not missing anything. You’d be better off waxing your board and waiting.
The one bright spot is the weekend of July 18th and 19th. On Saturday the 18th, we see a pulse of swell around 4ft from the S with a long 18-second period. That’s proper groundswell, and the combined energy hits 1299 (moderate-strong). Morning winds are light from the SW, so it’s offshore and glassy—prime conditions. Sunday the 19th brings bigger surf, around 6ft from the S with energy up to 1747, but the wind swings cross-on from the WNW, making it a bit lumpy. Terra Mar is a point break that’s beginner-friendly, so 6ft is getting a bit much for the newbies, but for the crew who can handle it, it’s the pick of the month. That long-period swell will wrap around the point nicely, giving you longer rides but bigger gaps between sets.
Water temp is about average for this time of year.
Don’t bother with the early rubbish. Circle July 18th—that’s your day. Forecasts can change, but right now, that’s the story.

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.
