The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s going on for our local stretch.
Right off the bat, I gotta be honest with you – the next week or so is a bit of a slow burner. We’ve got some swell on the way, but for the first few days, the wind and the size just aren’t playing ball. There’s a real gap in quality surf from now until the end of the first week of September. Don’t bother checking the cam just yet.
Monday the 31st has a little 3ft to 3ft SSW swell rolling in at Swamis, but it’s all onshore wind and the water’s feeling *much warmer than normal* – the temp is sitting at 77° with a huge anomaly of 9°. It’s a lake out there, but not a clean one. The combined energy is moderate (568), but the conditions are poor. Tuesday and Wednesday are more of the same, with tiny 2ft to 3ft waves and mucky wind. We're looking at a solid 5-day stretch of nothing worth paddling out for.
Finally, things start to move on Saturday the 5th. The morning’s still a bit marginal, but the afternoon sees a 5ft S swell at 14 seconds building in, with light offshore wind. The wave energy cranks up to 1446 (strong) and the wind is glassy. That’s our first real window. Sunday the 6th gets bigger – 7ft to 8ft S swell – but the morning has light rain. The afternoon cleans right up with a cross-offshore breeze from the NNE. This is getting interesting.
Now, the standout. Monday morning, September 7th is the best we’ve got. Swamis sees a solid 10ft S swell, with a 14-second period, and the wind is light and cross-offshore from the ESE. The combined energy is a massive 3445 (very strong). This is big, powerful groundswell. The water temp is still warm, but the anomaly data isn’t in the raw forecast for this session. The note says *excellent surf conditions for experienced surfers*, and that’s spot on. At 10ft, this is for experienced crew only. The long period means it’ll lurch and draw at Swamis, which is a beach-and-reef setup, so expect some proper walls. This is the one to circle.
After that, things drop off fast. Monday afternoon sees the wind howling from the SSE at 22 mph, and Tuesday is a messy, blown-out 10ft with a short 9-10 second period. That’s a cleanup job. The rest of the second week fades into smaller, wind-affected, or weak 1ft to 3ft SW swell. The energy drops back to weak (around 168 to 235). It’s a long, quiet run from the 9th of September through to the 15th.
So, to sum it up: the first week is a write-off, but that Monday the 7th is a real diamond in the rough. If you’re keen and experienced, that’s your window. Otherwise, give it a miss.
Rusty.

Information about the Swamis Surf forecast
The above surf forecast table for Swamis provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Swamis can be found by selecting the local surf guide option on the grey menu. Our Swamis 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 (Swamis) 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 Swamis 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.
Swamis is 5 km (3 miles) from the city of Encinitas. If you plan a vacation in San Diego County, look for hotels and other accommodation in Encinitas. Encinitas has rooms for a wide range of budgets as well as car hire and transport links.
