The Lowdown
Alright folks, Rusty here. Let’s check out what’s cooking for the next couple of weeks.
It’s a tough stretch to start. Right from the get-go, the surf is tiny and the winds are lousy. We’ve got a long run of marginal-to-poor days with light onshore and cross-onshore breezes that are just ruining any chance of clean waves. Wednesday morning the 16th kicks off with a small 3ft SSW groundswell at a very long 17 seconds, but the cross-on wind from the SW has it looking bumpy, and the combined energy is only moderate at 518. It doesn’t improve – Wednesday afternoon, all of Thursday, and into the weekend are mostly onshore and flat, with waves barely hitting 3ft and most days scoring a zero for surf quality. The water temp is about average for this time of year, nothing wild.
The only real standout that’s worth getting wet for is Monday the 21st of September. Swamis (beach and reef) will see a slight bump in swell height to 4ft from the SW with a solid 17-second period. That’s a long-period groundswell, so it’ll have real power and good shape, especially for a reefy setup like this. The combined energy climbs into the moderate-strong range at 724. The catch: it’s a light cross-on breeze from the SW. Not perfect, but it’s the best size and energy of the whole forecast. Crowds are often a problem here, and since the swell direction matches the optimum (W), you’ll want to be there early. By afternoon the wind turns more onshore.
After Monday, it’s back downhill fast. Tuesday and Wednesday of next week are poor again with 3ft swell and onshore winds. There’s another little flicker on Sunday the 28th with a 3ft SSW swell at 11 seconds pushing through, but the energy is moderate and winds are light onshore – still nowhere near Monday’s window. Then the final week of September and into October 1st sees the swell drop to 2–3ft with long-period energy but zero quality due to bad wind.
Bottom line: Monday the 21st is your best bet, and even that’s a bit borderline. Everything else is a washout unless things change. If you’re into kiteboarding, those breezy afternoons might look more interesting than a surfboard session.
Rusty out.

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.
