The Lowdown
Alright, Rusty here. Let's talk about what's brewing for the next couple of weeks at Swamis.
Right off the bat, I gotta be straight with you – it's looking pretty bleak for a while. We've got a long stretch of small, weak surf ahead. The first recommendation we see isn't until Sunday the 16th of August, and even that's a bit of a tease. The water temp is sitting at 73°F, which is 5°F warmer than normal for this time of year – that's way above average, a real standout.
That Sunday (16th) morning session is the only one in the first week that has any spark of life. You're looking at a 3ft SSW groundswell with a very long 15-second period. It’s a clean west offshore wind, so the faces should be glassy. The combined energy here is 525 (moderate), so there's actually some decent push in the water. For a reef-and-beach setup like Swamis, that long period groundswell can line up some nice, reeling lines, but it's only about 3ft, so it's not going to be pumping. It's the one true standout in this whole outlook, but it's not a classic day. The afternoon and the whole of Monday, Tuesday and beyond just fall apart with poor conditions or marginal tide issues.
For the rest of the first week and into the second, it's a real grind. The swell doesn't budge much, mostly hovering between 2ft and 3ft, with periods dropping to 13-14 seconds. The winds are mostly light offshore or light cross-on, but the energy just isn't there – the combined energy drops down to the 200-400s range. It's a classic case of having a clean window but nothing to ride. That run of poor surf lasts all the way into the second week.
If you are scanning the horizon, there's a little lift towards the very end of the month. Saturday the 29th of August morning shows a 3ft SSW swell that’s showing a bit more life in the guidance, but don't get too stoked. By Sunday the 30th, the winds swing cross-on and the quality dips again. The whole 16 days are a flat spell with a few very small windows.
The bottom line: if you've got to get wet, be on the water early Sunday morning (16th) when that 3ft swell and clean offshore wind line up. It’s the only real shot. For the rest, you’re better off waiting for a proper bump in the forecast.
Stay patient, 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.
