The Lowdown
Alright folks, Rusty here. Let’s have a look at what Swamis has in store for us over the next couple of weeks.
First off, we’ve got a bit of a quiet start. The early part of the window is looking pretty average, with only small, relatively clean but quite weak surf on offer. The water is sitting at 75.7°, which is much warmer than normal for this time of year – a real 7.6° anomaly, so that’s a very unusual treat.
Thursday 3rd September is a write-off really. We’ve got a long-period, 2.3ft – 2.9ft southwest groundswell but the wind is a cross-on and onshore, making things choppy and messy. The combined energy is moderate (424-613), but the surf is poor. Not worth paddling out for.
Friday 4th into Saturday 5th sees a small bump. The swell picks up to around 3.3ft – 3.9ft from the SSW, with a decent period of 16-17 seconds. The energy is building (690-979). On Friday morning, a light SW cross-on breeze keeps it a bit rippled, but the afternoon goes onshore – still marginal. Saturday morning looks best with a light onshore breeze and a 3.3ft swell, but it’s still only a marginal call. The crowd factor is worth noting at Swamis – it’s *often* busy here, so don’t expect any solitude.
Sunday 6th September is where things get interesting. We’ve got a solid 6.6ft south swell, with a 14-second period and very strong energy readings (1591-1597). However, the wind is cross-on from the NW, which will put a bit of a chop on the face. This is getting into the “too big for beginners” territory, and at 6.6ft, it will be a handful for the average punter. The break is a beach and reef set-up, so that long-period groundswell could be a bit straight at times, but there’ll be some power.
The best window for some proper waves looks to be Monday 7th and Tuesday 8th September. The swell holds at 5.6ft – 6.6ft from the SSW, with energy staying strong (1172-1500). The key here is the wind: it’s a light to moderate onshore breeze from the WNW. That’s a clean, offshore wind for Swamis, which is a major positive. The waves will be lined up, powerful, and the period is still a solid 13-14 seconds. This is the standout. If you’re an experienced surfer, these are the sessions to target. The crowd will be there, but the quality will be worth the paddle.
From Wednesday 9th September onwards, the swell steadily drops. By the middle of the month, we’re down to 1.3ft – 2.6ft, with periods that extend out to 18-21 seconds, which is very long-period groundswell. The energy drops right off (220-689). The winds stay mostly light and onshore or cross-on, but the surf just isn’t there. The third week of September looks pretty flat, with a few small, weak pulses that are only marginal at best.
Overall, the standout is without a doubt Monday 7th and Tuesday 8th September. Solid 5.6ft – 6.6ft SSW groundswell, clean offshore winds, and strong energy. It’s not a beginner’s day, but for the competent surfer, that’s your window.

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.
